1. Safe Installation Requirements

Installation or repairs made by unqualified persons

can result in hazards to you and others. Installation

MUST conform with local codes or, in the absence of

local codes, with codes of all governmental authorities

having jurisdiction.

The information contained in this manual is intended

for use by a qualified service technician who is

experienced in such work, who is familiar with all

precautions and safety procedures required in such

work, and is equipped with the proper tools and test

instruments.

Failure to carefully read and follow all instructions in

this manual can result in furnace malfunction, death,

personal injury and/or property damage.

NOTE: This furnace is design certified by the American Gas

Association and the Canadian Gas Association for installation in

the United States and Canada. Refer to the appropriate codes,

along with this manual, for proper installation.

• This furnace is NOT approved for installation in mobile

homes, trailers or recreation vehicles.

• Do NOT use this furnace as a construction heater or to heat

a building that is under construction.

• Use only the Type of gas approved for this furnace (see Rat-

ing Plate on unit). Overfiring will result in failure of heat ex-

changer and cause dangerous operation. (Furnace can be

converted to L.E gas with approved kit.)

• Do NOT use open flame to test for gas leak.

• Ensure adequate combustion and ventilation air is provided

to the furnace.

• Seal supply and return air ducts.

• The vent system MUST be checked to determine that it is

the correct type and size.

• Install correct filter type and size.

• Unit MUST be installed so electrical components are pro-

tected from direct contact with water.

Safety Rules

Your unit is built to provide many years of safe and dependable

service providing it is properly installed and maintained. However,

abuse and/or improper use can shorten the life of the unit and

create hazards for you, the owner.

A. The U.S. Consumer Product Safety Commission recom-

mends that users of gas-burning appliances install carbon

monoxide detectors. There can be various sources of car-

bon monoxide in a building or dwelling. The sources could

be gas-fired clothes dryers, gas cooking stoves, water

heaters, furnaces, gas-fired fireplaces, wood fireplaces,

and several other items. Carbon monoxide can cause seri-

ous bodily injury and/or death. Therefore, to help alert

people of potentially dangerous carbon monoxide levels,

you should have carbon monoxide detectors listed by a na-

tionally recognized agency (e.g. Underwriters Laboratories

or International Approval Services) installed and main-

tained in the building or dwelling (see Note below).

B, There can be numerous sources of fire or smoke in a build-

ing or dwelling. Fire or smoke can ca use serious bodily inju-

ry, death, and/or property damage. Therefore, in order to

alert people of potentially dangerous fire or smoke, you

should have fire extinguisher and smoke detectors listed by

Underwriters Laboratories installed and maintained in the

building or dwelling (see Note below).

Note: The manufacturer of your furnace does not test any

detectors and makes no representations regarding any

brand or type of detector.

C. To ensure safe and efficient operation of your unit, you

should do the the following:

1. Thoroughly read this manual and labels on the unit.

This will help you understand how your unit operates and

the hazards involved with gas and electricity.

2, Do not use this unit if any part has been under water.

Immediately call a qualified service technician to inspect

the unit and to replace any part of the control system and

any gas control which has been under water.

3. Never obstruct the vent grilles, or any ducts that pro-

vide air to the unit. Air must be provided for proper com-

bustion and ventilation of flue gases.

Carbon monoxide or "CO" is a colorless and odorless gas

produced when fuel is not burned completely or when the

flame does not receive sufficient oxygen.

Freezing Temperatures and Your Structure

Freeze warning.

Turn off water system.

If your unit remains shut off during cold weather the

water pipes could freeze and burst, resulting in serious

water damage.

Your unit is equipped with safety devices that may keep it from op-

erating if sensors detect abnormal conditions such as clogged ex-

haust flues.

If the structure will be unattended during cold weather you should

take these precautions.

1. Turn off main supply water into the structure and drain the

water lines if possible. Open faucets in appropriate areas.

2, Have someone check the structure frequently during cold

weather to make sure it is warm enough to prevent pipes

from freezing. Suggest they call a qualified service agency,

if required.

Installation Requirements

1. Install furnace level.

2. Install furnace as centralized as practical with respect to the

heat distribution system.

3. Install the vent pipes as short as practical. (See Gas Vent

Installation section).

4. Do NOT install furnace directly on carpeting, tile or other

combustible material other than wood flooring.

5. Maintain clearance for fire safety and servicing. A front

clearance of 30" is minimum for access to the burner, con-

trols and filter.

Fire Hazard.

Place furnace on noncombustible cement board or sheet

metal on downflow applications.

Failure to install unit on noncombustible cement board or

sheet metal can result in death and/or personal injury

and/or property damage.

6. Use a raised base if the floor is damp or wet at times.

441 O1 201602

7. Residentialgarageinstallationsrequire:

•Burners and ignition sources installed at least 18" (457mm)

above the floor.

• Furnace must be located or physically protected from pos-

sible damage by a vehicle.

Horizontal Furnace Installation

Typical Horizontal Installation

IMPORTANT

NOTE: Inspect unit rating plate to be certain model number begins

with "NTV6", "NTP6", "VNE" or "TNE". This identifies unit as

horizontally mountable. If unit does NOT bear this designation,

you may NOT mount this unit horizontally. Horizontal furnace

may not be mounted on its back.

If you purchased a horizontally mountable furnace, it can be

installed horizontally in an attic, basement, crawl space, alcove, or

suspended from a ceiling in a basement or utility room in either a

right or left airflow position. See Figure 4.

The following minimum clearances to combustibles MUST be

maintained between the furnace and adjacent construction, as

shown in Figure 4. ONLY the corner of the cabinet is allowed to

contact the rafters. All other clearances should be observed as

shown in Figure 1, Figure 2, or Figure 3.

If the furnace is to be suspended from the floor joists in a crawl

space or the rafters in an attic, it is necessary to use steel pipe

straps or an angle iron frame to attach the furnace. These straps

should be attached to the furnace with sheet metal screws and to

the rafters or joists with bolts. The preferred method is to use an

angle iron frame bolted to the rafters or joists.

Thirty inches (30") is recommended between the front of the fur-

nace and adjacent construction or other appliances. This should

be maintained for service clearance.

Keep all insulating materials clear from Iouvered door. Insulating

materials may be combustible.

It is recommended for further fire protection that cement board or

sheet metal is placed between the furnace and the combustible

wood floor and extend 12" (300mm) beyond the front of the fur-

nace louver door. (This is a recommendation only, not a require-

ment).

This furnace MUST NOT be installed directly on carpeting or tile

or other combustible material other than wood flooring or sup-

ports.

3. Combustion & Ventilation Air

Poison carbon monoxide gas hazard.

Use methods described here to provide combustion and

ventilation air.

Failure to provide adequate combustion and ventilation

air can result in death and/or personal injury.

Furnaces require ventilation openings to provide sufficient air for

proper combustion and ventilation of flue gases. All duct or open-

ings for su pplying combustion and ventilation air must comply with

the gas codes, or in the absence of local codes, the applicable na-

tional codes.

When the installation is complete, check that all appliances have

adequate combustion air and are venting properly. See Venting

And Combustion Air Check in Section 4 of this manual.

An unconfined space is defined as an area having a minimum vol-

ume of 50 cubic feet per 1,000 BTUH total input rating for all gas

appliances in area.

Adjoining rooms can be considered part of an unconfined area if

there are no doors between rooms.

Poison carbon monoxide gas hazard.

Most homes will require additional air.

An unconfined space or homes with tight construction

may not have adequate air infiltration for proper

combustion and ventilation of flue gases.

Failure to supply additional air by means of ventilation

grilles or ducts could result in death and/or personal

injury.

An attic or crawl space may be considered an unconfined space

provided there are adequate ventilation openings directly to out-

doors. Openings MUST remain open and NOT have any means of

being closed off. Ventilation openings to outdoors MUST be at

least I square inch of free area per 4,000 BTU H oftotal input rating

for all gas appliances in area.

In unconfined spaces, infiltration should be adequate to provide

air for combustion, ventilation and dilution of flue gases. However,

in buildings with unusually tight construction, additional air MUST

be provided using the methods described in section titled Con-

fined Space Installation:

4. Gas Vent Installation

Poison carbon monoxide gas, fire and explosion

hazard.

Ventilation Air

Some provincial codes and local municipalities require ventilation

or make-up air be brought into the conditioned space as replace-

ment air. Whichever method is used, the mixed return air tempera-

ture across the heat exchanger MUST not fall below 60°F or flue

gases will condense in the heat exchanger. This will shorten the

life of the heat exchanger and possibly void your warranty.

Read and follow all instructions in this section.

Failure to properly vent this furnace can result in death,

personal injury and/or property damage.

Install the vent in compliance with codes of the country having ju-

risdiction, local codes or ordinances and these instructions.

Poison carbon monoxide gas hazard.

If this furnace is replacing a previously common-vented

furnace, it may be necessary to resize the existing

chimney liner or vent to prevent over sizing problems for

the other remaining appliances(s). See codes of country

having jurisdiction.

Failure to properly vent this furnace or other appliances

can result in death, personal injury and/or property

damage.

These fan assisted combustion furnaces have been classified as

Category [ appliances which means that they MUST operate with

a negative vent pressure.

Category I Safe Venting Requirements

NOTE: The following instructions comply with the United States

National Fuel Gas Code. Based on the highest input rate on the

furnace rating plate.

If a Category [vent passes through an attic, any concealed

space or floor, use ONLY Type B or Type L double wall vent

pipe. If vent pipe passes through interior wall, use type B

vent pipe with ventilated thimble ONLY.

2. Do NOT vent furnace into any chimney serving an open

fireplace or solid fuel burning appliance.

3. Use the same diameter Category [connector or pipe as

permitted by the United States National Fuel Gas Code

venting tables.

4. Keep vertical Category [vent pipe or vent connector runs as

short and direct as possible.

5. Vertical outdoor runs of type B or ANY single wall vent pipe

below the roof line are NOT permitted.

6. Slope all horizontal runs up away from furnace a minimum

of 1/4" per foot.

7. Support all horizontal vent pipe every 6' using proper

clamps and metal straps.

8. Check existing gas vent or chimney to ensure they meet

clearances and local codes.

The furnace MUST be connected to a factory built chimney

or vent complying with a recognized standard. Venting into

a masonry or concrete chimney is only permitted as

outlined in the United States National Fuel Gas Code

venting tables or Masonry Chimney section in these

instructions.

441 01 2016 02

Venting and Combustion Air Check

NOTE: If this installation removes an existing furnace from a vent-

ing system serving one or more other appliances, and to make

sure there is adequate combustion air for all appliances, MAKE

THE FOLLOWING CHECK.

Seal any unused openings in the venting system.

Visuallyinspect the venting system for proper size and hori-

zontal pitch to ensure there is no blockage or restriction,

leakage, corrosion or other deficiencies which could cause

an unsafe condition.

3. Insofar as is practical, close all doors and windows and all

doors between the space in which the appliance(s) remain-

ing connected to the venting system are located and other

spaces of the building.

4. Turn on clothes dryers and any appliance not connected to

the venting system. Turn on any exhaust fans, such as

range hoods and bathroom exhausts, so they will operate at

maximum speed. Do not operate a summer exhaust fan.

Close fireplace dampers.

5. Follow the lighting instructions for each appliance being in-

spected. Adjust thermostat so appliance(s) will operate

continuously.

6. Allow 5 minutes of main burner operation, then check for

spillage at the draft hood relief opening of each appliance.

Use the flame of a match or candle (Figure 6).

7. After it has been determined that each appliance vents

properly, return doors, windows, appliances etc. to their

normal condition.

8. If improper venting is observed, the cause MUST be cor-

rected.

NOTE: If flame pulls towards draft hood, this indicates sufficient

infiltration air.

Venting to Existing Masonry Chimney

NOTE: The tables and notes referred to below are found in the

most recent printing of the United States National Fuel Gas

Code venting tables.

Use the United States National Fuel Gas Code or N FGC Tables to

size the chimney or vent. Dedicated venting of one fan assisted

furnace into any masonry chimney is restricted. The chimney

must first be lined with either type B vent sized in accordance with

tables 1 or 2 or a listed single wall, metal lining system, sized in

accordance with the vent tables.

Listed, corrugated metallic chimney liner systems in masonry

chimneys shall be sized by using United States National Fuel

Gas Code tables for dedicated venting and United States Na-

tional Fuel Gas Code tables for common venting with the maxi-

mum capacity reduced by 20% (0.80 X maximum capacity) and

the minimum capacity as shown in the applicable table. Corru-

gated metal vent systems installed with bends or offsets require

additional reduction of 10% of the vent capacity for each 90 ° el-

bow.

NOTE: Two(2) 45° elbows are equivalent to one (1) 90° elbow.

Combined Venting into a Masonry Chimney

Venting into a masonry or concrete chimney is only per-

mitted as outlined in the United States National Fuel Gas

Code venting tables. Follow all safe venting requirements.

5. Horizontal Venting

Category ] Furnaces With External Power

Venters

In order to maintain a Category ]classification of fan assisted fur-

naces when vented horizontally with sidewall termination, a power

venter is REQUIRED to maintain a negative pressure in the vent-

ing system. Please consult the Fields Controls Co. or Tjernlund

Products, Inc. for power Venters certified for use with our fur-

Races.

Vent Termination

Venting Through a Non-Combustible and

Combustible Wall

CAUTION

It is the responsibility of the installer to properly termi-

nate the vent and provide adequate shielding. This is

essential in order to avoid water/ice damage to build-

ing, shrubs and walk-ways.

Consult External Power Venter manufacturer instructions.

6. Gas Supply and Piping

Poison carbon monoxide gas hazard.

Models designated for Natural Gas are to be used with

Natural Gas ONLY, unless properly converted to use

with LP gas.

Failure to follow these instructions can result in death,

personal injury and/or property damage.

Gas Supply Requirements

•Use only the Type of gas approved for this furnace. See rat-

ing plate for approved gas type.

• Gas input must not exceed the rated input shown on the rat-

ing plate. Overfiring will result in failure of heat exchanger

and cause dangerous operation.

• Do not allow minimum supply pressure to vary downward.

Doing so will decrease input to furnace. Refer to Table 2for

Gas supply and manifold pressures.

manifold.

10. Replace combustion air box cover.

11. Return fourth (4th) DIP switch to previous setting.

Natural Gas Input Rating Check

NOTE: The gas meter can be used to measure input to furnace.

Rating is based on a natural gas BTU content of 1,000 BTU's per

cubic meter. Check with gas supplier for actual BTU content.

1. Make sure combustion air box cover is in place and closed

before performing the following steps.

2. Turn OFF gas supply to all appliances and start furnace.

Use jumper wire on R to W1 and W2 for Hi fire.

3. Time how many seconds it takes the smallest dial on the

gas meter to make one complete revolution. Refer to Ex-

ample.

4. Repeat steps 2 and 3 with jumper wire on R to Wl for low

fire. NOTE: Fourth (4th) DIP switch must be in on position.

(See furnace wiring diagram). Return fourth (4th) DIP

switch to previous setting after check.

NOTE: If meter uses a 2 cubic foot dial, divide results (seconds) by

two.

5. Relight all appliances and ensure all pilots are operating.

Orifice Sizing

NOTE: Factory sized orifices for natural and LP gas are listed in

the furnace Technical Support manual.

Ensure furnace is equipped with the correct main burner orifices.

Refer to Table 3 &Table 4 for correct orifice size for a given heat-

ing value and specific gravity for natural and propane gas.

Operation Above 2000' Altitude

Fire, Explosion, Poison carbon monoxide gas hazard.

This conversion shall be done by a qualified service

agency in accordance with the Manufacturer's

instructions and all applicable codes and require-

ments, or in the absence of local codes, the applicable

national codes.

Failure to follow these instructions exactly can result in

death, personal injury and/or property damage.

These units may be used at full input rating when installed at alti-

tudes up to 2000'. When installed above 2000', the high fire input

must be decreased 2% (natural) or 4% (LP) for each 1000' above

sea level. This may be accomplished by a simple adjustment of

manifold pressure or an orifice change, or a combination of a pres-

sure adjustment and an orifice change. The changes required de-

pend on the installation altitude and the heating value of the fuel.

Table 3 & Table 4 showthe proper furnace manifold pressure and

gas orifice size to achieve proper performance based on elevation

above sea level for both natural gas and propane.

To use the natural gas table, first consult your local gas utility for

the heating value of the gas supply. Select the heating value on the

vertical border and follow across the table until the appropriate

elevation for the installation is reached. The first value in the box at

the intersection of the heating value and elevation will be the man-

ifold pressure required. If a gas orifice change is also required, the

box is shaded. The required orifice size is shown at the bottom of

the table.

8. Reassemble all parts in reverse order as removed. Be sure

to engage the main burner orifices in the proper opening in

the burners.

9. After reassembling, turn gas on and check all joints for gas

leaks using a soapy solution. All leaks must be repaired im-

mediately.

Gas Piping Requirements

1. Install gas piping in accordance with local codes, or in the

absence of local codes, the applicable national codes.

2. It is recommended that a manual shutoff valve be installed

in the gas supply line outside the unit. Locate valve as close

to the furnace as possible where it is readily accessible. Re-

fer to Figure 10.

Typical Gas Piping

25-22-31

3. Use black iron or steel pipe and fittings or other pipe ap-

proved by local code.

4. Use pipe thread compound which is resistant to natural and

LP gases.

5. Install a dripleg no less than 3" long totrap dirt and moisture

before it can enter gas valve.

6. Provide a 118" inch plug for test gauge connection immedi-

ately up stream of gas supply connection to furnace.

7. Use two pipe wrenches when making connections to pre-

vent gas valve from turning.

8. Flexible corrugated metal gas connector may NOT be used

inside the furnace or be secured or supported by the fur-

nace or ductwork.

9. Properly size gas pipe to handle combined appliance load

or run gas pipe directly from gas meter or LP gas regulator.

10. Install correct pipe size for run length and furnace rating.

11. Measure pipe length from gas meter or LP second stage

regulator.

Fire or explosion hazard.

Gas connector must be properly installed, cannot go

through the side of the furnace, and can not be used

inside the furnace.

Failure to properly install gas connector can result in

death, bodily injury and/or property damage.

Additional LP Piping Requirements

•Have a licensed LP gas dealer make all connections at stor-

age tank and check all connections from tank to furnace.

• If copper tubing is used, it MUST comply with limitation set

in Local Codes, or in the absence of local codes, the gas

codes of the country having jurisdiction. See Appendix.

•Two-stage regulation of LP gas is recommended.

Fire or explosion hazard.

Liquid petroleum (LP) gas is heavier than air and will

settle and remain in low areas and open depressions.

Thoroughly ventilate area and dissipate gas. Do NOT

use a match or open fla me to test for lea ks, or attempt to

start up furnace before thoroughly ventilating area.

An open flame or spark can result in death, personal

injury and/or property damage.

Final Check

• Test all pipe for leaks.

• If orifices where changed, make sure they are checked for

leaks.

• During pressure testing of gas piping system, observe the

following:

a. If test pressure does not exceed 1/2" PSIG, isolate the

furnace by closing its individual manual shutoff valve.

b. If test pressure exceeds 1/2" PSIG, the furnace and its in-

dividual shutoff valve must be disconnected from the gas

supply system.

• To check for leaks apply soap suds or a liquid detergent to

each joint. Bubbles forming indicate a leak.

• Do not use an open flame totest for gas leaks. Fire or explo-

sion could occur.

• Correct even the smallest leak at once.

441 01 2016 02 [_

7. Electrical Wiring

Electrical shock hazard.

Turn OFF electrical power at fuse box or service panel

before making any electrical connections and ensure a

proper ground connection is made before connecting

line voltage.

Failure to do so can result in death, personal injury

and/or property damage.

Power Supply Wiring

The furnace MUST be electrically wired and grounded in accor-

dance with local codes, or in the absence of local codes, the appli-

cable national codes.

Field wiring connections must be made inside the furnace connec-

tion box. A suitable strain relief should be used at the point the

wires exit the furnace casing.

Copper conductors shall be used. Line voltage wires should be

sized for the input amps stated on the rating plate. Furnace must

be connected to its own separate circuit.

Thermostat

The 2-stage furnace control will operate with either a single stage

or a two stage heating thermostat and will provide 2-stage heating

operation. For single stage thermostat installations, the R and W

wires from the thermostat connect to the R and Wl connections

on the furnace control. Note: The fourth (4th) DIP switch should

be in the off position for the furnace to operate properly with a

single stage thermostat. Failure to change DIP switch with single

stage thermostat will result in Low Fire operation ONLY. (See wir-

ing diagram) During operation, the furnace will operate on low fire

for 12 minutes. If the heat request exists for more than 12 minutes,

the furnace will automatically shift to the high fire mode for the re-

maining duration of the heating cycle. For 2-stage thermostat

installations, the R, Wl and W2 wires from the thermostat connect

to the R, Wl and W2 connections on the furnace control. During

operation, the furnace will shift from low fire to high fire as re-

quested by the thermostat. The thermostat heat anticipator should

be adjusted to a .10 setting for both types of thermostats.

Thermostat location has an important effect on the operation of

the unit. Follow instructions included with thermostat for correct

mounting and wiring.

Low voltage connections to furnace must be made on terminal

board to fan control.

Optional Equipment

All wiring from furnace to optional equipment MUST conform to lo-

cal codes or, in the absence of local codes, the applicable national

codes. Install wiring in accordance with manufacturer's instruc-

tions.

Humidifier/Electronic Air Cleaner

The furnace is wired for 115 VAC humidifier and/or electronic air

cleaner connection.

CAUTION

Do NOT exceed 115V/0.8 amp. maximum current load

for both the EAC terminal and the HUM terminal com-

bined.

NOTE: The humidifier will be powered when the furnace is fired

and the circulating air blower comes on. The electronic air cleaner

will be powered anytime the thermostat calls for air movement.

However, the electronic air cleaner is NOT energized during con-

tinuous fan operation controlled by the electronic fan control.

Dehumidification (NTV6NNE)

The fan control is wired for 24 VAC normally open (N/O) dehumi-

distat connection. Connect dehumidistat to the Rterminal and the

1/4" male quick connect Y2 terminal on the fan control (See

Figure 14 and "Furnace Wiring Diagram3 A 20% reduction of

cooling airflow will occur when the Y2 dehumidistat terminal is en-

ergized during a call for cooling from the thermostat.

The fan control is preset at the factory with an adjustable blower

ON delay of 30 seconds in the heating mode. The blower OFF tim-

ing is preset at 140 seconds. If desired, the fan ON delay and OFF

delay can be reset to obtain the longest delay times while still

maintaining comfort levels. See "Furnace Wiring Diagram".

NOTE: It is recommended to achieve maximum efficiency that the

fan control be set to turn on at 30 seconds after the burners light.

NOTE: For single stage thermostat operation the fourth (4th) DIP

switch must be in the off position. (See furnace wiring diagram and

8. Ductwork and Filter (NTV6/VNE &NTP6/TNE)

Poison carbon monoxide gas hazard.

Do NOT draw return air from inside a closet or utility

room where furnace is located. Return air duct MUST be

sealed to furnace casing.

Failure to properly seal duct can result in death and/or

personal injury.

Duct Connections

When a refrigeration coil is used in conjunction with this

unit, it must be installed on the discharge side of the unit to

avoid condensation on the heat exchanger.

If separate evaporator and blower unit is used, install good

sealing dampers for air flow control. Chilled air going

through the furnace could cause condensation and shorten

furnace life. Dampers (purchased locally) can be either au-

tomatic or manual. Manually operated dampers MUST be

equipped with a means to prevent furnace or air condition-

ing operation unless damper is in the full heat or cool posi-

tion.

This furnace may be installed in only a bottom or side return ap-

plication. Return air through the back of the unit is NOT allowed.

Side connections can be made by cutting out the embossed area

shown in Figure 15.

Cutting Side Return Air Opening

Starting

Hole

Bottom returns can be made by removing the knockout panel in

the furnace base. Do NOT remove knock-out except for a bottom

return.

Duct Design (NTV6NNE & NTP6/TTNE)

Design and install air distribution system to comply with Air Condi-

tioning Contractors of America manuals or other approved meth-

ods that conform to local codes and good trade practices.

When the furnace is located in an area near or adjacent to the liv-

ing area, the system should be carefully designed with returns to

minimize noise transmission through the return air grille. Any

blower moving a high volume of air will produce audible noise

which could be objectionable when the unit is located very close to

a living area. It is often advisable to routethe return air ducts under

the floor or through the attic.

• Refer to furnace Technical Support Manual (Blower Data)

for air flow information.

• Size ductwork to handle air flow for heating and air condi-

tioning.

Duct Installation Requirements

• When furnace supply ducts carry air outside furnace area,

seal return air duct to furnace casing and terminate duct

outside furnace space.

Poison carbon monoxide gas hazard.

Cool air passing over heat exchanger can cause

condensate to form resulting in heat exchanger failure.

This could result in death and/or personal injury.

• Installation of locking-type dampers are recommended in

all branches, or in individual ducts to balance system's air

flow.

• Non-combustible, flexible duct connectors are recom-

mended for return and supply connections to furnace.

• If air return grille is located close to the fan inlet, install at

least one, 90 ° air turn between fan and inlet grille to reduce

noise.

• Ductwork installed in attic, or exposed to outside tempera-

tures require 2" of insulation with outdoor type vapor barri-

er.

• Ductwork installed in an indoor unconditioned space re-

quires a minimum of 1" of insulation with indoor type vapor

barrier.

Inspection Panel on some models

A removal access panel should be provided in the outlet duct

when the furnace is installed without a cooling coil. This will allow

smoke or reflected light to be observable inside the casing to indi-

cate the presence of leaks in the heat exchanger. This access cov-

er shall be attached in such a manner as to prevent air leaks.

Filters

A filter MUST be used. Filters may not be supplied with all models,

but can be purchased from your dealer.

The furnaces, with 1600 or less CFM rating, are supplied with a

16" x 25" high velocity filter and rack. On these models, the sup-

plied filter rack may be mounted internally for bottom return or ex-

ternally for side return.

The furnaces with greater than 1600 CFM requires that both left

and right side returns are used in side return applications. Two 16"

x 25" high velocity filters and racks are provided with furnace. Fil-

ter racks must be mounted externally. If return air must be on one

side only, an optional 20"x 25" filter standoff rack kits can be used.

(See Figure 16) For bottom return, an optional 20" x 25" filter rack

kit can be mounted internally.

Sub-Bases for Combustible Floors -Furnace Only

The Subbase for Combustible Floors MUST be used when a

downflow furnace is set on combustible material even when the

furnace is installed on a coil box (cased coil).

NOTE: Supply opening is 37/8" from the rear of the furnace.

Therefore maintain a 37/8" clearance from a wall behind the fur-

nace (where applicable).

1. Cut the opening in the floor according to Table 5. The hole in

the floor must be cut to the dimensions listed in Table 5 since

the base is equipped with locating tabs that center the base

over the opening.

Ductwork and Filter (Downflow/Horizontal) on NDP6/TDE

The opening in the base is 11/4"(32mm) shorter and 11/8"(29mm)

narrower than the minimum required size of the opening in the

floor. This is done to maintain a 1" clearance between the floor and

the plenum.

2. Fabricate the plenum to the dimensions given in Table 5.

bustible flooring.

NOTE: Supply opening is 37/8" from the rear of the furnace.

Therefore maintain a 37/8 ', clearance from wall (where applica-

ble).

1. Cut the opening in the floor according to Table 6. The hole in

the floor must be cut to the dimensions listed in Table 6 since

the base is equipped with locating tabs that center the base

over the opening.

The opening in the base is 11/4"(32mm) shorter and 1 1/8" (29mm)

narrower than the recommended size of the opening in the floor.

This is done to provide a 1" clearance between the floor and the

plenum.

2. Fabricate the plenum to the dimensions given in Table 6.

Note that the dimensions given are outside dimensions.

Non-Combustible Floor:

Set the furnace over the opening in the floor. If necessary, grout

around the base to seal air leaks between the base and the floor.

Filters:

The filters supplied with the furnace may be installed in the return

air plenum above the furnace. A filter rack is supplied with each

furnace. See Figure 24.

NOTE: The return air plenum MUST extend a sufficient height

above dimension "A" (Figure 25) to provide for the attachment of

a return air duct or grille above the filters.

NOTE: The furnace is provided with high velocity type filter(s).

The size, quantity, and type of filter supplied with the furnace will

handle the airflow required if central air conditioning is used with

the furnace.

Insert end of filter rack with /4' (19ram) flange into slot in the

back of the unit. See Figure 24.

With filter rack pushed back, insert front end with 1/4" (6mm)

flange into position and push into front slot. with filter rack

pushed as far forward as it will go, bend 1/4" (6mm) flange and

3/4"(19mm) flange up 90 degrees. See Figure 24.

NOTE: Plenum must be fitted as close to the return air flange of the

unit as possible to eliminate any air bypassing the filters.

3. Filters can only be installed through the right hand side of the

unit blower opening. Slide filter into unit until it is in position to

be pushed up and over into place on the left hand side of unit.

See Figure 25.

441 01 2016 02

CAUTION

If any sparks, odors or unusual noises occur, immediately

shut OFF power to furnace. Check for wiring errors or ob-

struction to blower.

Gas Supply Pressure

Gas supply pressure should be within minimum and maximum

values listed on rating plate. Pressures are usually set by gas sup-

pliers.

(See L.P. Kit instruction manual for furnaces converted to L.R gas)

Adjust Pilot Burner

The furnace has a pilot flame to light the main burner. The flame

should surround 3/8" to 1/2" of the flame rod. See Figure 26. To ad-

just, remove cap from pilot adjusting screw on gas valve. Turn

screw counterclockwise to increase or clockwise to decrease

flame as required. Replace cap after adjusting screw.

Place thermometers in supply and return air registers as

close to furnace as possible, avoiding direct radiant heat

from heat exchangers.

Operate furnace on high fire for 10 minutes with all the reg-

isters and duct dampers open by using a jumper wire on R

to Wl and W2 thermostat connections on the fan board.

Note: The fourth (4th) DIP Switch should be in the on posi-

tion. (See furnace wiring diagram)

3. Take readings and compare with range specified on rating

plate.

4. If the temperature rise is not in the correct range, the blower

speed must be changed. A higher blower speed will lower

the temperature rise. A lower blower speed will increase the

temperature rise.

5. Repeat steps 2 thru 4 with the furnace operating on low fire

for 10 minutes by using a jumper wire on the R to W1 ther-

mostat connections on the fan board.

6, Remove the jumper wire after the adjustments are com-

plete. Return fourth (4th) to previous setting.

Main Burner Flame Check

Allow the furnace to run approximately 10 minutes then inspect

the main burner and pilot flames. See Figure 27.

Check for the following (Figure 27):

• Stable and blue flames. Dust may cause orange tips or

wisps of yellow, but flames MUST NOT have solid, yel-

low tips.

• Flames extending directly from burner into heat ex-

changer.

• Flames do NOT touch sides of heat exchanger

If any problems with main burner flames are noted, it may be nec-

essary to adjust gas pressures, or check for drafts.

Since the manufacturer cannot establish the static pressure

that will be applied to the unit, it is the responsibility of the

installer dealer/contractor to select the proper blower

speeds for the application when the unit is installed.

If it is necessary to change speeds, refer to steps below.

1. Refer to Furnace Wiring Diagram for location of the heating

and cooling speed taps located on the electronic fan control

as well as location of unused blower motor speed leads. Use

the chart (Table 6) to determine the blower motor speed set-

tings.

Temperature Rise Check

The blower speed MUST be set to give the correct air temperature

rise through the furnace as marked on the rating plate. Tempera-

ture rise is the difference between supply and return air tempera-

tures.

To check temperature rise,use the following procedure:

2, Change the heat or cool blower motor speed by removing the

motor lead from the "Heat" or "Cool" terminal and replace it

with the desired motor speed lead from the "Unused Motor

Lead" location. Connect the wire previously removed from

the "Heat" or "Cool" terminal to the vacated "Unused Motor

Lead" terminal.

3, If the same speed must be used for both heating and cooling,

remove the undesired motor speed lead from the "Heat" or

"Cool" terminal and connect that lead to the open terminal at

"Unused Motor Lead" location or tape off. Attach a jumper

between the "Heat" and "Cool" terminals and the remaining

motor speed lead.

Continuous Fan Operation

A terminal is provided on the electronic fan control located in the

circulating blower compartment for operation of the continuous

fan option. This connection is intended for the low speed motor

tap, and has a lower contact rating (8 amps) than the heat and cool

taps. When the low speed blower lead is connected to this termi-

Turn OFF power to furnace before changing speed taps.

Failure to do so can result in death and/or personal injury.

nal, this will provide low speed blower operation whenever the oth-

er two speeds (Heat or Cool) are not energized.

Heating and Continuous Blower Speed the Same

If it is necessary to operate the heating speed and continuous

blower speed using the same blower speed, connect a jumper be-

tween the "Heat" and "Cont" terminals on the electronic fan con-

trol.

Note: There should be only ONE motor lead going to the "Heat"

and "Cont" terminals.

Note: The blower speeds that the manufacturer sets from the fac-

tory for this product a re based on a nominal 400 C FM per ton cool-

ing and the mid range on the temperature rise for heating.

Since the manufacturer cannot establish the static pressure

that will be applied to the unit, it is the responsibility of the

installer dealer/contractor to select the proper blower

speeds for the application when the unit is installed.

If it is necessary to change speeds, refer to steps below.

1. The 115 VAC power supply to the furnace must be turned

OFF before making adjustments to the motor.

2, The heating, cooling and continuous blower speeds can be

adjusted by changing the switch settings that are located on

the motor control (see Figure 28). Switches #1 and #2 ad-

just the continuous blower speeds. Switches #3, #4 and #5

adjust the heating speeds. Switches #6, #7 and #8 adjust

the cooling speed. See the" Technical Support Manual"for

the switch settings for the desired airflow rates for the instal-

lation.

11. Furnace Maintenance

CAUTION

It is recommended that the furnace be inspected and serv-

iced on an annual basis (before the heating season) by a

qualified service technician.

See "User's Information Manual".

12. Sequence of Operation & Diagnostics for NTV6/VNE

The following is the normal operating sequence for the 2-stage control system.

Cooling (Y) Request:

24 VAC signals applied to Y &G terminals of EFT (electronic fan timer) control.

• Cool motor speed energized after 5 second Cool Fan On Delay time.

441 01 2016 02

Y & G signals removed from EFT.

• Cool motor speed de-energized after 60 second Cool Fan Off Delay time.

Cooling (Y) and dehumidification (Y2) requests: (Variable Speed ONLY)

• 24 VAC signals applied to Y, Y2 & G terminals of EFT (electronic fan timer) control.

• Same operation as the cooling (Y) request, except the cooling speed is reduced 20% to compensate for high humidity conditions

during cooling operation. The cooling speed returns to the normal setting after the Y2 signal is removed.

Circulating Fan (G) Request:

24 VAC signals applied to G terminals of EFT control.

• Low motor speed energized without delay.

G signal removed from EFT.

• Low motor speed de-energized without delay.

NOTE1) Furnaces with DC blower motors run a low circulating fan speed in response to G request.

NOTE2) Furnaces with PSC blower motors de-energize the Low Heat fan speed during the heat exchanger warm-up period on a

call for Heating that occurs during a G request.

NOTE3) Heating or Cooling requests received during a Fan request cause the fan speed to change to the appropriate heat or cool

speed after the selected Fan On Delay time expires. The fan returns to circulating speed after the selected Fan Off Delay time expires

following loss of the Heating or Cooling request.

Heating (W1) Request (single stage thermostat operation, 4th DIP switch on fan timer, must be in off position)

(see furnace wiring diagram):

24 VAC signals applied to Wl terminal of EFT control.

• Inducer motor turns on at high speed.

• The high fire solenoid energizes.

• Following a 3 second prepurge delay, the pilot valve opens and the ignitor begins to warm up.

• After the pilot lights, the main burners energize and light (burners now at high fire rate).

• Timed from the opening of the main gas valve, the control will delay the selected Heat Fan On Delay time before switching the

inducer to low speed, de-energizing the high fire solenoid and the fan switches to Low Heat speed.

• Timed from initial application of the Heating request, if the Wl request is still present after the Low Fire Delay time expires

(12 minutes), the inducer switches to high speed, the high fire solenoid energizes and the fan switches to High Heat speed.

Wl signal removed from EFT.

• The gas valve de-energizes and the main burners go out.

• The inducer runs at its present speed for a 5 second postpurge period.

• The fan switches to (or stays at) Low Heat speed.

• Timed from the gas valve de-energizing, the Low Heat fan speed de-energizes after the selected Heat Fan Delay time expires.

NOTE4) If a new Heating request arrives while the control is waiting in the Heat Fan Off Delay time, the fan speed switches to High

Heat until the Heat Fan Off Delay expires or the Heat Fan On Delay expires for the new Heating request.

Heating Request (two stage thermostat operation, 4th DIP switch must be in on position) (see furnace wiring

diagram):

24 VAC signals applied to Wl terminal of EFT control.

• Same response as single stage thermostat operation described above except the control will not go to high fire, High Heat fan

speed unless a W2 signal is applied.

24 VAC signals applied to Wl and W2 terminals of EFT control.

• Same light-off routine as described for the signal stage thermostat operation except that at the end of the selected Heat Fan On

Delay, the inducer remains on high fire, the high fire solenoid remains energized and the High Heat fan speed energizes.

NOTE5) The EFT control responds without delay to the presence or loss of W2 (with Wl constant). Wl & W2 results in high inducer,

high fire and High Heat fan speed. Wl only results in low inducer, low fire and Low Heat fan speed.

Heating Request with Gas Supply Line Shut Off:

24 VAC signals applied to Wl terminal of EFT control.

• Inducer motor turns on at high speed.

• The high fire solenoid energizes.

• Following a 3 second prepurge delay, the pilot valve opens and the

igniter begins to warm up.

• The igniter glows red-hot for 30 seconds, then turns off.
