SAFETY INSTRUCTIONS (Continued)

This appliance is equipped with an unconventional gas control valve that is factory set with a manifold pressure of -.2 inches wc. Improper installation, adjustment, alteration, service or maintenance can cause property damage, personal injury or loss of life.

Installation or service must be performed by a qualified installer, service agency or the gas supplier. If this control is replaced, it must be replaced with an identical control.

Do not attempt to adjust the gas flow by adjusting the regulator setting.

Risk of fire or explosion from incorrect fuel use or faulty fuel conversion. Do not try to run a heater set

up for natural gas on propane gas or vice versa. Only qualified service technicians should attempt to convert heater from one fuel to the other.

Do not attempt to alter the rated input or type of gas by changing the orifice. If it is necessary to convert to a different type of gas, consult your Sta-Rite dealer. Serious malfunction of the burner can occur which may result in loss of life. Any additions, changes, or conversions required in order for the appliance to satisfactorily meet the application needs must be made by a Sta-Rite dealer or other qualified agency using factory specified and approved parts.

The heater is available for use with natural gas. It can be converted to propane gas. Refer to the nameplate for the type of gas the heater is equipped to use.

• Use this heater only with natural gas. Do not attempt to

convert it to another type of gas.

• If propane gas is the only available fuel, have a qualified

service technician convert the heater to propane before putting heater into operation.

Risk of fire or explosion from flammable vapors. Do not store gasoline, cleaning fluids, varnishes,

paints, or other volatile flammable liquids near heater or in the same room with heater.

Risk of fire, carbon monoxide poisoning, or asphyxiation if exhaust venting system leaks. Only quali-

fied service technicians should attempt to service the heater, as leakage of exhaust products or flammable gas may result from incorrect servicing.

Risk of explosion if unit is installed near propane gas storage. Propane (LP) gas is heavier than air.

Consult local codes and fire protection authorities about specific installation requirements and restrictions. Locate the heater away from propane gas storage and filling equipment as specified by the Standard for the Storage and Handling of Liquified Petroleum Gases, CAN/CSA B149.2 (latest edition) or ANSI/NFPA 58 (latest edition).

Risk of asphyxiation if exhaust is not correctly vented. Follow venting instructions exactly when installing heater. Do not use a draft hood with this heater,

as the exhaust is under pressure from the burner blower and a draft hood will allow exhaust fumes to blow into the room housing the heater.

The heater is supplied with an integral venting system for outdoor installation. A vent conversion kit (See Page 14 for Part Numbers for Conversion Kits) is available for installations in enclosures (Canada) or indoors (U.S.). Use the specified venting, and only the specified venting, when heater is installed in an enclosure or indoors. In Canada, this pool heater can only be installed outdoors or in an enclosure that is not normally occupied and does not directly communicate with occupied areas. See Page 11 for enclosure venting requirements.

Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Wiring errors can also destroy the control board.

Connect heater to 120 or 240 Volt, 60 Hz., 1 Phase power only.

Verify proper operation after servicing. Do not allow children to play on or around heater or asso-

ciated equipment. Never allow children to use the pool or spa without adult

supervision. Read and follow other safety information contained in this

manual prior to operating this pool heater.

GENERAL SPECIFICATIONS/ REQUIREMENTS

NOTICE: Combustion air contaminated by corrosive chemi-

cal fumes can damage the heater and will void the warranty. NOTICE: The Combination Gas Control Valve on this

appliance differs from most appliance gas controls. If it must be replaced, for safety reasons replace it only with an identical gas control.

NOTICE: The jacket covers must be in place to provide proper ventilation. Do not operate the heater for more than five (5) minutes with the jacket covers removed.

This heater is design certified by CSA International as complying with the Standard for Gas Fired Pool Heaters, ANSI Z21.56* CSA 4.7, and is intended for use in heating fresh water swimming pools or spas.

NOTICE: Do not use this heater as a heating boiler, water heater, or for heating salt-water pools. This heater is intended for use in heating fresh water swimming pools or spas only.

The heater requires an external 120 or 240 VAC singlephase electric power source.

The heater is design certified by CSA International for installation on combustible flooring. Specified minimum clearances must be maintained to combustible surfaces (see “Installation Instructions”, Pages 9 and 10).

The heater should be located in an area where leakage of the heater or connections will not result in damage to the area adjacent to the heater or to the structure. When such locations cannot be avoided, it is recommended that a suitable drain pan, adequately drained, be installed under the heater. The pan must not restrict air flow.

The heater may not be installed within five feet of the inside surface of a pool or spa unless it is separated by a solid fence, wall or other permanent barrier.

Propane (LPG) fired heaters must not be installed in Massachusetts, by order of the Massachusetts State Fire Marshall. For more information, call the Fire Marshall’s office.

DESCRIPTION OF THE HEATER

Figure 2 is a diagram of the heater showing how it operates. Precisely matched orifice plates meter the air and gas into

the mixer. The blower draws the air and gas through the mixer and forces it into the burner’s flameholder. A sealed heat exchanger surrounds the flameholder, discharging exhaust gases out the flue.

Two inch PVC water piping connects directly to the manifold/header on the heat exchanger using 2” PVC slip unions provided with the heater. The outer manifold remains cool; no heat sinks are required. A thermal regulator and an internal bypass regulate the water flow through the heat exchanger to maintain the correct outlet temperature.

A plastic jacket with the top half split for access surrounds the assembly. The heater control board assembly, set into the top of the jacket, contains the operating controls.

SEQUENCE OF OPERATION

An electronic temperature sensing thermistor in the manifold adapter inlet controls the heater operation. When the inlet water temperature drops below the temperature set on the operating control, the burner controller supplies power to the combustion air blower through a series of safety interlocks. The interlocks consist of

• the pressure switch (PS), which senses that the pump is

running,

• the high limit switch (HLS), which opens if the heat

exchanger outlet temperature goes above 135°F (57°C), and

• the automatic gas shutoff (AGS) switch, which opens

if the heat exchanger outlet temperature goes above 140°F (60°C).

• the stack flue sensor (SFS), which shuts down the heater

if the flue gas temperature reaches 500°F (260°C).

The air flow switch (AFS) senses the pressure drop across the air metering orifice. As soon as there is sufficient air flow, the AFS closes, closing the circuit to the hot surface igniter (HSI), which ignites the fuel mixture.

On a call for heat, the blower and HSI are energized. In about 20 seconds, the gas valve opens and ignition occurs. The HSI then switches to a sensing mode and monitors the flame.

The heater is equipped with a digital operating control that enables the user to pre-set the desired pool and spa water temperatures. The control enables the user to select between pool and spa heating, and features a digital display that indicates the water temperature.

F. Before operating the appliance for the first time or after

it has been off for an extended time, perform the following checklist:

1. Remove debris or other articles from inside the heater and the area around the heater and its exhaust vent. Make sure the ventilation openings are clear of debris or obstruction. For installations in an enclosed space, make sure openings for combustion and ventilation air are unobstructed.

2. Keep heater area clear and free from combustibles, flammable liquids and chemicals.

3. Check that all water connections are tight.

4. Water must be flowing through the heater during operation. Make sure that pool/spa is filled with water and have pump operating. Check that water flow is unobstructed from the appliance. When operating for the first time or after an extended shutdown, run filter pump for several minutes to clear all air from the system.

SPA TEMPERATURE CAUTION

All safety rules recommended by the U.S. Consumer Product Safety Commission should be observed when using a spa or hot tub, including:

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 above 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 follow the 100°F (38°C) maximum rule.

4. Before entering the spa or hot tub, users should check the water temperature with an accurate thermometer; spa or hot tub thermostats may err in regulating water temperature.

5. Persons with medical history of heart disease, circulatory problems, diabetes or blood pressure problems should obtain their physician’s advice before using spas or hot tubs.

6. Persons taking medications which induce drowsiness, such as tranquilizers, antihistamines or anticoagulants, should not use spas or hot tubs.

OPERATING INSTRUCTIONS

1. STOP! Read the safety information above.

2. Set both pool and spa thermostats to the lowest settings.

The HEATING light comes on and stays on when the burner is firing. This light should be on whenever the burner is on. It blinks when the heater is calling for heat but not firing. If this light is on but the burner fails to come on, one of the “service” lights should come on, indicating a fault in the system.

The SERVICE SYSTEM light indicates that there is insuffi- cient water flow to the heater. If the pump is operating, this usually indicates that the filter and/or skimmers should be cleaned (some filters may require backwashing). If the light remains on after the filter/skimmers have been serviced, the system should be checked by a qualified service technician.

The SERVICE HEATER light indicates a fault in the heater or its controls. If this light comes on, shut down the heater (See TO TURN OFF GAS TO THE APPLIANCE, at left), and have a qualified service technician check the system.

Risk of explosion or fire causing burns or

death if safety interlocks are disabled. DO NOT attempt to

operate heater when SERVICE HEATER light is on or if blower or burner will not start. Instead, follow instructions under “To Turn Off Gas to the Appliance”, at left, and call a qualified service technician to repair unit.

AFTER START-UP

CHECKING WATER FLOW

Fire or flooding hazard. If the unit overheats

and the burner fails to shut off, follow instructions under “To Turn Off Gas to the Appliance”, Page 6, and call a qualified service technician to repair unit.

After start-up, the outlet water pipe should feel slightly warmer than the inlet pipe. If it feels hot, or if you hear the water in the heater boiling, there may not be enough water flow to the appliance. Make sure that the filter is not plugged. If water temperature remains high but the unit continues to operate, turn off the appliance and call your service technician.

SPRING AND FALL OPERATION

If the pool is only used occasionally, lower the pool thermostat to 65°F (18°C). and leave the heater on. This will keep the pool and the surrounding ground warm enough so that the heater should restore the pool to a comfortable temperature within about one day.

COLD WEATHER OPERATION

The heater may be operated in the wintertime, provided air temperatures remain above freezing and the water temperature is not permitted to drop below 65°F (18°C). Extended heater operation with water temperatures below 65°F (10°C) can result in serious damage to the heater and is not covered by warranty.

NOTICE: When starting the heater for the swimming season with a water temperature below 50°F (10°C), the heater may be used to heat the water; however, make sure that the heater operates continuously until the water temperature reaches the heater’s minimum setting of 65°F (18°C).

DO NOT operate this unit outdoors at temperatures below 40°F (4°C).

During cold weather, if there is no danger of freezing, operate the filter pump continuously even if the heater is not operating. If air temperatures are expected to drop below freezing (32°F/0°C), shut down the heater and winterize it (See ”WINTERIZING”, Page 8). Allowing the heater to freeze will void the warranty.

MAINTAINING POOL TEMPERATURE

To maintain pool temperature, make sure that the heater switch and valving are reset to pool settings after using the spa.

ENERGY SAVING TIPS

1. Keep the pool or spa covered when not in use. This will reduce heating costs, reduce water evaporation, conserve chemicals and reduce load on the filtering system.

2. Reduce pool thermostat to 78°F (25°C) or lower; reduce spa temperature to 100°F (38°C).

3. Use a time clock to start the filter pump at 6 a.m. or later. The swimming pool loses less heat after daybreak.

4. For pools used only on weekends, lower the thermostat setting by 10°F to 15°F (5°C to 8°C) during the week to reduce heat loss. A properly sized heater will restore normal temperature within one day.

5. Turn the heater off when the pool will not be used for an extended period.

6. Follow a regular program of preventive maintenance for the heater each new swimming season. Check operation of the heater and its controls.

CARE AND MAINTENANCE

MAINTENANCE INSTRUCTIONS

Risk of fire or explosion from flammable

vapors. Do not store gasoline, cleaning fluids, varnishes,

paints, or other volatile flammable liquids near heater or in the same room with heater.

The following maintenance is recommended every six months and at the start of every swimming season:

1. Inspect the jacket and venting system to make sure that there are no obstructions to the flow of ventilating air or burner exhaust. Check that room air intakes are open and clear of obstructions.

2. Keep the area in and around the heater clear and free from combustible materials, gasoline and other flammable vapors and corrosive liquids.

3. Test the operation of the pressure relief valve by lifting the valve lever.

4. Test for proper operation of the pressure switch. (See “SWITCH SETTINGS” for testing instructions).

5. On enclosed installations with high-temperature Special Gas Vent systems, repeat the Final Installation Check, Page 15. Check for evidence of joint leakage. Make sure that joints have not slipped partially or completely apart. Check pipe and fittings for cracks or breaks.

The combustion air blower is permanently lubricated, and does not require periodic lubrication. The burner does not require maintenance or adjustment by the user. Call a qualified service technician if you suspect that the burner may require maintenance.

WINTERIZING (See Figure 7)

For outdoor heaters in freezing climates, shut the heater down and drain it for winter as follows:

1. Turn off electrical supply to the heater and pump.

2. Close main gas control valve and manual gas valve

(located outside the heater).

3. Open drain cock located on the bottom of the mani-

fold adapter, and drain the heat exchanger and manifold adapter completely. If heater is below pool water level, be sure to close isolation valves to prevent draining the pool (isolation valves are not required and should not be used on heaters installed above pool water level). Assist the draining by blowing out the heat exchanger through the pressure switch fitting with low pressure compressed air (less than 5 PSI or 35 kPa).

Explosion hazard. Purging the system with compressed air can cause components to explode, with risk of severe injury or death to anyone nearby. Use only

a low pressure (below 5 PSI or 35 kPa), high volume blower when air purging the heater, pump, filter, or piping.

4. Remove the Water Pressure Switch. Plug the port in the

manifold to prevent bugs and dirt from getting into the manifold.

5. Drain the plastic inlet/outlet manifold through the out-

let pipe. If the pipe does not drain naturally to the pool, install a drain cock in the outlet pipe to drain the manifold.

6. Cover air inlet grate with a plastic bag to prevent bugs,

leaves, etc., from getting into the heater.

NOTICE: Water trapped in the heater can cause freeze damage. Allowing the heater to freeze voids the warranty.

To return the heater to service after winterizing:

1. Close drain cock and fittings.

2. Before starting the heater, circulate water through the

heater for several minutes until all air noises stop. See also “BEFORE STARTUP” (Page 4) and “CARE AND MAINTENANCE” (above).

OUTDOOR SHELTER INSTALLATION INSTRUCTIONS

This pool heater can only be installed outdoors or in an enclosure that is not normally occupied and does not directly communicate with occupied areas.

Risk of asphyxiation if exhaust is not correctly vented. Follow venting instructions exactly when installing heater. Do not use a draft hood with this heater,

as the exhaust is under pressure from the burner blower and a draft hood will allow exhaust fumes to blow into the room housing the heater. Exhaust venting to the outdoors is required for all outdoor shelter installations.

Risk of explosion if a unit converted to propane gas is installed in a pit or other low spot. Propane is

heavier than air. Do not install the heater using propane in pits or other locations where gas might collect. Consult your local building code officials to determine installation requirements of heater relative to propane storage tanks and filling equipment. Installation must meet the requirements for the Standard for the Storage and Handling of Liquified Petroleum Gases, CAN/CSA B149.2 (latest edition) or ANSI/NFPA 58 (latest edition). Consult local codes and fire protection authorities about specific installation restrictions.

The heater is design certified by CSA International for installation on combustible flooring; in alcoves; basements; in closet or utility rooms (in the U.S.)

INSTALLATION IN A GARAGE OR UTILITY ROOM

In Canada, this must be not normally occupied and must not directly communicate with occupied areas.

Risk of fire and explosion if installed at floor level in an automotive garage or near gasoline or flammable liquid storage. Gasoline fumes are heavier than air and

will settle to floor level in closed spaces. Gasoline fumes and spilled gasoline or other volatile liquids (such as some paints and varnishes) will travel across the floor and can be ignited by a gas appliance. In a utility room or residential garage installation, install the heater with the base at least 18 inches (.5M) above the floor. In a garage, install a rail or wall to protect the heater from physical damage by a moving vehicle.

Provide an adequate ventilation air supply (See Table 2, Page 11). Choose a location that will avoid contamination by chemical fumes.

NOTICE: PROPANE (LPG) fired heaters must not be installed in garages in Massachusetts, by order of the Massachusetts State Fire Marshall. For more information, call the State Fire Marshall’s office.

NOTICE: Combustion air contaminated by corrosive chemical fumes can damage the heater and will void the warranty (See Table 1, Page 11).

HEATER CLEARANCES – OUTDOOR SHELTER (Canada) or INDOOR (U.S.)

The following clearances must be maintained from combustible surfaces:

TOP ...........................6 INCHES (15cm)

ALL SIDES..................6 INCHES (15cm)

VENT .........................6 INCHES (15cm)

The heater is design certified by CSA International for installation on combustible flooring. For installation on carpeting, the heater must be mounted on a metal or wood panel that extends at least three inches (10cm) beyond the base of the heater. If the heater is installed in a closet or alcove, the entire floor shall be covered by the panel.

On an outdoor shelter installation, the exhaust discharges into a vent pipe. Orient the heater so that the vent pipe does not interfere with adjustment of the operating controls. The operating control panel located on top of the jacket can be rotated for convenient access to the control panel.

COMBUSTION AND VENTILATION AIR SUPPLY

For shelter installation, the heater requires air supply openings for ventilation and combustion. The minimum requirements are for two (2) openings: one 12 inches (30cm) from the ceiling for ventilation air and one 12 inches (30cm) from the floor for combustion air, in accordance with the latest edition of ANSI Z223.1, or the National Fuel Gas code, the

CSA B149.1, Natural Gas and Propane Installation Codes, as applicable, and any local codes that may apply.

The minimum net free area in square inches shall be as follows:

OUTDOOR SHELTER VENT INSTALLATION (Canada) or INDOOR INSTALLATION (U.S.)

Always vent the heater to the outdoors.

•Vent it horizontally or vertically using a Special Gas

Vent, (see Table 4, Page 14), or

•Vent it vertically using Type “B” double wall vent con-

nector pipe.

Locate the heater so as to minimize the length of horizontal venting and the number of vent elbows required. Horizontal vent runs must slope up 1/4” per foot (2cm/M) from the heater to allow exhaust condensate to drain and must have a condensate drain as described in the venting installation instructions.

VERTICAL VENTING - NEGATIVE PRESSURE

(See Figures 11 and 12)

Vent the heater vertically in a negative pressure (positive draft) system in accordance with the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and/or CSA B149.1, National Gas and Propane Installation Codes, and local codes. Type “B” Double-wall vent connector is recommended; however single-wall pipe is allowed by the National Fuel Gas Code in some circumstances. Consult your local code official for detailed information. Do not use a draft hood with this heater.

To connect a negative pressure metal gas vent to the heater, order the appropriate Metal Flue Collar from the chart below:

1. See Table 3, below, to determine allowable vent sizes for your heater.

NOTICE: Table 3 is for installations in which the total lateral vent length (that is, the horizontal distance from the flue collar to the main vertical portion of the vent) is less than 1/2 the total vent height (the vertical distance from the flue collar to the vent termination) and which have three or less elbows in the system. For venting systems which do not meet these conditions, consult the National Fuel Gas Code, ANSI Z223.1 (U.S.), or the standards CSA B149.1 and B149.2 (Canada).

2. Install the metal Flue Collar in the Vent Body of the heater (located under the outside vent cover). Fasten the metal Flue Collar to the Vent Body with two #10 sheet metal screws. Use UltraCopper

silicone RTV to seal the

Flue Collar to the Vent Body. Before connecting the metal Flue Collar to the Vent Body, wet a clean cloth or paper towel with isopropyl alcohol (rubbing alcohol) and vigorously wipe the socket of the Vent Body. Immediately wipe the cleaned surfaces dry with a clean cloth or paper towel. Repeat for the exterior of the 4” end of the metal Flue Collar. Attach the metal Flue Collar to the Vent Body using the RTV supplied with the kit, following the vent manufacturer’s instructions (included with kit). Do not use a draft hood with this heater.

3. Attach the vent pipe to the metal Flue Collar with sheet-metal screws.

Risk of fire or asphyxiation if vent is not assembled according to manufacturer’s instructions or if vent parts from different manufacturers are mixed. Vent

parts from different manufacturers ARE NOT interchangeable. Mixing parts from more than one manufacturer may cause leaks or damage to vent. When assembling a vent, pick one manufacturer and be sure that all vent parts come from that manufacturer and are specified by the manufacturer for your system. Follow manufacturer’s instructions, local code requirements, National Fuel Gas Code requirements (U.S.) or standards CSA B149.1 and B149.2 (Canada) carefully during assembly and installation.

4. Install vent pipe so that it can expand and contract

freely as the temperature changes. Support the vent pipe according to applicable codes and the vent manufacturer’s instructions. Pipe support must allow the vent pipe free movement out and back, from side to side, or up and down as necessary, without putting a strain on the heater or vent body. Slope horizontal pipe runs up from the heater at least 1/4” per foot (2cm per meter). Install Listed condensate drains at low points where condensate might collect. Plumb condensate drains to a drain through hard piping or high-temperature tubing such as silicone rubber or EPDM rubber – do not use vinyl or other low temperature tubing. Follow drain manufacturer’s installation instructions.
