1. INTRODUCTION

Please read these instructions completely and carefully

before installing and operating the furnace.

The furnace must be installed and set up by a qualified

contractor

MODEL 80F

Model 80F is an oil-fired upflow forced air furnace, with

an output capacity range of 58,100 BTU/Hr. to 78,900

BTU/Hr. The 80F furnace equipped with a direct drive

blower may be installed in both horizontal positions.

MODEL 120F

Model 120F is an oil-fired upflow forced air furnace, with

an output capacity range of 87,700 BTU/Hr. to 113,400

BTU/Hr. The 120F furnace equipped with a direct drive

blower may be installed in both horizontal positions.

NOTE: Furnace models equipped with belt drive blowers

are not suitable for horizontal applications.

Both 80F & 120F Model furnaces are listed with the

Canadian Standards Association, (CSA), complies with

both Canadian and American (U.S.) standards for use

with No. 1 (Stove) and No. 2 (Furnace) Oil. Please refer

to the tables in the appendix for performance and

dimensional data.

DO NOT USE GASOLINE, CRANK CASE OIL,

OR ANY OIL CONTAINING GASOLINE.

In the United States of America, the installation of the

furnace and related equipment shall be installed in

accordance with the regulations of NFPA No. 31,

Installation of Oil Burning Equipment, as well as in

accordance with local codes.

In Canada, the installation of the furnace and related

equipment shall be installed in accordance with the

regulations of CAN/CSA - B139, Installation Code For

Oil Burning Equipment, as well as in accordance with

local codes.

When installation or application questions arise,

regulations prescribed in the National Codes and Local

Regulations take precedence over the general

instructions provided with this installation manual. When

in doubt, please consult your local authorities.

All models are shipped assembled and pre-wired. The

furnace should be carefully inspected for damage when

being unpacked.

2. HEAT LOSS

To determine the correct furnace and firing rate for an

application, it is necessary to calculate the maximum

hourly heat loss of the building based on local design

conditions. In new construction, the heat loss should be

calculated on a room-by-room basis to enable proper

sizing of the trunk and branch ducts. In retrofit

applications, a building shell (overall) heat loss

calculation may be used.

In the United States, Manual J. titled, "Load

Calculation" published by the Air Conditioning

Contractors of America, describes a suitable procedure

for calculating the maximum hourly heat loss.

In Canada, the maximum hourly heat loss may be

calculated in accordance with the procedures described

in the manuals of the Heating, Refrigeration and Air

Conditioning Institute of Canada (HRAI), or by other

method prescribed by authorities having jurisdiction that

are suitable for local conditions.

3. LOCATION OF UNIT

The furnace should be located such that the flue

connection to the chimney is short, direct and consists of

as few elbows as possible. When possible, the unit

should be centralized with respect to the supply and

return air duct work. A central location minimizes the

trunk duct sizing. All models may be installed on

combustible floors.

Minimum installation clearances are listed in Table 1.

SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE

29733 R2 06/01/2003

NOTE: The recommended installation clearances do not

take into consideration the clearances necessary to

replace the air filter or perform other routine

maintenance.

UP-FLOW INSTALLATION

Both furnaces models have been assembled for

installation in the up-flow position. Maintain all clearances

to combustibles as outlined in Table 1. Suggestion; as a

measure to prevent fuel oil from accumulating in

locations other than the fire pot, as could be the case in

the event of nozzle drip, install the furnace with an

approximate 2 degree slope from the oil burner casing

towards the fire pot. Use shims made of noncombustible

material.

In the upflow position, the heat exchanger support screw

shown in picture may be removed. This may be

preferable if the furnace rear panel will be inaccessible

after installation. The screw must be removed if the heat

exchanger must be removed from the cabinet. Do not

remove this screw if installing furnace in a horizontal

position.

HORIZONTAL INSTALLATION

The furnaces are assembled and shipped ready for

installation in the up-flow position. The direct drive

equipped furnace may be installed in either of the

horizontal positions; warm air discharging left or warm

air-discharging right by following these steps:

1. Rotate the furnace 90° to the desired position.

2. Remove the three nut and washer sets fastening the

oil burner assembly to the furnace (Beckett Burner)

or loosen the burner mount Allen screw (Riello

burner). Rotate the oil burner assembly to be in the

normal upright position.

3. Re-align the oil burner assembly to the combustion

chamber (fire-pot), then secure into place with the

three nut and washer sets (Beckett burner) or by re-

tightening the mounting Allen screw (Riello burner).

NON-SUSPENDED INSTALLATION

Maintain clearances to combustibles as outlined in Table

1. Installation on a combustible floor requires a clearance

of 1 inch. This can be done by using a noncombustible

material such as one-inch thick channel iron or similar

material. The furnace must be supported in such a way

as to not allow twisting or sagging of the cabinet.

Suggestion; as a measure to prevent fuel oil from

accumulating in locations other than the fire pot, as could

be the case in the event of nozzle drip, install the furnace

with an approximate 2 degree slope from the oil burner

casing towards the fire pot. Use shims made of

noncombustible material.

SUSPENDED INSTALLATION

Refer to Figure 1. Maintain clearances to combustibles

as outlined in Table 1. The furnace may be suspended by

field fabricating a cradle of angle iron and threaded rod.

Secure the furnace with 2 inch minimum slotted angle or

equivalent, as shown in Figure 1. The furnace must be

supported in such a way as to not allow twisting or

sagging of the cabinet. Position the supports so as to not

interfere with accessing the burner and blower

compartments. Suggestion; as a measure to prevent fuel

oil from accumulating in locations other than the fire pot,

as could be the case in the event of nozzle drip, install

the furnace with an approximate 2 degree slope from the

oil burner casing towards the fire pot.

4. AIR CONDITIONING APPLICATIONS

If the furnace is used in conjunction with air conditioning,

the furnace shall be installed in parallel with or upstream

from the evaporator coil to avoid condensation in the heat

exchanger. In a parallel installation, the dampers or air

controlling means must prevent chilled air from entering

the furnace. If the dampers are manually operated, there

must be a means of control to prevent the operation of

either system unless the dampers are in the full heat or

full cool position. The air heated by the furnace shall not

pass through a refrigeration unit unless the unit is

specifically approved for such service.

The blower speed must be checked and adjusted to

compensate for the pressure drop caused by the

evaporator coil. Refer to Appendix B for recommended

wiring and electrical connections of the air conditioning

controls.

5. COMBUSTION AIR

When a furnace is installed in the full basement of a

typical frame or brick house, infiltration is normally

adequate to provide air for combustion and draft

operation. If the furnace is installed in a closet or utility

room, two (2) ventilation openings must be provided

connecting to a well ventilated space (full basement,

living room or other room opening thereto, but not a

bedroom or bathroom). One opening shall be located 6"

from the top and bottom of the enclosure at the front of

the furnace. For furnaces located in buildings of

unusually tight construction, such as those with high

quality weather stripping, caulking, windows and doors, or

storm sashed windows, or where basement windows are

well sealed, a permanent opening communicating with a

well ventilated attic or with the outdoors shall be provided,

using a duct if necessary. Size all of the openings and

associated ductwork by the standards provided in the

latest Oil Installation Code editions; NFPA 31 in the

United States, CAN/CSA B139 in Canada. Take all fuel

burning appliances in the area into consideration when

calculating combustion and ventilation air requirements.

The Model CAS-2B-90E Furnace Boot manufactured by

Field Controls, Inc. may be used with the furnace to

obtain combustion air directly from outdoors. Use of this

device does not alter the need for ventilation air;

however, it does provide a good direct source of

combustion air and is connected directly to the oil burner.

29733 R2 06/01/2003

Figure 2: Common Chimney Problems

6. CHIMNEY VENTING

The chimney must be sized correctly and be in good

repair. If the chimney is oversized, there is a high risk of

the flue gases condensing resulting in damage to the

chimney and other venting parts. This problem may be

corrected by the use of an appropriately sized chimney

liner.

If the chimney serves the furnace only, the vent should

be sized at 4 inch minimum, 5 inch maximum. The table

below is based on dedicated venting. If the furnace is to

be co-vented with other appliances, refer to NFPA 31,

Standard for the Installation of Oil Burning Equipment and

NFPA 211, Standard for Chimneys, Fireplaces, Vents,

and Solid Fuel-Burning Appliances or CAN/CSA B139,

Installation Code For Oil Burning Equipment for correct

sizing information

120F (120) 165 185 195 205

IMPORTANT: The chimney must be capable of providing

sufficient draft at all times for the safe removal of the

products of combustion.

The chimney should be tested under “winter” conditions;

doors and windows closed, all other fossil fuel burning

appliances on, clothes dryer on, bathroom fans on, etc. If

the chimney cannot overcome the competition for air, it

will be necessary to access the reason for it, and take

corrective action. If the chimney is found to be sized

correctly and in good repair, it will probably be necessary

to re-evaluate the availability of combustion and

ventilation air, and take corrective action.

The flue pipe should be as short as possible with

horizontal pipes sloping upward toward the chimney at a

rate of one quarter inch to the foot. The flue pipe should

not be smaller in cross sectional area than the flue collar

on the furnace. The flue pipe should connect to the

chimney such that the flue pipe extends into, and

terminates flush with the inside surface of the chimney

liner. Seal the joint between the pipe and the lining. The

chimney outlet should be at least two feet above the

highest point of a peaked roof. All unused chimney

openings should be closed. Chimneys must conform to

local, provincial or state codes, or in the absence of local

regulations, to the requirements of the National Building

Code.

See Figure 2 and Table 3 for common chimney problems

and their remedies.

THE FURNACE MUST BE CONNECTED TO A FLUE

HAVING SUFFICIENT DRAFT AT ALL TIMES TO

ENSURE SAFE AND PROPER OPERATION OF THE

APPLIANCE.

The flue pipe must not be routed through concealed

space, because it must be visually checked for signs of

deterioration during the annual inspection and servicing.

The flue pipe must not pass through any floor or ceiling,

but may pass through a wall where suitable fire protection

provisions have been installed. Refer to the latest edition

of CAN/CSA B139 for rules governing the installation of

oil burning equipment. In the United States, refer to the

latest edition of NFPA 31 for regulations governing the

installation of oil burning equipment.

7. BAROMETRIC DAMPER CONTROL

This device is used in conjunction with conventional

chimney venting. This control (or draft regulator)

automatically maintains a constant negative pressure in

the furnace to obtain maximum efficiency. It ensures that

proper pressures are not exceeded. If the chimney does

not develop sufficient draft, the draft control cannot

function properly. The draft regulator, must be installed

within the same room or enclosure as the furnace, and

should not interfere with the combustion air supplied to

the burner. The control should be located a minimum of 3

flue pipe diameters from the furnace breeching and

29733 R2 06/01/2003

installed in accordance to the instructions supplied with

the regulator.

8. FURNACE CONTROLS

The furnace is controlled by either of two systems,

depending on the oil primary control and electronic fan

timer combination. System 1, used with Beckett burners,

includes the blower mounted Honeywell ST9103

ELECTRONIC FAN TIMER (EFT) combined with the R7184

OIL PRIMARY CONTROL. System 2, used with Riello

burners, includes the blower mounted Honeywell ST9103

ELECTRONIC FAN TIMER (EFT) combined with a

transformer / burner relay mounted internally on the 40F3

burner housing to operate the oil burner.

Figure 3: R7184 Oil Primary

The furnace functions are controlled by either System 1

or System 2, and bi-metallic snap disc limit switches.

These groupings also provide control for add-on air

conditioning. The ST9103 EFT is located in a control box

mounted to the blower support rails.

The circulating fan is controlled by the ST9103 EFT. The

heat delay-on time is fixed, at 30 seconds. This provides

a delay between the start of the burner and the start of

the circulating fan to reduce the amount of ambient

unheated air flowing through the ductwork. The end of

the circulating fan cycle is also delayed to remove

residual heat from the furnace. There are four delay-off

choices, 60, 90, 120 and 150 seconds, which are field

adjustable by manipulating the DIP switches on the

ST9103 EFT board.

The cooling delay-on and delay-off times are fixed at 30

seconds.

The furnace is protected against over-heating by fixed

high temperature limits. These controls are factory set

and are not field adjustable. If an over temperature

condition is detected, one or both limit switches will

interrupt power to the oil primary control, which will shut

of the oil burner. The circulating fan will continue to

operate. The high limit switches will automatically reset

when the furnace returns to a safe temperature.

9. ELECTRICAL CONNECTIONS

The furnace is listed by the Canadian Standards

Association (CSA). It is factory wired and requires

minimal field wiring. In the United States, the wiring must

be in accordance with the National Fire Protection

Association NFPA-70, National Electrical Code, and

with local codes and regulations. In Canada, all field

wiring should conform to CAN/CSA C22.1 Canadian

Electrical Code, Part 1, and by local codes, where they

prevail.

The furnace should be wired to a separate and dedicated

circuit in the main electrical panel; however, accessory

equipment such as electronic air cleaners and humidifiers

may be included on the furnace circuit. Although a

suitably located circuit breaker can be used as a service

switch, a separate service switch is advisable. The

service switch is necessary if reaching the circuit breaker

involves becoming close to the furnace, or if the furnace

is located between the circuit breaker and the means of

entry to the furnace room. The furnace switch (service

switch) should be clearly marked, installed in an easily

accessible area between the furnace and furnace room

entry, and be located in such a manner to reduce the

likelihood that it would be mistaken as a light switch or

similar device.

Figure 4: ST9103 EFT

29733 R2 06/01/2003

The power requirements for the HO-B Series models are:

120 VAC, 1 Æ, 60 Hz., 12A. 5-ton models: 120 VAC, 1 Æ,

60 Hz., 16A.

Accessories requiring 120 VAC power sources such as

electronic air cleaners and humidifier transformers may

be powered from the ST9103 EFT. Do not use the direct

drive motor connections as a power source, since there

is a high risk of damaging the accessories by exposure to

high voltage from the auto-generating windings of the

direct drive motor.

Thermostat wiring connections and air conditioning

contactor low voltage connections are shown in the wiring

diagrams. Some micro-electronic thermostats require

additional controls and wiring. Refer to the thermostat

manufacturer's instructions.

The thermostat should be located approximately 5 feet

above the floor, on an inside wall where there is good

natural air circulation, and where the thermostat will be

exposed to average room temperatures. Avoid locations

where the thermostat will be exposed to cold drafts, heat

from nearby lamps and appliances, exposure to sunlight,

heat from inside wall stacks, etc.

Normal heat anticipator setting: 0.1 A. For more precise

adjustment, the heat anticipator may be adjusted to the

amperage draw of the heating control circuit as

measured between the "R" and "W" terminals of the

thermostat. To reduce the risk of damaging the heat

anticipator, do not measure circuit without first removing

one of the two wires first. To determine the heating circuit

amperage draw:

1. Disconnect one of the “R” or “W” wires from the

thermostat terminal.

2. Connect an ammeter between the wire and the

thermostat terminal to which it was attached.

3. Note the amperage reading when the heating

contacts are closed. (System switch must be on

“HEAT” if so equipped.

4. Re-connect the thermostat wire. If the thermostat is

serving a combination heating and air conditioning

system, pay particular attention to polarity.

5. When the thermostat is reconnected and re-

plumbed, adjust the heat anticipator setting to match

the observed amperage reading.

10. HUMIDIFIER

A humidifier is an optional accessory available through

most heating supplies outlets. Installation should be

carried out in accordance with the humidifier

manufacturer's installation instructions. Water or water

droplets from the humidifier should not be allowed to

come into contact with the furnace heat exchanger.

Terminals (115 v) are provided on the ST9103 EFT

control. Do not use direct drive motor connections as a

source of power for 120 VAC humidifiers and humidifier

transformers.

11. OIL TANK

Oil storage tanks must be selected and installed in

compliance with applicable codes; in the United States,

NFPA 31, Standard for the Installation of Oil Burning

Equipment, Chapter 2. Observe all local codes and by-

laws. And in Canada, CAN/CSA-B139, Installation Code

for Oil Burning Equipment, Section 6

In general, the oil tank must be properly supported and

remain stable in both empty and full condition. The oil

tank must be fitted with vent and supply pipes to the

outdoors. Refer to the above-mentioned codes for sizing.

The vent pipe must be no less than 1¼ inches I.P.S., and

terminate with an appropriate vent cap in a location

where it will not be blocked. The fill pipe must be no less

than 2 inches I.P.S., and terminate with an appropriate

cap in a location where debris will not enter the fill pipe

during oil delivery.

If located indoors, the tank should normally be in the

lowest level, (cellar, basement, etc.). It must be equipped

with a shut-off valve at the tank outlet used for the oil

supply. The oil tank must be located as to not block the

furnace / room exit pathway. Observe all clearances

specified in the above-mentioned codes.

12. PIPING INSTALLATION

In the United States the installation must be in

accordance with the requirements of NFPA No. 31 and

local codes and regulations.

In Canada, the entire fuel system should be installed in

accordance with the requirements of CAN/CSA B139,

and local regulations. Use only approved fuel oil tanks

piping, fittings and oil filters.

Ensure that all fittings used in a copper oil line system are

high quality flare fittings. Do not use compression fittings.

Do not use Teflon tape on any fittings.

Pressurized or gravity feed installations must not exceed

3 PSIG. Pressures greater than 10 PSIG may cause

damage to the shaft seal. If the height of the oil stored in

a tank above the oil burner exceeds 11½ feet, it may be

necessary to use a pressure-regulating device approved

for this purpose.

29733 R2 06/01/2003

The furnaces may be installed with a one-pipe system

with gravity feed or lift. The maximum allowable lift on a

single line system is 8 feet. Lift should be measured from

the bottom (outlet) of the tank, to the inlet of the burner.

Sizing a single line system is complex because of the

difficulty estimating the pressure drop through each

fitting, bend and component in the line. In general, keep

single line systems short as possible. If the furnace is to

be installed in a suspended position, a two-pipe system

may be the better alternative. 2-stage oil pumps are not

available for either the Beckett or Riello burner. The

following chart shows the allowable line lengths

(horizontal + vertical) for single and two stage oil pumps.

All distances are in feet.

In retrofit applications, where an existing oil line system is

in place, a vacuum check will help determine the efficacy

of the existing oil line system The vacuum in a system

featuring a Beckett burner should not exceed 6” Hg. for a

single pipe system, nor 12” Hg. for a two-pipe system.

The vacuum in a system featuring a Riello burner should

not exceed 6” Hg. for a single pipe system, nor 11.44”

Hg. for a two-pipe system.

For additional information, see the installation information

sheet included in the documents envelope or affixed to

the oil burner.

NOTE: Both the Beckett and Riello oil burners require the

use of a bypass plug when converting from single-pipe to

two-pipe oil piping systems. See burner manufacturer’s

instructions.

NOTE: The Riello oil burner is manufactured with British

Parallel Thread pump ports. Adapters are supplied with

the oil burner to convert from British Parallel Thread to

NPT (National Pipe Thread). Direct connection of NPT

fittings to the Riello oil burner ports will result in damage

to the pump body. This also applies to pressure and

vacuum gauges. (See Riello manual)

13. OIL FILTER

All fuel systems should include an oil filter between the

fuel oil storage tank and the oil burner. For best results,

install the oil filter as close to the burner as possible.

When using an indoor oil tank, the oil filter may be

installed at the tank downstream from the shut-off valve.

If firing the furnace under the 0.65 gph rate, a 7 to 10

micron line filter should be installed as close to the oil

burner as possible.

14. OIL BURNER NOZZLES

The 80F Series furnace is certified for multiple firing

rates, ranging from 58,100 to 78,900 BTU/hr, while the

120F Series Furnace is certified for multiple firing rates of

87,000 113,400 BTU/hr. By changing the oil burner

nozzle within the specific Model Range, and temperature

rise, the furnace may be fired at an ideal rate for a wide

range of structures.

15. COMBUSTION CHAMBER

This furnace is equipped with an efficient cerafelt

combustion chamber. It is held in place by a retaining

bracket.

29733 R2 06/01/2003

CHECK THE ALIGNMENT OF THE COMBUSTION

CHAMBER AND OIL BURNER BEFORE FIRING. IT

IS POSSIBLE FOR THE COMBUSTION CHAMBER

TO SHIFT IF SUBJECTED TO ROUGH HANDLING

DURING TRANSIT.

The cerafelt combustion chamber is quite soft initially.

After firing, it becomes very brittle. Be sure to do all

alignment and positioning adjustments before the first

firing.

The combustion chamber should be inspected for

damage or carbon build up whenever the oil burner is

removed for repairs or routine maintenance.

BEFORE OPERATING THE FURNACE CHECK

BURNER ALIGNMENT WITH COMBUSTION

CHAMBER. THE END CONE OF THE AIR TUBE

MUST BE CENTRED TO THE ACCOMODATING

RING PROVIDED IN THE DESIGN OF THE

COMBUSTION CHAMBER. ADJUST ALIGNMENT

AND AMULET POSITION (RIELLO BURNER) AS

NECESSARY BEFORE FIRST FIRING.

16. BURNER ELECTRODES

Correct positioning of the electrode tips with respect to

each other, to the fuel oil nozzle, and to the rest of the

burners is essential for smooth light ups and proper

operation.

Beckett Oil Burner:

The electrode tips should be adjusted to a gap of 5/32”,

1/16” ahead of the nozzle, 5/16” above the centerline of

the nozzle. The “Z” dimension (front edge of the burner

head to the front face of the nozzle is 1-1/8 inches.

Riello Oil Burner:

The electrode tips should be adjusted to a gap of 5/32”,

3/32” ahead of the nozzle, 13/64” above the centerline of

the nozzle.

The electrode porcelains should be free of cracks, the

electrode tips should be tapered and free of burrs, and

the contact rods must be clean and be in firm contact

with the ignition transformer contact springs. The

electrodes must not come into contact with the burner

head.

17. OIL BURNER SET UP

The burner air supply is adjusted to maintain the fuel to

air ratio to obtain ideal combustion conditions. A lack of

air causes "soft" and "sooty" flames, resulting in soot

build-up throughout the heat exchanger passages.

Excess combustion air causes a bright roaring fire and

high stack temperatures resulting in poor fuel efficiency.

PREPARATIONS:

Drill a ¼” test port in the venting, ideally at least 2 flue

pipe diameters away from the furnace breeching, if

venting horizontally from the furnace, or from the flue

pipe elbow if venting vertically before reaching the

furnace. (see Figures 5 and 6).

The test port will allow flue gas samples to be taken and

stack temperatures to be measured.

Before starting the burner, check the burner alignment

with the combustion chamber (fire pot), check that the

correct nozzle is tightened into place, and that the burner

electrodes are properly positioned. The Beckett burner

bulk air band is should be closed, and the air shutter

initial setting should be approximately 7.00.

Refer to Table A-2, page 18, for Riello oil burner air

damper and turbulator settings.

Figure 5: Test port location for smoke test

horizontal.

Note A: Locate hole at least 6 inches on the furnace side

of the draft control.

Note B: Ideally, hole should be at least 12 inches from

breeching or elbow.

29733 R2 06/01/2003

Figure 6: Test port location for smoke test vertical.

PROCEDURE:

Start the burner and allow it to run at least ten minutes.

Set the air shutter to give a good flame visually. On

Beckett burners, the combustion air supply to the burner

is controlled by manipulating the air shutter on the left

side of the burner, and, if necessary, the bulk air band.

To adjust, loosen the bolt on the movable shutter. Move

the shutter gradually until a good flame (visually) has

been achieved. Re-snug the bolt.

Refer to the Riello Oil Burner Manual for setting the air

adjustment plate.

Figure 7: Checking Over-Fire Draft.

Check the initial draft setting as the furnace warms up.

The draft may be measured at the test port. The breech

draft should be approximately - 0.05” w.c. to obtain an

over fire draft reading of - 0.02 inches w.c.

Check the oil pump pressure. Refer to Table A1, page

18, for pump pressure settings.

After reaching steady state, take a smoke test. If not

indicating a trace, set the combustion air controls to

provide a trace.

Typically, the CO2 reading will range between 11.5% to

13.5%.

After the air adjustments have been completed, and the

air shutter or air adjustment plate has been secured, take

another smoke test to ensure that the values have not

changed.

NOTE: Riello Oil Burners - When taking final test

readings be sure that the burner cover is in place.

SMOKE TEST NOTE:

If oily or yellow smoke spots are found on the smoke test

filter paper, it is usually a sign of unburned fuel. This

indicates poor combustion. This type of problem may be

caused by excess draft, excess air, or contaminated fuel.

Do not ignore this indicator.

STACK TEMPERATURE:

Stack temperature will vary depending on fuel input,

circulating air blower speed, and burner set up, etc. In

general, stack temperature should typically range

between 380°F to 550°F, assuming that the combustion

air is approximately room temperature (65°F - 70°F). In

general, lower stack temperature indicates greater

efficiency; however, excessively low stack temperature

can lead to condensation forming in the chimney and / or

venting. Sulphur and similar contaminants in the fuel oil

will mix with condensation to form acids. Acids and

resultant chemical salts will cause rapid deterioration of

the chimney and venting components, and may attack

the furnace.

If the flue gases are below the range, it may be

necessary to slow down the blower fan. If the flue gases

are above the range, the blower fan may require

speeding up. Stack temperature varies directly with the

system temperature rise. System temperature rise is the

difference between the furnace outlet temperature and

furnace inlet temperature as measured in the vicinity of

the connection between the plenum take-offs and the

trunk ducts. Typical temperature rise values range

between 60° and 90°F for the Model 80F, 55°F and 85°F

for the Model 120F.

If the venting from the furnace to the chimney is long, or

exposed to cold ambient temperatures, it may be

necessary to use L-Vent as the vent connector to reduce

stack temperature loss to prevent condensation. The

venting should be inspected annually to ensure that it is

intact.

29733 R2 06/01/2003

IF THE FURNACE FAILS TO IGNITE, CHECK THE

OIL TANK FUEL GAUGE. IF THE FUEL GAUGE

SHOWS THAT OIL IS PRESENT, PRESS THE

RESET BUTTON ONCE ONLY. IF THE BURNER

FAILS TO IGNITE, CONTACT YOUR SERVICE

CONTRACTOR.

ALL FURNACE CONTROLS ARE SENSITIVE AND

SHOULD NOT BE SUBJECTED TO TAMPERING. IF

PROBLEMS PERSIST, CALL YOUR SERVICE

CONTRACTOR.

18. CIRCULATING AIR BLOWER

DIRECT DRIVE

The HO-B furnaces may be equipped with a direct drive

blower system. Direct drive blower speed adjustments

are not normally required in properly sized extended

plenum duct systems. The motor RPM and air CFM

delivery will vary automatically to accommodate

conditions within the usual range of external static

pressures typical of residential duct systems. Under-sized

duct systems may require a higher blower speed to

obtain a reasonable system temperature rise. Some older

duct systems were not designed to provide static

pressure. They typically feature special reducing fittings

at each branch run and lack block ends on the trunk

ducts. These systems may require modification to

provide some resistance to the airflow to prevent over-

amping of the direct drive blower motor. Selecting a lower

blower speed may correct this problem.

Direct drive blower speeds are adjusted by changing the

"hot" wires to the motor winding connections. Please

refer to wiring diagram in Appendix B or the wiring

diagram label affixed to the furnace. THE NEUTRAL

WIRE (normally the white wire) IS NEVER MOVED TO

ADJUST THE BLOWER SPEED.

DO NOT CONNECT POWER LEADS BETWEEN

MOTOR SPEEDS. THE NEUTRAL WIRE MUST

ALWAYS BE CONNECTED TO THE MOTOR'S

DESIGNATED NEUTRAL TERMINAL.

It is possible and acceptable to use a single blower speed

for both heating and cooling modes. The simplest

method to connect the wiring from both modes is to use a

"piggy-back connector" accommodating both wires on a

single motor tap. It is also acceptable to connect the

selected motor speed with a pigtail joined to both heating

and cooling speed wires with a wire nut. As a safety

precaution against accidental disconnection of the wires

by vibration, it is advisable to secure the wire nut and

wires with a few wraps of electricians tape.

If the joining of the blower speed wiring is done in the

furnace junction box, tape off both ends of the unused

wire.

BELT DRIVE

The HO-B Models are available with an optional belt drive

blower assembly. Belt drive blower systems can be

modified for a variety of speeds and air delivery by

adjusting the variable speed motor pulley, and / or by

changing the blower pulley.

The variable speed motor pulley may be adjusted by

loosening the 5/32 Allen set screw in the outer sheave,

and turning the outer sheave clockwise to increase

blower speed; counter clockwise to reduce blower speed.

Ensure that the setscrew is tightened at one of the "flat

spots", failure to do so will convert the variable speed

pulley to a fixed speed pulley by ruining the threads.

Changing the blower pulley can also modify the blower

speed. A smaller blower pulley will cause the blower to

turn faster; a larger pulley will reduce blower speed.

Large increases in blower speed will increase power

requirements. Check the amperage draw of the blower

motor after changes have been made. If the amperage

draw is greater than the value listed on the motor rating

plate, replace with a motor with a higher horsepower

rating.

The fan belt tension is very important. There should be a

deflection of between ¾ of an inch to 1 inch. Less

deflection places a strain on the blower bearings, and

increases start up amperage draw. More deflection

allows excess slippage and causes premature motor

pulley wear. Automotive belt dressings are not

recommended. A hard soap such as Sunlight® soap will

work well as a belt dressing, for the purpose of reducing

belt squeaks, etc. If used, the soap should be applied to

the sides of the belt only.

29733 R2 06/01/2003

THE BELT DRIVE COMPONENTS OPERATE AT

HIGH SPEEDS AND CAN EASILY SNAG LOOSE

CLOTHING, CAUSING SERIOUS PERSONAL

INJURY. THIS PROCEDURE SHOULD BE LEFT TO

TRAINED SERVICE PERSONNEL.

If the blower RPM operates above 1000 RPM, it is

advisable to replace the sintered bronze blower bearings

with roller Bearings.

The circulating fan start-up is delayed 30 or 45 seconds

(depending on EFT) in the heating mode.

The circulating fan start-up is delayed 30 seconds in the

cooling mode. The “fan off” is delayed 30 seconds in the

cooling mode.

The “fan off” delay may be field adjusted by manipulating

the dipswitches. See Figures 8.

Figure 8: Heating Mode “Blower Off” Timings, ST9103

Do not use the blower speed wires as a source of

power to accessories as electronic air cleaners and

humidifier transformers. The unused motor taps

auto-generate sufficiently high voltages to damage

accessory equipment. Use the terminals provided on

the ST9103 EFT

DO NOT START THE BURNER OR BLOWER FAN

19. MAINTENANCE AND SERVICE

A: Routine Maintenance By Home Owner

Other than remembering to arrange for the annual

professional servicing of the furnace by the service or

installation contractor, the most important routine service

performed by the homeowner is to maintain the air filter

or filters. A dirty filter can cause the furnace to over-heat,

fail to maintain indoor temperature during cold weather,

increase fuel consumption and cause component failure.

The furnace filter(s) should be inspected, cleaned or

replaced monthly. The furnace is factory equipped with a

semi-permanent type filter. If the filter is damaged,

replace with filters of the same size and type.

During the routine service, inspect the general condition

of the furnace watching for signs of oil leaks in the vicinity

of the oil burner, soot forming on any external part of the

furnace, soot forming around the joints in the vent pipe,

etc. If any of these conditions are present, please advice

your service or installation contractor.

29733 R2 06/01/2003

B: Annual Service By Contractor

THE COMBUSTION CHAMBER (FIREPOT) IS

FRAGILE. USE CARE WHEN INSPECTING AND

CLEANING THIS AREA.

The heat exchanger should be inspected periodically and

cleaned if necessary. if cleaning is necessary, SHUT

OFF POWER TO THE FURNACE and remove the

burner. Using a stiff brush with a wire handle, brush off

scale and soot from inside the drum and flue pipe. To

clean the radiator, remove the round covers on the inner

radiator access pipes located on the front panel between

the oil burner and the flue pipe.

A wire brush can be used to loosen dirt and debris on the

inside surfaces of the radiator. Clean out all accumulated

dirt, soot and debris with a wire handled brush and an

industrial vacuum cleaner. Replace the clean-out covers.

Most circulating fan motors are permanently lubricated by

the motor manufacturer. These motors will have no oil

ports. If the blower motor does contain oil ports, under

normal operating conditions it will not require oiling for the

first two years. Oil sparingly; a few drops in each oil port

with SAE 20 non-detergent oil. Oiling is most easily done

with a "tele-spout" oiler. This oilier has a long flexible

plastic spout. DO NOT OVER-LUBRICATE. Excess oil

may result in premature electric motor failure.

Inspect the blower fan. Clean it if necessary.

Oil Burner Maintenance: Follow the instructions of the oil

burner manufacturer. (See oil burner manufacturer's

instructions supplied with furnace). The oil burner nozzle

should be replaced annually. We recommend that the oil

filter be changed on an annual basis.

The venting system should be cleaned and inspected for

signs of deterioration. Replace pitted or perforated vent

pipe and fittings. The barometric damper should open

and close freely.

All electrical connections should be checked to ensure

tight connections. Safety controls such as the high limit

controls should be tested for functionality. The fan control

functions should be checked to ensure that all fan speeds

are operating properly.

20. FURNACE INSTALLATION SET UP

The furnace must be set up as the final step in the

installation.

A) The oil burner must be set up following the

procedures outlined in section 17: Oil Burner Set Up.

B) The 80F should operate within a temperature rise of

60°F to 90°F, the 120F; 55°F to 85°F. To determine the

temperature rise, measure the supply air and return air

temperatures when the furnace has reached steady state

conditions. This is the point at which the supply air

temperature stops increasing relative to the return air

temperature. The furnace may have to run 10 to 15

minutes to reach steady state conditions. The

measurements may be made with duct thermometers or

thermocouples used in conjunction with multi-meters with

temperature measurement capabilities.

The return air should be measured at a point where the

thermometer will be well within the air stream near the

furnace return air inlet. Actual location is not particularly

critical; however, avoid locations where the temperature

readings could be affected by humidifier bypass ducts,

the inside radius of elbows, etc.

The supply air temperature should be measured at a

point where the thermometer will be well within the air

stream near the furnace supply air outlet. Usually, the

side mid-point of the supply air plenum take-off is ideal,

providing it is out of the line of sight to the heat

exchanger. If the thermometer is within the line of sight of

the heat exchanger, the supply air readings may be

skewed by radiant heat from the heat exchanger. If the

plenum take-off is unsuitable, the supply air temperature

may be measured within the first 18 inches of the first

segment of supply air trunk duct.

If the temperature rise is outside the recommended

range, it may be adjusted on direct drive equipped units

by selecting alternate circulation fan motor speeds, or on

belt drive equipped units, by adjusting the variable speed

motor pulley or by blower pulley changes. If the

temperature rise is too high, speed the fan up. If the

temperature rise is too low, slow the fan down.

C) Keep in mind that the stack temperature varies

directly with the temperature rise. The higher the

temperature rise, the higher the stack temperature will

be, resulting in lower efficiency. The lower the

temperature rise, the lower the stack temperature will be,

which, in some cases, may allow condensation to form in

the chimney and other vent parts.

D) Test the high limit control to ensure that it is

operating correctly. This may be done by temporarily

removing the circulator fan heating wire or neutral wire.

On furnaces equipped with belt drive blowers, the fan belt

may be temporarily removed. Turn of electrical power to

the furnace before working with the motor wires. Be sure

to protect any removed wires from shorting out on metal

furnace parts. If the high limit test is successful, shut off

the electrical power to the furnace, restore the proper

29733 R2 06/01/2003

motor wiring, or replace the fan belt. Finally, restore

power to the furnace.

E) Operate the furnace through a minimum of three full

heating cycles. During this time, check for fuel oil leaks,

gross air leakage from the supply air ductwork, unusual

noises originating anywhere within the heating system

which may cause some concern or annoyance to the

home owner, etc.

F) Be sure that the homeowner is familiar with the

furnace. The homeowner should be aware of the location

of electrical circuit breaker or fuse, the location of any

electrical switches controlling the furnace, the location of

the oil tank shut-off valve and how to operate the valve.

The homeowner should know where the oil tank gauge is

located and how to read it.

It would be beneficial to review safety issues with the

home owner, such as the danger of storing combustibles

too close to the furnace, hanging anything on the furnace

vent pipe, and especially the dangers of indiscriminately

pressing the burner reset button.

IMPORTANT: Be sure that the home owner knows where

the burner reset switch is located, and is aware that the

reset switch is not to be activated more than once without

a look for the cause of the problem, (lack of fuel, etc.). Be

sure that the homeowner knows when to quit trying to

start the furnace during these conditions and who to call

for emergency service.

21. OPERATING INSTRUCTIONS

Before Lighting

Open all supply and return air registers and grilles.

Open all valves in oil pipes.

Turn on electric power supply.

To Light Unit

Set the thermostat above room temperature to call for

heat. The burner will start. NOTE: If the furnace has been

off for an extended period of time, it may be necessary to

press the RESET button on the primary combustion

control relay, (once only). If pressing the reset button

does not start the furnace, refer to Appendix C,

Troubleshooting.

After 30 or 45 seconds (depending on EFT), as the

furnace becomes warm, circulation fan will start.

The furnace will continue to run until the thermostat call

for heat is satisfied.

Set the thermostat below room temperature. The oil

burner will stop.

The air circulation blower will continue to run for 60, 90,

120 or 150 seconds after the oil burner has stopped,

depending on the dip switch settings.

To Shut Down Unit

Set the thermostat to the lowest possible setting.

Set the manual switch (if installed) in the Electrical Power

Supply Line to "OFF".

NOTE: If the furnace is to be shut down for an extended

period of time, close the oil supply valve to the oil burner.

DO NOT ATTEMPT TO START THE BURNER WHEN

EXCESS OIL HAS ACCUMULATED, WHEN THE

FURNACE IS FULL OF VAPOUR, OR WHEN THE

COMBUSTION CHAMBER IS VERY HOT. NEVER

BURN GARBAGE OR PAPER IN THE FURNACE, AND

NEVER LEAVE PAPER OR RAGS AROUND THE UNIT.

WIRING NOTES:

HO-B SERIES OIL FURNACE

CONTINUOUS FAN OPERATION:

The ST9103 EFT has provisions to run the blower motor

continuously on a speed lower than the cooling or heating

speeds. On a call for cooling, the fan motor will switch to

cooling speed, and on a call for heating, the fan will

switch to heating speed, each over-riding the continuous

low speed fan.

To obtain continuous low speed fan, route a 16 gauge

stranded, type TEW, 105°C wire from the CONT Terminal

on the ST9103 EFT to the low speed or medium low

speed motor terminal. Both wire ends will require ¼ inch

quick connects, (also known as “Faston” connectors or

¼” spade connectors). For additional control over the

continuous low speed fan circuit, a SPST toggle switch

may be wired in series between the motor terminal and

the ST9103 terminal. The continuous low speed fan

operation operates at 115 vac. Use appropriate wiring

methods to prevent electrical shock.

TURN OFF ELECTRICAL POWER TO THE

FURNACE WHEN SERVICING OR ALTERING

FURNACE WIRING.

FAILURE TO DO SO MAY RESULT IN SEVERE

PERSONAL INJURY, PROPERTY DAMAGE OR

DEATH.

ACCESSORIES:

The ST9103 EFT has provisions for supplying 115 volt

power to an electronic air cleaner (EAC) as well as 115

volts to a line voltage humidifier or humidifier step down

transformer. Both sets of terminals are ¼ inch quick

connect type, rated at 1 A each.

The EAC terminals provide power to an electronic air

cleaner whenever the heating or cooling speeds are

activated. Power is not provided when the continuous

speed is activated. If the electronic air cleaner must run

during continuous low speed fan operation, wire the EAC

into the furnace L1 terminal.

NOTE: It is seldom advisable to operate an electronic air

cleaner at the continuous low speed because of the

potential for excess ozone generation.

The HUM terminals provide power to a line voltage

humidifier or humidifier step down transformer when the

oil burner motor is operating.

THERMOSTAT HEATING CONNECTIONS:

The thermostat connections “R” and “W”, or “RH” and

“W” connect to the “R” and “W” screw terminals shown

on the left hand side of Figure 10, on the ST9103 EFT

located in the control box mounted to the blower

mounting rails.

Figure 9: Thermostat Connections ST9103

NOTE: All thermostat wires for both heating and cooling

connect to the furnace at this point. A factory installed

wiring harness connects the heating control functions to

the R7184 oil primary control.

Figure 8, page 14, shows the detail of the timed “Blower

Off” dipswitch settings. Figure 10 shows the dipswitch

location along the bottom edge of the control board, just

above the “Honeywell” label.

R7184 DETAILED SEQUENCE OF OPERATION

Power is applied to unit. The R7184 completes a self-diagnostic procedure. If no light or flame is present, and unit

passes its self-diagnostic procedure, the control enters into the idle mode.

Thermostat calls for heat:

A. Safety check is made for flame (4 second delay).

1. When flame is not present, the R7184 will apply power to the burner motor and igniter.

2. When flame is present, the control remains in the idle state.

B. Unit enters and completes a pre-purge period of 15 seconds, then applies power to the solenoid valve.

C. Control enters the trial for ignition state.

D. Control monitors the burner flame.

1. When flame is present, the control enters ignition carryover state. (Continues to spark for 10 sec.).

a. Provides continuous spark after flame is sensed to assure that burner remains lit.

b. Turns on LED diagnostic light.

c. Starts carryover timer.

i Flame and call for heat are monitored.

· If flame is lost and lockout timer has not expired, R7184 will return to trial for ignition state.

· If flame is lost and lockout timer has expired, R7184 will enter the recycle state.

¨ Recycle timer starts.

¨ Burner motor and igniter and solenoid valve are turned off.

¨ LED diagnostic light flashes slow.

¨ Returns to idle state when recycle timer expires (60 seconds).

E. Carryover timer expires.

i Enters run state.

· Igniter turns off.

Combustion continues until thermostat is satisfied, or R7184 detects a loss of flame and enters into Recycle Mode.

Thermostat is satisfied - call for heat is terminated:

· R7184 shuts off burner motor and solenoid valve.

· LED diagnostic light is off.

· R7184 returns to idle state.

29733 R2 06/01/2003

R7184 LED DIAGNOSTIC LIGHT

The LED diagnostic light has several functions. It

indicates the state or mode in which the oil burner is

operating. It will also indicate fault conditions, and help

determine cad cell resistance while the burner is

operating.

NORMAL CONDITIONS:

The LED diagnostic light will turn on when the burner

enters the carryover state; the point at which ignition

spark is on, and will remain on through the run state,

where the ignition spark is terminated but the burner

continues to fire.

The LED diagnostic light will turn off at the end of the

burner cycle as the R7184 enters the idle state, and

will remain off until the next heating cycle.

FAULT CONDITIONS:

If the LED diagnostic light is flashing quickly; 1 Hz (½

second on / ½ second off), the R7184 is in the lockout

state or in restricted mode. To exit the lockout state,

press the reset button.

If the LED diagnostic light is flashing slowly; ¼ Hz (2

seconds on / 2 seconds off), the R7184 is in the

recycle state. This indicates that flame sensing was

lost after the lockout timer expired during the ignition

carryover state. The R7184 will return to the idle state

within 60 seconds.

CAD CELL CONDITION:

If the LED diagnostic light is off, the cad cell is not

sensing flame.

If the LED diagnostic light is on, the cad cell is sensing

flame, or viewing ambient light.

The resistance of the cad cell may be checked while

the R7184 is in the run state by pressing the reset

button. The LED diagnostic light will flash the following

code:

TABLE C-2: CAD CELL RESISTANCE

Flashes Resistance in Ohms

1 Less than 400

2 Between 400 - 800

3 Between 800 – 1600

4 Between 1600 - 5000

Troubleshooting

IMPORTANT:

Due to the potential hazard of line voltage,

only a trained, experienced service

technician should perform the

troubleshooting procedure.

PRELIMINARY STEPS:

Check the diagnostic light for indications of burner

condition. Refer to R7184 LED DIAGNOSTIC LIGHT

section for details.

When simulating a call for heat at the R7184,

disconnect at least one thermostat lead wire from the

T1 - T2 terminals to prevent damage to the thermostat.

Neglecting this procedure may burn out the heat

anticipator of a standard 24 VAC thermostat, or cause

harm to components within a micro-electronic

thermostat.

Before checking the oil primary control, perform these

preliminary checks, (repair or replace controls as

necessary):

· check the power supply; fuse box or breaker, any

service switches, all wiring connections, and

burner motor reset button (if equipped).

· check the limit switches to ensure that the switch

contacts are closed.

· check the electrode gap and position.

· check the contacts between the oil primary control

and the electrodes.

· check oil supply (tank gauge).

· check the oil nozzle, oil filter, and oil valves.

· check the piping or tubing to the oil tank.

· check the oil pump pressure.

29733 R2 06/01/2003

CHECK OIL PRIMARY CONTROL AND IGNITOR

If the trouble does not appear to be in the burner or

ignition hardware, check the oil primary control and the

ignitor by using the following equipment:

à screwdriver.

à voltmeter (0 - 150 VAC)

à insulated jumper wires with both ends stripped.

over-load, determine why. Replace if necessary.

Furnace starts, but

cuts out requiring

manually resetting

the oil protector reset

button.

Photo Cell (Cad Cell)

defective.

If cad cell is dirty, clean it. (Determine why cad cell is

getting dirty). If cad cell is poorly aimed, realign it. NOTE:

The photocell should have a resistance of 100K W in

absence of light; a maximum of 1500 W in the presence

of light. Ensure that room light is not leaking into the cad

cell compartment. (see diagnostic light section).

No fuel oil.

Check fuel oil supply. Check that all hand operated fuel

oil valves are in the open position. Fill oil storage tank if

necessary.

Clogged nozzle. Replace nozzle with high quality replacement. Use rating

plate or Tables in Appendix A as a guide.

Clogged oil filter. Replace oil tank filter or in-line filter if used.

Low oil pump pressure.

Connect pressure gauge to oil pump. Adjust pump

pressure, or replace oil pump if necessary. Ensure that

erratic pressure readings are not caused by defective

fuel oil line.

Air getting into fuel oil

lines, or fuel oil line dirty,

clogged, or in some

manner defective.

Problem Possible Cause Remedy

Electrodes out of

adjustment or defective.

Check electrode settings. check electrodes for dirt build-

up or cracks in porcelain.

Poor transformer high

voltage connections or

defective transformer.

Check contacts between the igniter and electrodes. If

OK, replace the igniter

Fuel oil filter clogged. Replace fuel oil storage tank filter and / or fuel oil in-line

filter.

Defective oil pump. Check burner motor / fuel oil pump coupling. Check oil

pump pressure. Replace fuel oil pump if necessary.

Oil burner sputtering

at nozzle

Fuel oil line partially

clogged or contains air.

Bleed air from oil line. If problem persists, replace oil

line.

System temperature rise

too high.

System temperature rise ideally should not exceed 85°F.

Check for clogged air filters. Check blower fan for

excess dirt build-up or debris. Speed up blower fan if

necessary.

Poor “fan off” delay timing

selection, (fan stops too

soon).

Check “fan off” delay timing setting. Use a duct

thermometer in the supply air plenum take-off or first few

inches of the supply air trunk duct. Ideally, the fan will

shut off at a temperature of 90° - 100°F. Manipulate the

dip switch settings to come as close as possible to this

“fan off” temperature.

Fuel oil leak. Check fuel oil line for leaks. Repair or replace if

necessary.

Stack temperature too

high.

Check stack temperature. Stack temperatures will

normally range from 350° to 450°F. Check draft

regulator. Draft should be set to 0.02 in. w.c.

Excessive fuel oil

consumption.

Thermostat improperly

adjusted or in poor

location.

Check thermostat heat anticipator setting against

measured amperage draw. Increase heat anticipator

setting if necessary. If the thermostat is being influenced

by drafts, sunlight, duct work, etc., relocate to more

suitable location.

Insufficient combustion

air adjustment at oil

burner, or improper draft

pressure.

Adjust the oil burner combustion air band and draft

regulator to gain the highest practical CO2 or lowest

practical O2 content in the flue gases. See Burner Set

Up.

Too much smoke.

Heat exchanger partially

clogged.

Check for soot build-up in heat exchanger flue

passages, especially in the outer radiator.

Poor alignment between

oil burner blast tube and

fire pot.

Check alignment. blast tube should be centered with fire

pot burner opening. Oil burner head should be ¼ inch

back from the inside surface of the fire pot.

Flame impingement

caused by Incorrect

nozzle angle.

Check nozzle size and angle. (See Appendix A). Check

distance from head to inside surface of the fire pot.

Soot building up on

blast tube (end

coning).

Defective fire-pot Check fire-pot. Repair or replace.
