gas piping), and conduit within 5 ft. (1.5 m) of inside walls of swimming pool or spa. IMPORTANT -Reference NEC codes for all wiring standards including, but not limited to, grounding, bonding and other general
wiring procedures.
Body Suction Entrapment- A differential pressure applied to a large portion of the body or limbs can
result in an entrapment.
Evisceration/ Disembowelment - A vacuum applied directly to the intestines through an unprotected
suction outlet sump or suction outlet cover which is damaged, broken, cracked, missing, or unsecured
can result in evisceration (disembowelment).
Mechanical Entrapment- There is potential for jewelry, swimsuit, hair decorations, fi nger, toe or knuckle to be caught in an opening of a suction outlet or suction outlet cover resulting in mechanical entrapment.
WARNING - To reduce the risk of entrapment hazards:
• The maximum system fl ow rate shall not exceed the fl ow rating of any listed (per current revision of
ASME/ANSI A112.19.8) suction outlet cover installed.
• Never use the Pool or Spa if any suction outlet component is damaged, broken, cracked, missing, or not
securely attached.
• Replace damaged, broken, cracked, missing, or not securely attached suction outlet components immediately.
• Install two or more suction outlets per pump in accordance with latest APSP (formally NSPI) Standards
and CPSC guidelines. Follow all applicable National, State, and Local codes.
WARNING – Suction Entrapment Hazard.
Suction in suction outlets and/or suction outlet covers which are damaged, broken,
cracked, missing, or unsecured can cause severe injury and/or death due to the following entrapment hazards:
Hair Entrapment- Hair can become entangled in suction outlets.
Limb Entrapment- A limb inserted into an opening of a suction outlet or suction outlet
cover that is damaged, broken, cracked, missing, or not securely attached can result in a
mechanical bind or swelling of the limb.
• When suction outlets are less than a 18” x 23” equivalent, a minimum of two
functioning suction outlets per pump must be installed. Suction outlets in the same
plane (i.e. fl oor or wall), must be installed a minimum of three feet (3’) [1 meter]
apart, as measured from near point to near point.
• Dual suction outlets shall be placed in such locations and distances to avoid “dual
blockage” by a user.
• Dual suction fi ttings shall not be located on seating areas or on the backrest for
such seating areas.

WARNING – Failure to remove pressure test plugs and/or plugs used in winterization of the pool/spa
from the suction outlets can result in an increase potential for suction entrapment as described above.
WARNING – Failure to keep suction outlet components clear of debris, such as leaves, dirt, hair, paper
and other material can result in an increase potential for suction entrapment as described above.
WARNING – Suction outlet components have a fi nite life, the cover/grate should be inspected frequently and replaced at least every ten years or if found to be damaged, broken, cracked, missing, or
not securely attached.
WARNING – All suction and discharge valves MUST be OPEN when starting the circulation system.
Failure to do so could result in severe personal injury and/or property damage. All drains and suction
outlets MUST have properly installed covers, securely attached using the screws supplied with the
covers. If screws are lost, order replacement parts from your supplier.
WARNING – Hazardous Pressure. Pool and spa water circulation systems operate
under hazardous pressure during start up, normal operation, and after pump shut off.
Stand clear of circulation system equipment during start up. Failure to follow safety
and operation instructions could result in violent separation of the pump housing and
cover due to pressure in the system, which could cause property damage, severe
personal injury, or death. Before servicing pool and spa water circulation system, all
system and pump controls must be in off position and fi lter manual air relief valve
must be in open position. Before starting system pump, all system valves must be set
in a position to allow system water to return back to the pool. Do not change fi lter
control valve position while system pump is running. Before starting system pump,
fully open fi lter manual air relief valve. Do not close fi lter manual air relief valve
until a steady stream of water (not air or air and water) is discharged.
WARNING – Separation Hazard. Failure to follow safety and operation instructions could result in violent separation of pump components. Strainer cover must be
properly secured to pump housing with strainer cover lock ring. Before servicing
pool and spa circulation system, manual air relief valve must be in open position. Do
not operate pool and spa circulation system if a system component is not assembled
properly, damaged, or missing. Do not operate pool and spa circulation system
unless fi lter air relief valve body is in locked position in fi lter upper body.
WARNING – Never operate or test the circulation system at more than 40 PSI.
WARNING – Fire and burn hazard. Motors operate at high temperatures and if they are not properly
isolated from any fl ammable structures or foreign debris they can cause fi res, which may cause severe
personal injury or death. It is also necessary to allow the motor to cool for at least 20 minutes prior to
maintenance to minimize the risk of burns.
WARNING – Failure to install according to defi ned instructions may result in severe personal injury or
death.

WARNING – The following “Safety Rules for Hot Tubs” recommended by the U.S. Consumer
Product Safety Commission should be observed when using the spa.
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. Prolonged immersion in hot water can induce hyperthermia.
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 above 100°F [38°C] can cause fetal damage during the
fi rst three months of pregnancy (resulting in the birth of a brain-damaged or deformed child). Pregnant
women should adhere 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 taking medications, which induce drowsiness, such as tranquilizers, antihistamines or antico-
agulants, should not use spas or hot tubs.
6. If the pool/spa is used for therapy, it should be done with the advice of a physician. Always stir pool/
spa water before entering the pool/spa to mix in any hot surface layer of water that might exceed
healthful temperature limits and cause injury. Do not tamper with controls, because scalding can result
if safety controls are not in proper working order.
7. Persons with a medical history of heart disease, circulatory problems, diabetes or blood pressure prob-
lems should obtain a physicians advice before using spas or hot tubs.
8. Hyperthermia occurs when the internal temperature of the body reaches a level several degrees above
normal body temperature of 98.6°F [37°C]. The symptoms of Hyperthermia include: drowsiness, lethargy, dizziness, fainting, and an increase in the internal temperature of the body.
The effects of Hyperthermia include:
1.
Unawareness of impending danger.
2. Failure to perceive heat.
3. Failure to recognize the need to leave the spa.
4. Physical inability to exit the spa.
5. Fetal damage in pregnant women.
6. Unconsciousness resulting in danger of drowning.

INTRODUCTION:
This manual contains instructions for installation, operation, maintenance, troubleshooting, and parts lists
for the safe use of the swimming pool/spa/hot tub heaters. The manufacturer strongly recommends that the
installer read the manual before installing the swimming pool/spa/hot tub heater. If after reviewing the manual any questions remain unanswered, contact the factory or local representative. Following heater installation,
the installer should leave all manuals with the consumer for future reference.
LIMITED WARRANTY SUMMARY:
The manufacturer warrants the pool/spa/hot tub heater to be free from defects in materials and workmanship, and will within one year from date of installation for all users, for the original purchaser, repair or, at our
option, replace without charge any defective part. The manufacturer further warrants that if the heat exchanger or exchanger headers (water-containing section) leak within one year from date of such installation for all
users, due to defects in materials and workmanship, replacement parts will be provided by the manufacturer.
Cost of freight, installation, fuel, and service labor (after one year) is at user’s expense. For full details of
warranty agreement, see warranty certifi cate included in this manual.
ATTENTION: If the pool/spa/hot tub heater is damaged or destroyed by improper maintenance, exces-
sive water hardness, incorrect water chemistry, or freezing it is not covered under the manufacturer’s
warranty.
MAINTAINING PROPER WATER CHEMISTRY:
WARNING: Failure to maintain proper water chemistry may cause premature
heat exchanger damage or failure.
The heat exchanger in your Trane pool heater is made from the highest quality of copper and nickel (Cupronickel) materials. The premium materials and the exacting processes used in the manufacture of the heat
exchanger is state of the art in pool heater design and manufacture. Yet, it remains vital that the heat exchanger be protected from damaging or corrosive chemicals, insuffi cient water fl ow or improperly balanced water
chemistry. Heat exchanger damage or failure resulting from improper fl ow, improperly balanced pool water
or the improper addition of sanitizers into the water is NOT covered under the terms of your warranty.
The following factors are critical to heat exchanger protection. Follow these guidelines to help prevent
pre-mature damage or failure to your heater and heat exchanger.
1. WATER FLOW THROUGH HEATER
Water must be fl owing through the heater at the minimum rated fl ow rate during operation. Check that
the pump is operating and the system is fi lled with water and purged of all air prior to starting the heater. The
minimum rated fl ow rates are listed on page 25. Some installations may require an adjustment to the water
pressure switch for proper low-fl ow protection. Test your system and if necessary, adjust the water pressureswitch as described on page 35.
2. POOL/SPA WATER CHEMISTRY
The chemistry balance and mineral content of swimming pool water changes daily due to the addition of
pool and sanitizing chemicals, bather loads, rain, runoff and the amount of sun - to name a few. Improper chemistry balance and mineral content can cause scaling and deposits to form on pool walls, in the fi ltration system,
in the heat exchanger tubes and additionally can promote corrosive action to all metals in the water path. Chang-

ing spa water regularly and maintaining the correct chemical balance in your pool/spa will keep the pool/spa
safe and sanitary, and will help protect the heat exchanger. Use a 4-way pool/spa water test kit to check your
water frequently (at least weekly). Use the following guidelines to help protect your heater’s heat exchanger:
3. SKIMMER CHLORINATION
Placing chlorine or bromine tablets directly into the skimmer may result in high chemical concentrations
fl owing through the heater. DO NOT place chlorine or bromine tablets in the skimmer.
4. CHLORINATOR INSTALLATION
Chlorinators must be installed downstream of the heater, and a check valve must be installed between the
heater and chlorinator to prevent high chemical concentrations from back fl owing into the heater. Make sure your
piping arrangement meets the chlorinator installation requirements shown on page 26.
5. BYPASS
Until water chemistry is properly balanced, and if your piping has a bypass valve installed for the heater,
open the bypass so that corrosive and potentially damaging water will not fl ow through the heater and therefore the heat exchanger. Close the bypass valve once the water is properly balanced. Failure to close the
bypass valve when attempting to operate the heater will result in extensive damage to the heat exchanger.
Ensure water fl ow through the heater is restored before operating the heater. A bypass feature is also advantageous for service needs and for the ability to remove the heater from the water path when not heating. Refer
to page 25 for further information.

EQUIPMENT INSPECTION:
On receipt of the heater, inspect the heater carton(s) for damage. If any carton(s) is damaged, note it when
signing for it. Remove the heater from the carton(s) inspect it and advise the carrier of any damages at once.
IMPORTANT NOTICE:
The installation instructions are intended for the use of a qualifi ed technician, specifi cally trained and
experienced in the installation of this type of heating equipment. Some states or provinces require that installation be licensed. If this is the case in the state or province where heater is located, the contractor must be
properly licensed.
WARNING: Failure to comply with the appliance and vent package installation instructions and service
instructions in this manual may result in equipment damage, fi re, asphyxiation, or carbon monoxide
poisoning. Exposure to products of incomplete combustion (carbon monoxide) can cause cancer and
birth defects or other reproductive harm.
CONFORMANCE WITH CODES:
The heater shall be installed in accordance with all local and state codes. The heater installation must conform to the latest edition of the National Fuel Gas Code (ANSI Z223.1/NFPA 54) and with the requirements of
the authority having jurisdiction. Design certifi cation of the heater is in compliance with ANSI Z21.56/CSA 4.7.
For Canadian installations, the heater is to be installed in accordance with the standards CAN/CGA B149.1
and B149.2 – Installation Codes for Gas Burning Appliances and Equipment and/or local codes and, if applicable, CSA C22.1 – Canadian Electrical Code, Part I.
ALTITUDE OF INSTALLATION:
Heaters may be installed at any altitude up to 10,100 ft above sea level, provided the appropriate
modifi cation(s) are performed. The altitudes which require modifi cation vary depending on the model. Parts
necessary to convert the heater for outdoor installation at altitudes up to 7,700 ft (minimum) are included
with the heater. Conversion is accomplished by replacement of the blower air inlet plate, and for indoor applications, installation of a special vent pressure switch. The blower air inlet plates are clearly marked with
the compatible heater model(s), vent confi guration(s), and altitude range(s). Care should be taken to verify
the correct plate (and vent pressure switch, when applicable) is being used to ensure proper heater performance. The vent pressure switch should be provided with the indoor adapter kit, or if you have an older
indoor adapter kit, order p/n FDXLVPS1931 for the high-altitude indoor vent pressure switch.
High-Altitude Conversion Procedure:
1. Identify the altitude of the installation site. This may be done using a GPS device, or by looking up the
altitude for the geographic location. Altitudes for all locations in the United States and Canada may be
found using the zip/postal code database at www.zip-codes.com. If the altitude for the installation site
is greater than 10,100 ft, the heater may not be installed. Note that if installing outdoors, some
Trane heaters may be compatible with your altitude without modifi cation. Table 1 lists the
altitude ranges for heaters without modifi cation. All indoor heaters installed above 2,000 ft require a
special vent pressure switch.
2. Select the appropriate blower air inlet plate to use based on the heater model, vent confi guration
(outdoor or indoor), and altitude needed. Extra plate(s) are included with the heater, packaged in the
plastic bag with this manual. Each plate has a label which identifi es which model(s), vent
confi guration(s), and altitude range(s) it is designed for. Table 1 lists the maximum installation
altitudes using the included conversion plate(s). If installing above 7,700 ft, the high-altitude kit
Page 10
10
FDXLHAK1930 (sold separately) may be necessary.
3. If installing indoors, select the appropriate high-altitude indoor vent pressure switch from the indoor
adapter kit or from the FDXLVPS1931 kit. Each switch has a label which identifi es which model(s) and
altitude range(s) it is designed for.
4. If connected, turn pump, main gas valve, and heater power off.
5. Remove heater front access door.
6. Remove the 4 #10 hex head screws that fasten the blower air inlet plate to the blower, and remove the
blower air plate and discard. Save the 4 screws as they will be needed to install the new plate.
See Figure 26 (page 47).
7. Install the appropriate blower plate from the kit using the 4 screws. It may be helpful to drive the screws
in and out of the plate outside of the heater fi rst to “thread” the holes before installing it in the heater.
8. If the installation is confi gured for indoor venting, a special high-altitude vent pressure switch must be
installed. Follow the instructions for vent kit installation (page 14), but use the appropriate blower air
inlet plate and vent pressure switch for your altitude.
9. Re-install heater front door.
10. If connected, turn pump, main gas valve, and heater power back on.
11. Activate heater and check for proper function.
Table 1 lists the maximum altitudes each model is designed for with: a) no modifi cations, b) the included

INDOOR INSTALLATION AND VENTING:
POSITIVE AND NEGATIVE PRESSURE VENTING SYSTEMS
The heater is designed such that it may be vented using either a negative-pressure or a positive-pressure
venting system. The appropriate system of venting for a particular site will depend on many factors such as
vent termination needs (horizontal/vertical), and the cost of venting system. Table 3 lists the indoor venting
kits available and the limitations of each system. Multipe forced- or induced-draft units should never be vented
uisng common venting or vent terminations.

REVERSIBLE WATER CONNECTIONS:
This heater is designed so that it can be installed with the water connections located on either the right or
left side. Heaters are factory-shipped with right-side water connections. To move the connections to the left
side follow the instructions below. A trained service technician should perform these steps before the heater is
installed.
PROCEDURE:
Before beginning, be aware that it is not necessary to re-
1.
move the water header from the heat exchanger. When
this procedure is complete, the water inlet will be located
at the BACK of the heater. The water outlet will be located at the FRONT.
2. Remove screws and remove both of the upper plastic
heater side panels (see
Figure 7 and Figure 8). Note the
wires that pass through a hole in the heater side panel go
through a split-bushing, which will allow separation of
the wires from the panel without disconnecting them.
3. Disconnect the 2 wires connecting the heater wire har-
ness to the heat exchanger header. One is located on the
water pressure switch and one is located on the temperature limit switch, both on the top of the header. Pull these
wires into the heater cabinet from the hole in the righthand metal side panel in the heater, and re-route them out
through the left-hand metal side panel in the heater.
4. Remove countersunk screws on the heater top and remove louvered exhaust panel on heater top (see Figure
8).
5. Remove the heater top fl ue cover by removing 3 screws on each side of the heater (see Figure 8).
6. Remove screws and remove rain shield assembly (see Figure 8). Note that there are screws which hold the
rain shield assembly to the heat exchanger tube sheets, which also must be removed.
7. Remove the front access panel (see Figure 8).
8. Disconnect water temperature sensor plug from the ignition control board located inside the heater (see
Figure 8).
9. Pull the water temperature sensor wires out of the heater cabinet through the hole in the right-hand metal
side panel.
Lift and rotate the heat exchanger. Do not fl ip. Use care when setting the heat exchanger in place not to
10.
damage the white sealing gaskets or combustion chamber.
11. Route the water temperature sensor wires into the heater cabinet through the hole in the left-hand metal side
panel, and re-connect to the ignition control board.
12. Re-connect the heater wire harness to the water pressure switch and temperature limit.
13. Reverse the above steps to reassemble the heater.

GAS SUPPLY AND PIPING:
To properly size the gas piping for the heater, refer to Tables 10, 11, 12, and 13, depending on natural
or propane gas, and single-stage or 2-stage regulation. Follow local gas codes for proper gas line material
selection (copper, iron, plastic, etc.). It is VERY IMPORTANT when installing a propane heater on a 2-stage
regulation system to follow the gas line sizing data in Table 13 without exception.

GAS SUPPLY INSTALLATION:
The heater is shipped from the factory with the gas connection
located on the left-hand side of the heater cabinet. Insert the pipe to
the gas valve through the grommet in the cabinet side (see Figure
10.) A union should be installed outside the heater cabinet for easy
removal of the gas manifold assembly during service.
A CSA certifi ed main gas shutoff valve must be installed outside
the cabinet and within 6 feet of the heater. This valve must have an
I.D. large enough to supply the proper amount of gas
volume to the heater. See Figure 9.
ATTENTION: Apply joint compound (pipe dope)
sparingly and only to the male threads of pipe joints.
Do not apply joint compound to the fi rst two
threads. Use joint compounds resistant to the action
of liquefi ed petroleum gas. Do not overtighten the
gas inlet pipe or damage may result.
ATTENTION : Do not use fl exible appliance
connectors on any gas connections unless the
connector is CSA approved for outdoor installation,
is marked with BTUH capacity (which must be
equal to or greater than the heater rated input) and
the type of gas (natural or LP).

Figure 9: Gas Piping
Supply
Voltage

Reduction of gas supply pipe or tubing to the inlet of
the heater gas valve must be made at the valve only and must match the valve inlet size (3/4” or 1” NPT).
If more than one appliance is installed on the gas line, consult the local gas company for the proper gas
line size.
Questions on the installation of the proper gas line size can be directed to 908-282-4897.
NATURAL GAS:
The gas meter must have the capacity to supply enough gas to the pool heater and any other gas appliances if they are on the same pipeline (Example: 225 meter = 225,000 BTUH). If doubt exists as to the meter
size, consult the local gas utility for assistance. Natural gas must be “pipeline quality” supplied from a natural
gas utility company. The manufacturer will not be responsible for heaters that soot up due to improper meter
and gas line sizing resulting in improper gas volume, or heaters that are damaged in any way if connected to a
natural gas well.
PROPANE GAS:
All propane gas tanks must be located outdoors and away from pool/spa structure and in accordance with
the standard for storage and handling of propane gas, ANSI/NFPA 58 (latest edition) and applicable local
codes. If the propane gas tank is installed underground, the discharge of the regulator vent must be above the
highest probable water level.
Propane tanks must have suffi cient capacity to provide adequate vaporization for the full capacity of the
equipment at the lowest expected temperatures. Consult a propane company expert for correct sizing.
Page 24
24
ATTENTION: Whenever a high-pressure double regulation system is utilized for propane gas, consult
a propane expert for accurate pipe and pressure sizing. Make sure that 1st and 2nd stage regulators are
large enough to handle the BTUH input listed for the heater(s) being used.
The manufacturer will not be responsible for heaters that soot up due to improper gas line or propane
tank sizing resulting in improper g
as volume.
WATER PIPING:
The heater is designed f
tribution systems. The warranty does not cover heater use with mineral water, seawater (PPM>5000), or other
non-potable waters.
Do not install any restriction in the water pipe
between the heater outlet and the pool/spa with the
exception of:
1. three-way switching valve
2. in-line chlorinator
3. chlorinator check valve
or use with pool and spa/hot tub water only, as furnished by municipal water dis-

Header
Assembly
Gaskets Union Fittings Union Nuts
The heater is equipped with CPVC fl anged pipe nipples to accomodate water piping to and from the pool
or spa. These pipe nipples will accept piping by solvent welding (PVC glue). The fi ttings will accept either a 2”
pipe, or a 2 1/2” pipe fi tting, and seal to the heater header with rubber gaskets. On plastic headers, the fi ttings are
secured in place with plastic union nuts, and on bronze headers (ASME models), the fi ttings are secured in place
with bolts. Assemble these parts to the heater prior to plumbing. Tighten union nuts (or bolts) securely before
gluing fi tt
ings to the ends of the pipe nipples. See Figure 11.
The CPVC fl anged pipe nipples must be installed on the heater inlet and outlet without modifi cation. Pipe,
fi ttings, valves, and any other element of the fi lter system may be made of plastic materials, if acceptable to the
authority having jurisdiction.
Heat sinks, heat tapes, fi remen switches, and check valves are not required on the heater. However, if there
is any chance of “back-siphoning” of hot water when the pump stops running, it is suggested that a check valve
be used on the heater inlet pipe.
The built-in bypass inside the header will maintain proper fl ow through the heat exchanger if the fl ow rate is
within the range for the heater. See Table 14. The minimum fl ow rate is to be calculated or measured with the
infl oor cleaning system in use, if the pool is so equipped, as well as any other jets or other demands on the water
fl ow.
Page 25
If the normal pump and fi lter system fl ow rate exceeds 125 gpm then a manual bypass valve must be installed as shown in Figure 12. Damage caused by fl ow rates outside this range will void the manufacturer’s
warranty.
25
The installation is as follows:
Install a fl ow meter on the outlet line of the heater.
1.
2. Adjust the manual bypass valve until the fl ow
rate is within the fl ow rate range specifi ed for the
heater.

ATTENTION: Improperly adjusted manual bypass valves will result in damage to the heater if the
fl ow rates are not maintained as specifi ed in Table 14 under all operating conditions. The heat exchanger will fail and this damage will not be covered under warranty.

INSTALLATION ABOVE POOL/SPA SURFACE:
If the heater is installed less than three (3) feet above the surface of the pool/spa water, install eyeball fi ttings or directional fl ow
fi ttings on the end of the return water line to the pool/spa to create
adequate back pressure at the heater to operate the pressure safety
switch when the fi lter pump is running.
If the heater is installed more than three (3) feet above the surface
of the pool/spa water, install a loop as shown in Figure 15 to prevent
drainage of water in the heater during a fi lter change.
For installation below the pool/spa surface, refer to Section III.
Figure 15: Heater installation

AUTOMATIC CHLORINATORS AND
CHEMICAL FEEDERS:
If used, a chlorinator must be installed downstream from the
heater in the pool return line and at a lower elevation than the heater
as shown in Figure 16. Install a separate positive seal corrosion
resistant check valve between the heater outlet and the chlorinator
to prevent highly concentrated sanitizers from back-siphoning into
the heater. Back-siphoning usually occurs when the pump is shut off
and a pressure differential is created.
Figure 16: Automatic chlorinator
Page 27
PRESSURE RELIEF VALVE:
Some local building codes require a pressure relief valve for pool/spa heaters. The header has a 3/4” port which can be used for this purpose (see Figure
24 for location of port). A 3/4” pressure relief valve having a discharge capacity greater than or equal to the Btu/hr input of the heater, and a pressure rating
equal to or less than the working pressure is recommended. See the rating plate
located inside the front access panel on the heater for the input rating and working pressure. Remove the factory-installed pipe plug, and install the pressure
relief valve using a suitable amount of pipe thread sealant or tefl on tape on the
threads. Install the pressure relief valve with the discharge connection facing
the ground. If necessary, connect a pipe (of the same size as the valve outlet) to
the outlet and run it to a safe place of discharge. Do not install any shut-off or
restriction in this drain line.
ELECTRICAL SPECIFICATIONS:
WARNING: It is required that licensed electricians do all electrical wiring. Risk

GAS LINE TESTING:
The appliance and its gas connection must be leak tested before placing the appliance in operation. The
heater and its individual shutoff valve must be disconnected from the gas supply during any pressure testing
of that system at test pressure in excess of ½ psig (3.45 kPa). The heater must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply
piping system at test pressure equal to or less than ½ psig (3.45 kPa).
Gas supply line must be capped when not connected. After pressure testing, reconnect the gas piping to the
gas valve. Turn gas supply “ON” and test all pipe and tubing joints for leaks. Use a soap and water solution.
WARNING: EXPLOSIVE HAZARD. The use of an open fl ame to check for gas
leaks could cause an explosion resulting in severe injury and/ or death. Shut off gas
and fi x even the smallest leak right away. Be sure to leak test the heater gas manifold
fi ttings using the above procedure once the heater is in operation.
Page 33
GAS PRESSURE TESTING:
The following gas pressure requirements are important to the proper operation of the burners in gas heat-
ers. Improper gas pressure or gas volume will create the following conditions:
1. Flame burns totally yellow.
2. Flame lifts off burner.
3. Heat exchanger soots up. The gas pressure regulator on all heaters is preset at the factory,
but the setting should be verifi ed by the installer to ensure proper operation.
If gas pressure is inadequate, check for undersize piping between the gas meter and the heater or for a
low-capacity gas meter.
GAS PRESSURE TEST PROCEDURE:
Refer to Figure 22 for the location of components used in this procedure on heaters being serviced.
1. Obtain the necessary equipment:
a. Manometer to read pressure in inches of water column
b. 1/8” pipe nipple (1/8” thread x 1” long)
c. 3/16” hex wrench
d. Flat screwdriver
2. Remove the 1/8” plug from the gas valve.
3. Install the 1/8” pipe nipple into the gas valve.
4. Attach the manometer to the pipe nipple.
5. Turn on the water system and start the heater following the lighting & operating instructions on the
label affi xed inside the front access panel. If there is more than one pool/spa heater connected to
the gas supply line, turn each of those appliances “ON” while testing the heater.

WATER PRESSURE SWITCH TEST / ADJUSTMENT PROCEDURE:
The pressure switch is preset at the factory for most typical, deck level installations. When the heater is located
above or below the level of the pool or spa, the pressure switch may require adjustment to compensate for the change
in static head pressure. The following procedure is recommended when the switch needs adjustment and/or is replaced:
For Installations with Heater Above Water Level:
1. Be sure the fi lter is clean before making the adjustment.
2. Turn “ON” the fi lter pump and ensure all air is out of the water lines, and ensure water fl ow rate is at
least the rated minimum (see Table 14).
3. Turn “ON” the heater and adjust the thermostat to create a call for heat.
4. If the heater does not light, adjust the pressure switch by turning the adjustment knob on the pressure
switch counter-clockwise, until the heater lights. Turning the adjustment knob counterclockwise
decreases the pressure needed to close the switch.
5. Check the function of the pressure switch by turning the fi lter pump on and off several times. The pool
heater should turn off immediately when the pump is turned off. Never allow the heater to operate with
less than the minimum rated water fl ow rate.
For Installations with Heater Below Water Level:
1. Be sure the fi lter is clean before making the adjustment.
2. Turn “ON” the fi lter pump and ensure all air is out of the water lines, and ensure water fl ow rate is at
least the rated minimum (see Table 14).
3. Turn “ON” the heater and adjust the thermostat to create a call for heat.
4. Turn the adjustment knob on the pressure switch clockwise, until the heater turns off, then turn the knob
¼ turn counter-clockwise, so that the heater turns back on. Turning the adjustment knob clockwise
increases the pressure needed to close the switch.
5. Check the function of the pressure switch by turning the fi lter pump on and off several times. The pool
heater should turn off immediately when the pump is turned off. Never allow the heater to operate with
less than the minimum rated water fl ow rate.
TWO-SPEED PUMP:
In a few cases the pressure from a two-speed pump is below the 1- pound minimum required to operate the water pressure switch on the heater. This is apparent when the pressure switch cannot be further adjusted. In these cases
the pump must be run at high speed to operate the heater. If the pump and piping arrangement are such that the required 1-pound minimum pressure cannot be obtained, do not attempt to operate the heater. Correct the installation.
Page 36

TEMPERATURE ADJUSTMENT:
This pool heater is equipped with a digital thermostat which allows the user to select the desired water
temperature. The heater will then function automatically to maintain the desired temperature. The heater has
3 modes of operation:
1. STANDBY: in this mode, the heater will not function to heat the water.
2. SPA: in this mode, the heater will automatically function to maintain the water temperature setting
for SPA mode.
3.
POOL: in this mode, the heater will automatically function to maintain the water temperature setting for POOL mode.
Use the MODE button to change modes. The indicator lights will illuminate to show which mode the
heater is currently in. Each mode has its own temperature setting, allowing the user to have 2 individual
pre-set temperature settings. To adjust the temperature while in SPA or POOL mode, use the UP and DOWN
buttons. The numeric display will fl ash to indicate the temperature setting is being displayed / adjusted. When
the numeric display is not fl ashing, the actual water temperature is being displayed. The temperature settings
for both SPA and POOL modes are initially set at the factory to 65°F. The minimum allowed settings for SPA
and POOL modes are both 65°F. The maximum allowed settings for SPA and POOL modes are adjustable up
to 104°F using the temperature lockout feature (see below).
After selecting SPA or POOL mode or adjusting the temperature setting, it is normal for the heater to
delay up to 10 seconds before the heater starts operating. This delay is an internal self-test of the heater. On
occasion, the numeric display may show a diagnostic error code; refer to list of diagnostic error codes in Figure 27. Pressing the MODE button to cycle to STANDBY and back to SPA or POOL will clear a diagnostic
error code. When clearing a diagnostic error code this way, it is normal for the heater to delay up to 5 seconds
before resuming normal operation, assuming the diagnostic error code does not re-appear.

TEMPERATURE LOCK-OUT:
The digital thermostat in this pool heater allows the user to lock the maximum temperature setting allowed.
This feature is useful for preventing unauthorized users from manually adjusting the temperature settings higher
than desired. On a new heater, the maximum allowed temperature lock settings are initially set at the factory to
90°F for POOL mode, and 104°F for SPA mode. To adjust these settings, use the following procedure:
1. Use the MODE button to put the heater in STANDBY mode.
2. Press and hold both the UP and DOWN buttons at the same time.
3. After 3 seconds, the thermostat enters maximum temperature lock adjustment mode.
4. The SPA indicator light illuminates and the numeric display shows the current SPA mode maximum
temperature lock setting. Both the SPA indicator light and the numeric display fl ashes rapidly when in
adjustment mode.
5. Use the UP and DOWN buttons to set the desired maximum temperature lock setting. When fi nished,
press the MODE button.
6. The POOL indicator light illuminates and the numeric display shows the current POOL mode
maximum temperature lock setting. Both the POOL indicator light and the numeric display fl ashes
rapidly when in adjustment mode.
7. Use the UP and DOWN buttons to set the desired maximum temperature lock. When fi nished, press
the MODE button.

to place the heater in “STANDBY”. Then press and hold the “UP” and “MODE” buttons until the display shows
the °F/°C selection. Press the “DOWN” button to toggle between selections. To accept the selection, press the
“MODE” button. If the user does not act, the selection will be automatically accepted after 60 seconds.
HEATING MODE:
The control continually compares the water temperature with the set point and the high limit temperature.
When the water temperature is more than 1° below the set point a call for heat is generated and a heating
cycle is initiated.
1. The control checks for open contacts at the blower vacuum switch.
2. The control energizes the blower and the igniter. The igniter heat-up time is approximately 20 seconds.
The blower is running a pre-purge cycle during this time.
3. The control checks for closed contacts at the blower vacuum switch.
4. When the igniter reaches the proper temperature a 4-second trial for ignition begins. The control opens
the gas valve and monitors fl ame current. The igniter is turned off when fl ame is sensed or after 4 seconds.
5. The blower vacuum switch, the temperature limit switches, the vent pressure switch, the water pressure
switch, the water temperature sensors, and the fl ame sensor are constantly monitored during a call for
heat to assure the heater is operating properly.
6. When the thermostat is satisfi ed and the call for heat ends the control immediately de-energizes the
gas valve. Flame is extinguished.
7. The control operates the blower during a 30-second post-purge period.
Page 38
38
FAILURE TO LIGHT – RETRY:
If the fi rst ignition attempt fails during a normal heating cycle the control will make two (2) additional
ignition attempts:
1. The control de-energizes the gas valve after the 4 second ignition trial ends.
2. The control operates the blower during a 30 second post-purge period.
3. The control monitors for open contacts at the blower vacuum switch.
4. The control performs a gas valve relay check.
5. A normal ignition sequence resumes with Item #2 in “Heating Mode” (above). If the third ignition
trial fails the control enters a safety lockout (or “hard” lockout) after the post-purge period of the
third failed trial.
6. The error code “IF” is displayed and the “SERVICE” indicator is illuminated.
a. The control automatically resets and clears the “IF” error code without any user intervention after
60 minutes. If there is a call for heat after reset the control will make three (3) trials for ignition. If
ignition is not established the control will again enter safety lockout for 60 minutes. This cycle will
continue until ignition is established or the call for heat is removed.
b. The user can reset the control and clear the “IF” error code by pressing the “MODE” button to
move through “STANDBY” and return to the previous mode (“SPA” or “POOL”).
LOSS OF FLAME – RECYCLE:
If fl ame is established and then lost, the control will make ten (10) attempts at ignition. If fl ame is lost
within ten (10) seconds of ignition the control will respond within 2 seconds. If fl ame is lost more than ten (10)
seconds after ignition the control will respond within 0.8 seconds.
1. The control de-energizes the gas valve and the blower.
2. The control monitors for open contacts at the blower vacuum switch.
3. The control performs a gas valve relay check.
4. A normal ignition sequence resumes with Item #2 in “Heating Mode” (above).
5. If the tenth ignition trial fails the control enters a safety lockout (or “hard” lockout) after the postpurge period of the tenth failed trial.
6. The error code “IF” is displayed and the “SERVICE” indicator is illuminated.
a. The control automatically resets after 60 minutes. If there is a call for heat after reset the control
will make three (3) trials for ignition. If ignition is not established the control will again enter safety
lockout for 60 minutes. If fl ame is established but is lost the control will make ten (10) attempts at
ignition. This cycle will continue until ignition is established or the call for heat is removed.
b. The user can reset the control and clear the “IF” error code by pressing the “MODE” button to move
through “STANDBY” and return to the previous mode (“SPA” or “POOL”).
KEYPAD INPUTS:
The control accepts user inputs via the keypad on the front panel.
1. When changing the mode from “STANDBY” to either “SPA” or “POOL” there may be up to a 10second delay for the blower fan to begin running. The control performs an internal self-test and then
verifi es that the blower vacuum switch contacts are open before energizing the blower.
2. It is normal for the heater to display a 1 to 2 second delay in responding to any keypad input.
3. It is normal for the heater to display up to a 5 second delay when the keypad is used to reset the control
to clear an error code.
4. The control will accept a mode change during lockout after 5 seconds. The control will continue to
display the error code and remain in lockout until it is reset. At reset the control will go to the last saved
mode.
Page 39
AUTOMATIC RESET TIME:
The heater will automatically reset when an error condition is corrected and resume operation as detailed
in the table below. The heater can be manually reset using the keypad by cycling the mode button through
“STANDBY” and back to the original operating mode (“SPA” or “POOL”).
PERIODIC INSPECTION:
The heater is designed and built for long performance life when installed and operated according to the
manufacturer’s directions. Regular inspection by qualifi ed service personnel is recommended to keep the
heater working properly. The following inspection points are suggested to help maximize heater life.
1. Periodically check the venting on outdoor heaters. The heater’s venting areas (the louvered top
panel) must never be obstructed in any way and minimum clearances must be observed to prevent
restriction of combustion and ventilation air. Remember that shrubs grow and in time may obstruct
a heater’s venting areas.
2. Check the venting of indoor heaters for looseness and possible leaks. Keep all openings for combustion and ventilation air clear and unobstructed.
3. Keep the entire pool heater area clean and free of all debris, combustible materials, gasoline, and
other fl ammable vapors and liquids. Remove any leaves or paper from around the heater.
4. Do not store chlorine, other pool chemicals, or other corrosives in the vicinity of the heater.
5. If the heater is operating on propane gas, the tank must not fall below 30% full or damage to the
heater may occur. The manufacturer will not be responsible for heaters that soot up due to improper gas level in the tank resulting in inadequate gas volume.
6. If another appliance is added to the gas line at a later date, consult the local gas company to be sure
the gas line will have the capacity to supply both units at full input rating at the same time.
7. Do not use the heater if any part has been under water. Contact a qualifi ed service technician to
inspect the entire heater and replace any part of the control system or gas valve that was under
water. If heater has been totally submerged in water it must be removed and the entire heater must
be replaced.
8. An inspection program is a good preventative maintenance measure. Keep this manual in a safe
place for future reference for yourself as well as for a service technician to consult when inspecting or servicing the heater. Additional inspection procedures to be performed by a qualifi ed service
technician are covered in
Section VI of this manual.
39
WINTERIZATION:
In moderate climates, the heater can continue to operate during short-term cold spells. Do not use the
heater to maintain the water temperature just above freezing or for freeze protection. Care must be taken to
avoid freeze-up in the heater. When it is used during freezing weather, the pump must run continuously. The
heater is not warranted against freeze-ups. In regions where freezing temperatures are encountered, all water
must be drained from the heater when it is out of service, to prevent damage to the heater and piping. Draining the heat exchanger is recommended as part of the season’s shutdown procedures.
ATTENTION: A heater damaged by freezing is not covered under the manufacturer’s warranty.
Page 40
40
DRAINING THE HEAT EXCHANGER:
This procedure applies to installations where the heater is located higher than the pool water level. If it
is necessary to drain a pool heater located below the pool water level, you must either partially drain the
pool, or isolate the pool heater from the pool using valves.
1. Set the heater to STANDBY mode using the keypad.
2. Turn the electricity to the heater OFF at the circuit breaker panel.
3. Turn the heater gas valve OFF using t
he knob or switch on the valve (see Figure 22).
4. Turn the heater’s gas supply OFF at the main shut-off valve outside the heater cabinet.
5. Be sure the circulating pump is OFF.
6. Remove the plastic drain plug (see Figure 24).
7. Allow all water to drain from the heater.
8. Re-install the plastic drain plug.
SPRING START-UP:
1. Inspect and clean the heater, being sure the heater is free of leaves and debris prior to startup.
2. Be sure inlet and outlet piping are properly attached to the heater and the drain valve is closed.
3. Turn the fi ltration system pump “ON” and allow the system to run long enough to purge all the air
from the lines.
4. Turn the gas supply to the heater “ON”.
5. Set the temperature control using the keypad to “POOL” or “SPA” and adjust the set point to the
desired temperature setting.
6. If operating diffi culties are encountered, contact a qualifi ed service company for assistance.
ATTENTION: Heater installation, checkout, and start-up should now be completed. BE SURE to
leave the Owner’s Manual with the pool owner.

SECTION IV. QUALIFIED TECHNICIAN – MAINTENANCE & SERVICING
GENERAL:
ATTENTION: Only qualifi ed service technicians, with appropriate test equipment, should be allowed to
service the heater. Bear in mind that all of the components that comprise the system have an effect on heater
operation. Before proceeding with heater related troubleshooting tips covered in Section VII, be certain that
the pump is operating correctly, the fi lters and strainers are not blocked, the valves in the piping are properly
positioned, and the time clocks are properly set.
WARNING: EXPLOSION HAZARD Do not attempt to repair any components of
this heater. Do not modify the heater in any manner. To do so may result in a malfunction that could result in death, personal injury, or property damage. Check with
the consumer to see if any part of the heater has been under water. Replace any part
of the control system and any gas control that has been under water.
MAINTENANCE:
The following inspection procedures are recommended to be performed as part of annual heater mainte-
nance and to ensure safe operation.
1. External heat exchanger
2. Internal heat exchanger
3. Main burner fl ame patterns
4. Main burner orifi ces
5. Operating controls
EXTERNAL HEAT EXCHANGER INSPECTION AND CLEANING:
Remove the louvered exhaust cover panel (see Figure 8) and inspect the external surfaces of the heat exchanger
for soot accumulation. If soot has accumulated, it must be removed by following the recommended procedure:
1. Turn pump, main gas valve, and heater power “OFF”.
2. If the heat exchanger must be removed, follow the procedure in Section II, under “Reversible Water Connections”.
WARNING: BURN HAZARD Do not use a wire brush to remove soot from the
heat exchanger. This could cause a spark and ignite the gases trapped within the soot.
3. Using a soft-tipped brush such as a paint brush, apply a degreaser to the entire heat exchanger surface (top and bottom). Allow the heat exchanger to sit for a period of time to allow the degreaser
to loosen the soot. Wash the heat exchanger using a garden hose ensuring both the top and bottom
surfaces are cleaned. Re-assemble the heater by reversing the disassembly steps.
Although the heat exchanger should be cleaned of soot and reinstalled, the fact that sooting occurred
should be investigated, as it may indicate other problems such as:
Insuffi cient air supply
•
• Inadequate venting
• High or low gas pressure
Page 42
42
• Blockage of burner tubes or orifi ces
• Blockage of blower inlet
• Low voltage supply causing blower to “spin” slower
• Improper heater location installation
• Incorrect gas supply pipe size
• Excessive water fl ow through heat exchanger
• LP tank below 30% full
COMBUSTION CHAMBER:
The combustion chamber is a single-piece casting. If damaged, the entire chamber must be replaced.
BURNER INSPECTION AND CLEANING:
With the heater “ON”, remove the front access panel and make a visual inspection of the main burners
through the sight glass (see Figure 21.) The main burner fl ames should be about ½” to 2” in height and should
not “lift” off the burner ports (see Figure 25).
A normal fl ame is blue, without yellow tips. Yellow tips or a totally yellow or “lazy” fl ame may be an indication of a fuel-rich mixture due to restricted air supply. Spider nests in the burner and/or gas orifi ces may also
cause yellow tips.

7. Replace the display board or bezel & keypad assembly, and reverse the above steps to reassemble.
BLOWER VACUUM SWITCH:
The blower vacuum switch is a safety device that prevents the ignition sequence from continuing unless
the blower is developing suffi cient airfl ow for combustion. Figure 21 shows the location of the blower vacuum switch in the heater cabinet. When the blower achieves suffi cient airfl ow, the negative pressure created in
the blower housing closes the contacts on the blower vacuum switch, indicating to the ignition control board
that it is safe to continue the ignition sequence. A silicone tube connects the blower vacuum switch with the
blower as shown in Figure 21.
To remove the blower vacuum switch:
1. Turn pump, gas supply, and heater power “OFF”.
2. Remove the front access panel. It is secured with (4) screws.
3. Remove the wires from the pressure switch.
4. Pull the tubing from the hose barb on the switch.
5. Remove the (2) screws that secure the pressure switch to the control panel.
6. Reverse the above procedure to install the blower vacuum switch.
HIGH LIMIT SWITCHES:
The high limit is an automatically resetting safety device wired in series with the thermostat and gas
valve. See Figure 24. The heater is equipped with two automatic high limits, located on the water header.
If the water temperature exceeds the limit set point, the gas valve will be closed, shutting off gas supply to
the burners.
Erratic high limit operation is often an indication of a problem with water fl ow. Reduced fl ow may be caused by:
1. Clogged fi lter or strainer.
2. Excessive fl ow through the external bypass if one is used.
3. Lime scale accumulation in the heat exchanger.
To replace a high limit switch:
1. Turn pump, gas supply, and heater power “OFF”.
2. Drain the heat exchanger of all water.
3. Unplug the high limit wires from the wiring harness.
Page 46
46
4. Unscrew the high limit switch from the header.
5. Replace the high limit switch. Use new sealant on the high limit switch threads before reinstalling.
6. Reverse the above procedure to install the high limit switch.
EXHAUST GAS TEMPERATURE LIMIT:
The exhaust gas temperature limit monitors the fl ue gas temperature above the heat exchanger and trips if
temperature rises high enough to indicate that the heat exchanger has been damaged and is no longer transferring heat to the pool water effectively. If this limit trips, effort must be made to rectify the situation has
damaged the heat exchanger. This is generally due to low water fl ow, poor water chemistry, or a combination
of these and other factors. Replace the limit as well as the heat exchanger before operating the unit again.
Running the unit without replacing the heat exchanger after this limit trips could damage the entire unit and
will not be covered by the manufacturer’s warranty. To replace the exhaust gas temperature limit:
1. Turn pump, gas supply, and heater power “OFF”.
2. Remove the upper end cap on the header side of the unit (see Figure 8).
3. Unplug the two wires from the exhaust gas temperature limit located in the fl ue collector panel above
the middle of the header.
4. Unscrew the (2) screws securing the limit to the panel and remove the limit and gasket.
5. Place the new limit and gasket in place and reverse the above steps to complete the procedure.
THERMISTOR:
The thermistor monitors the return water temperature. See Figure 24. To replace the thermistor:
1. Turn pump, gas supply, and heater power “OFF”.
2. Drain the heat exchanger of all water.
3. Remove the front access panel. It is secured with (4) screws.
4. Unplug the thermistor connector from the ignition control board.
5. From outside the heater, pull the thermistor leads out of the control box and through the hole in the
heater chassis.
6. Unscrew the thermistor from the inlet side of the header.
7. Replace the thermistor. Use new sealant on the thermistor threads before re-installing.
8. Reverse steps above to complete the procedure.
WATER PRESSURE SWITCH:
The water pressure switch (Figure 24) is preset at the factory for most typical, deck level installations.
When the heater is located above or below the level of the pool or spa, the pressure switch may require
adjustment to compensate for the change in static head pressure. If adjustment is needed, the procedure is
detailed in Section III, under Water Pressure Switch Test / Adjustment Procedure.
ATTENTION: Do not operate the pool heater without the function of a properly adjusted pressure
switch or fl ow switch.
To replace the pressure switch:
1. Turn pump, gas supply, and heater power “OFF”.
2. Unplug the high limit terminals from the main wire harness.
3. Remove the (4) screws securing metal trim panel around the header.
Page 47

4. Remove the wires from the pressure switch.
5. Using two ½” open-end wrenches disconnect the pressure switch from the pressure switch tubing.
6. Replace the pressure switch. Use new sealant on the pressure switch threads before re-installing.
7. Reverse steps above to complete the procedure.
TRANSFORMER:
The transformer converts the fi eld supply voltage (either 240 VAC or 120 VAC) to a 120 VAC output for
blower and igniter power, and a 24 VAC output for powering the ignition control board, control circuits, and
gas valve. See Figure 21 for its location.
To replace the transformer:
1. Turn pump, gas supply, and heater power “OFF”.
2. Remove the front access panel. It is secured with (4) screws.
3. Disconnect all wires from the transformer leads.
4. Remove the (2) screws that secure the transformer to the control box.
5. Replace the transformer. Reassembly is the reversal of steps above.
BLOWER:
The blower provides the air that mixes with the gas at the
main burners for the combustion process. The blower operates during the pre-purge time (approximately 30 seconds) at
the beginning of each ignition cycle, during the entire time the
gas valve is open and the burners are fi ring, and for 30 seconds after the valve gas closes. See Figure 21 and Figure 26.

SECTION V. TROUBLESHOOTING
GENERAL:
ATTENTION: These instructions are intended for the use of qualifi ed personnel trained and experi-
enced in the installation and servicing of this type of heating equipment and its related system components. Some states may require installation and service personnel to be licensed. Persons not qualifi ed
should not attempt to repair this equipment according to these instructions. These instructions and
procedures are not for the use of “do-it-yourself” consumers.
WARNING: BURN HAZARD The operation of the heater with the pump shut off
could cause heater overheating and fi re. Never operate heater with the pump shut off.
ATTENTION: As a preliminary check, make sure that all wire connections are clean
and tight and that all wiring conforms to the wiring diagram.
AUTOMATIC RESET TIME:
The heater will automatically reset when an error condition is corrected and resume operation. The heater
can be manually reset using the keypad by cycling the MODE button through “STANDBY” and back to the
original operating mode (“POOL” or “SPA”).
ERROR CODES:
49
See Figure 27 on page 51 for an error code chart.
TROUBLESHOOTING:
See Figure 28 on page 53 for troubleshooting guide.
SUPPLY WIRING:
If the heater is connected to the line side of the circuit it will be powered at all times. In this situation,
when the pump shuts down the heater will display a fault code of “LO”. If there is a call for heat and the
pump then restarts there will be a 2 minute delay for the heater to fi re. After the pump has been running for at
least 2 minutes there is no delay for heater operation.
Wiring the heater to the load side of the timer or controller will not result in a 2 minute delay if the pump
primes quickly enough to activate the heater’s water pressure switch. If the pump is slow to prime the heater
may display an “LO” fault code and will take 2 minutes to automatically restart. If the pump has primed, this
wait can be avoided by manually clearing the error code via the keypad by changing the mode through the
“STANDBY” setting and returning to the initial setting (“SPA” or “POOL”).
When a heater is wired to the line side of the power circuit (continuous power) the blower will not operate
when the pump is cycled via a time clock or other switch method.
INTERNAL WIRING:
If the heater display is blank after the electrical has been installed, refer to Figure 27 and Figure 28 to determine the cause. The ribbon cable between the display board and the ignition control board is polarized and
cannot be inserted upside down if it was removed when electrical was done.
Page 50

FUSE SPECIFICATIONS:
The fuse designations are printed on the ignition board and the control board. See Figure 21 for board
locations. Fuses are available as common hardware items or may be purchased from the manufacturer in a
service parts kit. The fuse specifi cations are:
• F1 fuse (low voltage): 3A blade style fast-acting automotive fuse, type 257
