TO WHOM IT MAY CONCERN:

The new Raypak series RP2100 pool heaters have been designed to eliminate

the need for conventional heat sinks (high temperature piping). The initial

connection to the heater is made with a 2" PVC union adapter to which PVC

may then be connected with appropriate cement.

This newly authorized piping arrangement is described in the installation

manual provided by Raypak, and has been successfully tested by Raypak to

assure its acceptability.

AFTER START-UP

Feel the inlet and outlet pipes. Outlet pipe should be

only slightly warmer than the inlet. It should not be hot.

WARNING: Should overheating occur or the gas

supply fail to shut off, turn off the manual gas control to

the appliance.

VISUAL INSPECTION

With the heater on, remove the door and make a

visual check of the pilot and burner.

The flame should be blue with a well-defined

pattern.

4" MAX

Fig. # 8205.2

MAIN BURNER FLAME

Fig. # 8964.1

PILOT BURNER FLAME

A yellow or "floating" flame indicates restricted air

openings or incorrect orifice size. Should this occur,

shut the heater off and contact your installer or gas

supplier.

WATER PRESSURE SWITCH

A water pressure switch is provided in the heater to

shut off the burners in the event that water supply to the

heater is interrupted. It is very important to verify that

the switch electrically opens and shuts off the gas valve

when water flow to the heater is interrupted. Otherwise,

rapid and severe damage will likely occur to the heater.

(The water pressure switch should be checked and

adjusted for proper operation by a qualified service

person at the time of installation and periodically

checked thereafter. Refer to pressure switch servicing

instruction in Section 4 of this manual).

WARNING: Operation of the heater without water circu-

lation will cause rapid and severe damage to the heater.

SECTION 2/CAUTION

Elevated water temperature can be hazardous, and

the U. S. Consumer Product Safety Commission rec-

ommends the following guidelines:

1. Spa or hot tub water temperatures should never

exceed 104°F (40°C). A temperature of 100°F (38°C)

is considered safe for a healthy adult. Special

caution is suggested for young children.

2. Drinking of alcoholic beverages before or during spa

or hot tub use can cause drowsiness which could

lead to unconsciousness and subsequently result in

drowning.

3. Pregnant Women Beware! Soaking in water over

102°F (39°C) can cause fetal damage during the first

three months of pregnancy resulting in the birth of a

brain-damaged or deformed child. Pregnant women

should stick to the 100°F (38°C) maximum rule.

4. Before entering the spa or hot tub, users should

check the water temperature with an accurate ther-

mometer; spa or hot tub thermostats may err in

regulating water temperatures by as much as 4°F

(2.2°C).

5. Persons with a medical history of heart disease,

circulatory problems, diabetes, or blood pressure

problems should obtain a physician's advice before

using pools or hot tubs.

6. Persons taking medications which induce drowsi-

ness, such as tranquilizers, antihistamines, or anti-

coagulant, should not use spas or hot tubs.

SECTION 3/MAINTENANCE AND

CARE PROCEDURES

To be followed one month after start-up and then

semi-annually.

1. Inspect top of heater and drafthood for soot, a sticky

black substance around finned tubes and "V"

baffles), and open flue gas passage ways. Any visible

soot should be cleaned for proper operation.

CAUTION: Soot may be combustible. Wet sooted

surfaces completely prior to cleaning. Do not use steel

wire brush.

2. Clean main burners and pilot burner of dust and lint.

3. Inspect and operate all controls, gas valve and

pressure relief valve.

4. Make visual check of the burner and pilot flame.

Flame pattern on the main burner and pilot is indi-

cated in the previous illustration. Yellow flame

means restriction of the air openings. Lifting or

blowing flame indicates high gas pressure. Low

flame means low gas pressure. Should this occur,

shut the heater off and contact your gas supplier or

qualified service agency.

5. On indoor heaters, clean room intake openings to

assure adequate flow of combustion and ventilation

air.

CAUTION: Combustion air must not be contaminated by

corrosive chemical fumes which can damage the heater

and void the warranty.

6. Keep area around heater clear and free from combus-

tible materials, gasoline and other flammable and

corrosive vapors and liquids.

BASIC TIPS IF HEATER WILL NOT FIRE:

1. If you have no electrical power; it may be your "circuit

breakers" have tripped. Try re-setting them.

2 If you have electrical power but the heater will not fire

check the following:

3. The time clock must be moved to the "ON" position.

4. Your pump strainer basket may be full. If so remove

debris.

5. Your filter may be dirty. If so, backwash or clean

filter. (To tell if your filter is dirty, look to see if the

filter pressure will be higher than usual).

6. The pump may have lost it's prime. It may be run-

ning dry, check the pressure on the filter. If there is

no pressure; then you are not moving water (or your

gauge is broken). Try to get the pump to run at it's

normal flow rate.

POOL & SPA WATER CHEMISTRY

Chemical imbalance can cause severe damage to

your heater and associated equipment. Maintain your

water pH between 7.4 and 7.8 and total alkalinity between

100 and 150 p.p.m. If the mineral content and dissolved

solids in the water become too high, scale forms inside

the heat exchanger tubes, reducing heater efficiency and

also damaging the heater. If the pH drops below 7.2, the

heater will be severely damaged. This will result in

corrosion of the heat exchanger. Heat exchanger

damage resulting from chemical imbalance is not

covered by the warranty.

AUTOMATIC CHLORINATORS AND CHEMICAL FEED-

ERS

All chemicals must be introduced and completely

diluted into the pool or spa water before being circulated

through the heater. Do not place chlorine tablets or

bromine sticks in the skimmer. High chemical concen-

trations will result when the pump is not running (i.e.

overnight).

Chlorinators must feed downstream of the heater and

have an anti-siphoning device to prevent chemical back-

up into the heater when the pump is shut off.

NOTE: High chemical concentrates from feeders and

chlorinators that are out of adjustment will cause very

rapid corrosion to the heat exchanger. Such damage is

not covered under the warranty.

COLD WEATHER OPERATION

MODERATE CLIMATE: Heater operation can continue

during short term cold spells. When temperatures are

below freezing, flow (continuous pump operation) must

be maintained.

CAUTION: Do not use the heater to maintain water

temperatures just above freezing or for freeze protection.

When heater is used during freezing weather, care must

be taken to avoid freeze ups. Continuous pump opera-

tion is a must. Additional protection may be required.

The heater is not warranted against freeze ups.

COLD CLIMATE: Prolonged operation with water tem-

peratures below 50°F is not recommended. When

starting the heater with pool temperatures below 50°F

operate the heater continuously until higher tempera-

tures are reached. Operating the heater for prolonged

periods with pool water below 50°F can seriously damage

the heater, and is not covered by the warranty.

For cold climate areas, please follow the winterizing

procedures listed.

WINTERIZING THE POOL & SPA HEATER

When heaters installed outdoors in freezing climate

areas are to be shut down for the winter, observe the

following step-by-step procedure:

1. Turn off gas valve, manual gas valve, and

electrical supply to the heater.

2. Open drain plug located on the inlet/outlet

header, (under water pipes). Remove the heat

exchanger inspection panel on the side op-

posite water piping to gain access to the drain

plug on the return header. Open drain plug on

return header.

SECTION 3 / INSTALLATION INSTRUCTIONS

IMPORTANT NOTICE

These instructions are intended for the use of quali-

fied personnel only, specifically trained and experienced

in the installation of this type of heating equipment and

related system components. Installation and service

personnel may be required by some states to be licensed.

If your state is such, be sure your contractor bears the

appropriate license. Persons not qualified shall not

attempt to fix this equipment nor attempt repairs accord-

ing to these instructions.

WARNING:

Improper installation, adjustment, alteration, ser-

vice or maintenance may damage the equipment,

create a hazard resulting in asphyxiation, explosion or

fire, and will void the warranty.

CODE REQUIREMENTS

NOTE: The heater should not be located in an area

where possible water leakage will result in damage to

the area adjacent to the appliance or to the structure.

When such locations cannot be avoided, it is recom-

mended that a suitable drain pan, adequately drained,

be installed under the appliance. The pan must not

restrict combustion air flow.

Installation must be in accordance with local codes,

or, in the absence of local codes, with the latest edition

of the National Fuel Gas Code, ANSI Z223.1 and National

Electrical Code, ANSI/NFPA 70, and for Canada, the

latest edition of CAN/CGA-B149.1 and B149.2, and

Canadian Electrical Code, CSA C22.1 Part 1 and Part

BASE INSTALLATION

Heater must be mounted on a level base, such as

cement slab, cement blocks or other non-combustible

surface. An optional non-combustible base is available

for all models. An alternative method for providing a base

for combustible floors is illustrated below. Heaters must

not be installed on carpeting.

Fig. # 8148.1

Utilize hollow concrete cinder blocks, align holes and

leave ends open.

CLEARANCES

ALL HEATERS

For clearances from combustible surfaces, see the

chart below.

CLEARANCE FROM COMBUSTIBLE CONSTRUCTION

INDOOR INSTALLATIONS:

Top*(Drafthood) - 30" Back - 6"

Front - Alcove Right Side-(Water Side) 12"

Vent - 6" Left Side-(Opposite Water

side) 6"

OUTDOOR INSTALLATION:

Top* (Stackless top or outdoor stack) - Unobstructed

Back - 6"

Side - 6"

*Clearance from top of vent terminal.

When installed according to the listed minimum

clearances from combustible construction materials, the

Raypak pool heaters can still be serviced without remov-

ing permanent structural construction around the heater.

However for ease of servicing, we recommend a

clearance of at least 24" in the front, and at least 18" on

the water connection side. This will enable the heater to

be serviced in its installed location, that is, without

movement or removal of the heater.

Clearances less than these (6" minimum), may

require removal of the heater to service either the heat

exchanger or the burner tray. In either case, the heater

must be installed in a manner that will enable the heater

to be serviced without removing any structure around the

heater.

OUTDOOR HEATERS

These heaters are design certified for outdoor

installation, when equipped with the approved tops des-

ignated for outdoor use.

WARNING: The heater shall not be located in an area

where water sprinklers, or other devices, may cause

water to spray through the cabinet louvers and into the

heater. This could cause internal rusting or damage

some electrical components, and this would void the

warranty.

WARNING: Do not install within 3 feet of a heat pump or

an outdoor condensing unit. Strong air intake from these

equipment can disturb the combustion process and

cause damage or personal injury.

Heaters must not be installed under an overhang of less than three (3) feet from the top of the heater. Three

(3) sides must be open in the area under the overhang. Roof water drainage must be diverted away from the

heaters installed under overhangs with the use of gutters.

For U.S. installations,the point from where the flue products exit the heater must be a minimum of four (4) feet

below, four (4) feet horizontally from, or one (1) foot above any door, window or gravity inlet into any building. The

top surface of the heater shall be at least three (3) feet above any forced air inlet, or intake ducts located within ten

(10) feet horizontally.

For installations in Canada, pool heaters shall not be installed with the top of the vent assembly within 10 feet

below, or to either side, of any opening into the building. Refer to the latest revisions of CAN/CGA-B149.1 and B149.2.

outlined in the latest edition of the National Fuel Gas

Code, ANSI Z2231(Canada-CAN/CGA-B149.1 and

B149.2) and any local codes that may have jurisdiction.

CAUTION: Combustion air must not be contaminated

by corrosive chemical fumes which can damage the

heater and void the warranty.

*Designation for Propane is "EP", Natural gas is "EN". Prefix "C" is for Cast Iron (ASME) Headers; "P" is for Plastic (Capron)

Headers. Above input ratings are per A.G.A. specifications. Reduce input 4% for each 1000 ft. above sea level when installed above

Note: Plastic (Capron) Headers cannot be used for ASME installations.

VENT PIPING

WARNING:

Indoor boilers require a drafthood that must be

connected to a vent pipe and properly vented to the

outside. Failure to follow this procedure can cause fire

or fatal carbon monoxide poisoning.

Vent piping the same size as the draft hood outlet is

recommended, however, when the total vent height is at

least ten (10) feet (draft hood relief opening to vent

terminal), the vent pipe size may be reduced as speci-

fied in Chapter 10 of the National Fuel Gas Code, ANSI

Z 223.1. (Canada-CAN/CGA-B149.1 and B149.2) As

much as possible avoid long horizontal runs of vent pipe

and too many elbows. If installation requires horizontal

non-vertical runs, the vent pipe must have a minimum of

1/4 inch per foot rise and should be supported at not less

than five foot intervals. Plumbers tape, criss-crossed, will

serve to space both horizontal and vertical piping. Gas

vents supported only by the flashing and extending above

the roof more than five feet should be securely guyed or

braced to withstand snow and wind loads. We recom-

mend use of insulated vent pipe spacer through the roofs

and walls. Another option for installation that requires

horizontal runs is using the D-2 powervent kit option. The

powervent is certified for catagory III venting up to 40 ft.

equivalent 4" diameter venting.

For protection against rain or blockage by snow, the

vent pipe must terminate with a vent cap which complies

with the local codes or, in the absence of such codes, to

the latest edition of the National Fuel Gas Code, ANSI

Z223.1. (Canada-CAN/CGA-B149.1 and B149.2)

The discharge opening must be a minimum of two feet

vertically from the roof surface and at least two feet

higher than any part of the building within ten feet. Vent

stack shall be at least five feet in vertical height above

the drafthood outlet. The vent cap location shall have a

minimum clearance of 4 feet horizontally from, and in no

case below, unless a 4-foot horizontal distance is main-

tained, from electric meters, gas meters regulators and

relief equipment.

The weight of the vent stack or chimney must not

rest on heater draft hood. Support must be provided in

compliance with applicable codes. The heater top and

draft hood must be readily removable for maintenance

and inspection. Vent pipe should be adequately sup-

ported to maintain proper clearances from combustible

construction.

Type "B" double wall or equivalent vent pipe is

recommended. However single wall metal vent pipe

may be used as specified in the latest edition of the

National Flue Gas Code ANSI Z 223.1. (Canada-CAN/

CGA-B149.1 and B149.2)

Fig. #RP 8119.2

GAS SUPPLY CONNECTIONS

Gas piping must have a sediment trap ahead of the

heater gas controls, and a manual shut-off valve located

outside the heater jacket. All gas piping should be

tested after installation in accordance with local codes.

CAUTION: The heater and its manual shut off valve

must be disconnected from the gas supply during any

pressure testing of that system at test pressures in

excess of 1/2 psig (3.45 KPA). Dissipate test pressure

in the gas supply line before reconnecting the heater

and its manual shut off valve to gas supply line. FAIL-

URE TO FOLLOW THIS PROCEDURE MAY DAMAGE

THE GAS VALVE. OVER PRESSURED GAS VALVES

ARE NOT COVERED BY WARRANTY. The heater and

its gas connections shall be leak tested before placing

the appliance in operation. Use soapy water for leak

test. DO NOT use open flame.

Fig. # 8149

NOTE: Do not use teflon tape on gas line pipe thread. A

flexible sealant is recommended.

A minimum of 7" W.C. and a maximum of 14" W.C.

upstream pressure under load, and no load conditions

must be provided for natural gas or a minimum of 12"

W.C. and a maximum of 14" for propane gas.

GAS PRESSURE REGULATOR

The gas pressure regulator is preset at 4" W. C. for

natural gas, and 11" W. C. for propane gas. The pressure

at the gas valve, taken with a manometer, should be about

3.7" W. C. natural gas (3.9" W.C. for Low NOx) and 10.5"

W. C. propane gas. If an adjustment is needed, remove

seal and turn adjustment screw clockwise to

increase pressure or counter-clockwise to

decrease pressure.

PIPE SIZING FOR GAS CONNECTIONS

Low NOx units are not available in propane.

PLUMBING FOR WATER CONNECTIONS

LOCATION

The RP 2100 heater requires water flow and positive

pressure to fire and operate properly. It must therefore

be installed downstream of the discharge side of the filter

pump. A typical installation is plumbed as follows:

1. The inlet side of the filter is plumbed directly to the

discharge side of the filter pump;

2. The outlet side of the filter is then plumbed to the inlet

of the heater; and

3. The outlet of the heater is plumbed to the return line

to the pool or spa. The pump, filter and heater are

thus plumbed in series.

CONNECTIONS

Before attaching the 2-inch unions to the inlet/outlet

header, make sure the o-rings are properly seated in the

grooves. Use AquaLube or equivalent non-petroleum

based lubricant on the o-ring. Tighten the unions hand

tight. Glue PVC piping directly to the unions.

UNITHERM GOVERNOR OPERATION

The patented Unitherm Governor is a thermostatic

mixing valve specifically designed to maintain constant

heater internal temperature between 105° to 115°F

despite continually changing flow rates from the filter

and changing pool temperatures. This narrow range is

needed to prevent damaging condensation on the burn-

ers which will occur if the heater runs for any length of

time below 100°F. It is also needed to inhibit scale

formation in the tubes by maintaining temperatures

well below accelerated scaling temperatures.

INTERNAL AUTOMATIC BY-PASS VALVE

In addition to the Unitherm Governor, a built-in

automatic by-pass valve is provided in the in/out

header. While the Unitherm Governor responds to the

changes in water temperature in the heater, the internal

by-pass valve automatically responds to changes in

water pressure in the piping system. Proper amount of

water flow is maintained through the heater under

varying pressures dictated by the conditions of the

pump and filter.

Fig.#2003

EXTERNAL AUXILIARY BYPASS VALVE

(Where Required)

An auxiliary bypass valve should be used when flow

rates exceed 125 GPM (usually a high performance

pump size larger than two horsepower will exceed this

flow rate). This valve is required to complement the

function of the automatic bypass valve, particularly

when starting the heater in winter or early spring when

the spa or pool temperature is down below 50°F. It also

serves to eliminate needless pressure drop through the

heater and accompanying reduction in the flow rate to

the spa jets, etc.

AUXILIARY BYPASS VALVE ADJUSTMENT

To set bypass: With clean filter, adjustment is made

by feeling the inlet and outlet pipes at the heater. Outlet

pipes should be slightly warmer than inlet and comfort-

able to the touch. If pipe is hot, close bypass; if cold,

open bypass.

Plumbing from the heater back to the pool must not have

any valves or restriction that could prevent flow when the

pump is operating.

CAUTION: A source of additional heated water, i.e. solar

systems, must be connected to the heater outlet pipe. If

this is connected to the heater inlet, incorrect pool water

temperature readings will be displayed on the heater

control panel.

PRESSURE RELIEF VALVE INSTALLATION

To conform to local building codes, it may be

necessary to install a pressure relief valve. A 3/4"

pressure relief valve having a capacity equal to BTU/HR

output of the model to be installed is recommended for

this appliance. The maximum acceptable pressure re-

lief valve setting is 125 psi.

A 3/4" NPT connection is provided in the inlet/outlet

header for installation of a pressure relief valve. The

valve shall be installed in a vertical position. Do not over

tighten. Install pressure relief valve hand tight plus 1/2

turn.

NOTE: To avoid water damage or scalding due to valve

operation, drain pipe must be connected to valve outlet

and run to a safe place of discharge. Drain pipe must be

the same size as the valve discharge connection

throughout its entire length and must pitch downward

from the valve. No shutoff valve shall be installed

between the relief valve and the drain line. Valve lever

should be tripped at least once a year to ensure that

waterways are clear.

Repeating the process will return the board to "FFF"

which is Fahrenheit.

RP2100 REMOTE CONTROL INSTALLATION

CAUTION: Before installing remote controls to the

RP2100 Digital Heater, read the following:

The Raypak RP 2100 Digital Heater is remote ready in

most cases. The digital liquid crystal (LCD) display

shows the actual pool temperature, operating status,

and service codes (See examples below). The touch

pad on the control panel allows you to select the desired

pool or spa temperature. It also indicates when a remote

system is controlling the heater by displaying REM in

the display. When connecting the RP2100 Digital to a

remote system, identify whether it is a two or three wire

remote system. Select the appropriate instruction listed

below to properly install the remote to the heater.

Important Installation Notes for

Remote or external wiring configuration

• Remote wiring must be run in separate conduit.

• Remote wiring must not be run parallel to High Voltage

lines.

• For runs of under 30 feet, remote wiring should have

stranded conductors with a minimum of 22 AWG,

600V, cable twisting 1.5 to 2.5 and jacketed.

• For runs over 30 feet, the conductors should be a

minimum of 20 AWG, 600V, cable twisting 1.5 to 2.5

inch lay that is shielded and jacketed.

• Maximum cable length of 200 feet.

• For both Two and Three wire remote systems, the

provided P-7 wiring connector must be utilized. Please

refer to the wiring instructions.

Two-Wire Remote Systems:

To remotely select either pool or spa operation (3-wire/2-

function) requires 3 wires to be connected to the heater.

A switch mechanism that will provide contact closure

between HIGH/SPA or LOW/POOL and common, needs

to be supplied. This mechanism can be a 3-way switch

or any other remote control system that provides dry

contact closure for either setting. See remote wiring

instructions on this page.

Two or Three-Wire Remote Operation:

To remotely select a single operating ON/OFF mode (2

wire/single function) requires two wires to be connected

to the heater. This requires a switching mechanism that

can be a 2-way switch or a remote control system with a

single dry contact closure. See remote wiring instruc-

tions on this page.

NOTE: Do Not connect wiring to fireman switch

location.

PRESSURE SWITCH

The pressure switch, or heater actuator, insures

that the heater operates only when the filter pump is in

operation. It is located on the inlet/outlet header. It is

factory set at 1.75 PSI for deck level installations.

When the heater is located below the level of the spa or

pool, it may be necessary to reset the pressure switch

to compensate for the no-flow static head. If it is

necessary to reset the pressure switch, utilize the

following procedure:

PRESSURE SWITCH ADJUSTMENT:

1. With pump and heater on, turn adjustment

knob (clockwise) until a click is heard from

the gas valve.

2. Turn adjustment knob (counter clockwise)

1/4 turn.

3. Turn pump off and on several times. Heater

should shut off immediately. If it does not,

repeat steps above until proper adjustments

made.

NOTE: If heater is installed outside of the limits shown,

a flow switch mounted and wired adjacent to the heater

must be used in place of the pressure switch.

TWO SPEED PUMPS

In some cases, the flow on the low speed is

insufficient to operate the heater. This is apparent when

the pressure switch cannot be further adjusted or if the

heater makes banging noises or goes off on high limit.

In these cases, the pump must be run at high speed

when heating the water.

CAUTION: Do not operate the heater without the func-

tion of a properly adjusted pressure switch or flow

switch.

5' Max

FLAME ROLL-OUT SAFETY SWITCH

The heater is equipped with a thermal cutoff device

to prevent flame roll-out in the event the heat exchanger

becomes blocked. This is a "Single-use" type fusible

link or thermal fuse, that must be replaced when dis-

abled by an over temperature condition, caused by

excessive restriction in the heat exchanger flue pas-

sage.

Fig. #9177

HIGH LIMITS

The heater is equipped with two automatic high

limits. Both are located in the inlet/outlet header. Both

are set to open at 135°F.

NOTE: An erratic high limit is often characteristic of

internal heat exchanger problem, i.e. scale buildup,

defective bypass. Refer to troubleshooting sections.

Fig. # 2009

HIGH LIMIT REMOVAL

1. Shut off main electrical power switch to heater.

2. Remove inlet/outlet inspection panel.

3. Remove defective high limit and replace with a new

high limit.

4. Replace inspection panel.

PILOT SAFETY (Millivolt)

The heaters equipped with the standing pilot (milli-

volt system), have pilot generators which act as a safety

device to shut off the flow of gas to the main burners and

the pilot burner in case the pilot flame is extinguished.

The pilot burner must be manually relighted to place the

heater in operation again. Refer to the lighting instruc-

tions provided on the heater label.

PILOT SAFETY (Electronic)

The heater employs a pilot safety which closes the

main gas valve within 8/10ths of a second whenever the

pilot flame is interrupted. Pilot flame is automatically lit

when the device is powered. Unit performs its own

safety check and opens the main valve only after the

pilot is proven to be lit.

BURNER DRAWER REMOVAL

1. Shut off main electrical power switch to heater.

2. Shut off gas upstream of heater.

3. Remove front door.

4. Disconnect gas line from gas valve.

5. Remove (2) screws that mount burner tray to unit,

and (2) screws that secure gas valve to jacket.

6. Disconnect wires that terminate at gas valve.

7. Slide out burner tray.

8. Reverse above procedure to reinstall.

GAS VALVE REMOVAL

1. Shut off gas supply to the heater. Remove gas piping

to gas valve inlet.

2. Disconnect wires, pilot tubing and bleed line, if

required.

3. Turn vertical gas pipe from manifold slightly and

unscrew gas valve.

4. Reverse above procedure to re-install.

MAIN BURNER AND ORIFICE REMOVAL

1. Remove burner drawer. See burner drawer removal

procedure.

2. Remove screws and burner hold down bracket.

NOTE: If the heat exchanger is sooted badly, the

burner hold down bracket and spacer can become

distorted from direct flame impingement and this usually

necessitates replacement of these parts.

3. Lift burners from slotted spacers and slide from

orifices. Clean with a wire brush.

4. Orifices usually do not need to be replaced. To clean,

TUBE CLEANING PROCEDURE

Establish a regular inspection schedule, frequency

depending on local water condition and severity of

service. Do not let the tubes clog up solidly. Clean out

deposits over 1/16" in thickness.

The heater may be cleaned from the return header

side, without breaking pipe connections. It is prefer-

able, however, to remove both headers for better visibil-

ity through the tubes and to be sure the ground-up lime

dust does not get into the system.

Note that you do not remove the top panel or the

heater exchanger, generally.

After reaming, mount the wire brush in place of the

auger and clean out debris remaining in the tubes.

Another method is to remove the heat exchanger,

ream tubes and immerse heat exchanger in non-inhib-

ited de-scale solvent for severe scale build-up.

DESOOTING PROCEDURE

CAUTION: SOOT IS COMBUSTIBLE. EXERCISE

EXTREME CARE:

Soot will clog areas between fins and cause even-

tual tube failure. Any sign of soot at the base of the

burners or around the outer jacket indicates a need for

cleaning.

1. Remove top and flue collector from cabinet.

2. Remove "V" baffles from heat exchanger.

3. Remove burner drawer. (See burner tray removal).

4. Remove heat exchanger from the heater and wash

with a garden hose, making sure soot is removed

from spaces between fins.

5. Reverse above procedure to re-install.

NOTE: In extreme cases it may be necessary to do

steam cleaning at the local car wash. DO NOT

WIREBRUSH.

COMBUSTION CHAMBER REMOVAL

To remove combustion chamber, you must first

have removed the heat exchanger. Unbolt metal com-

bustion chamber retainer from top and remove combus-

tion chamber panels individually.

The Raypak Low Nox Pool Heaters are certified and

tested under the ANSI Z21.56.CSA 4.7 Standards for gas

fired pool heaters.

The heater should be installed to meet all local codes, the

latest editions of the National Fuel Gas Code Z223.1 and

the National Electrical Code, ANSI/NFPA 70.

OPERATION

On call for heat, the ignition system, consisting of an

electronic spark module, gas pilot system is energized.

Providing pilot is proven blower will start running, the

main gas valve will open and the heater will operate.

When the operating control is satisfied the heater will

shut down.

START-UP PROCEDURES (S8610B)

1.Turn on power to the heater with gas supply off.

2.Check ignition module as follows:

a. Set the thermostat or controller to call for heat.

b. Watch for continuous spark at the pilot burner.

c. Check the ignition spark operation. Time must be

within the lockout timing period (15 or 90 seconds).

d. Turn control down to end call for heat and wait 60

seconds on lockout models before beginning step

3.Turn on gas supply.

4.Set controller to call for heat.

5.System should start as follows:

a. Spark will turn on and pilot gas valve will open and

the blower will begin running.

b. Heater will operate until call for heat is satisfied.

FLAME ROLL-OUT SAFETY SWITCH

The heater is equipped with a cutoff device to prevent

flame roll-out in the event the heat exchanger becomes

blocked. This is a "manual reset" type roll-out switch that

must be reset by a service technician after any over

temperature conditions have been fixed. Excessive

restriction in the heat exchanger flue passage may cause

the switch to disable the heater.

BURNER ADJUSTMENT

This burner assembly does not require any primary air

adjustments.

VISUAL INSPECTION

Flame can be observed through the slot opening above

the plenum. Flame color is blue and evenly spread on the

top surface of the burner. At least every three months a

visual inspection should be made of the burners. In case

flame lifting is observed on the burner, check gas pres-

sure on manifold. Gas pressure in manifold should be

3.9" W.C.
