Other Pool & Spa

Types

Water Temp. (Deg. F) 68 to 88 89 to 104 68 to 104

pH 7.3 to 7.4 7.3 to 7.4 7.6 to 7.8

Total Alkalinity (PPM) 120 to 150 120 to 150 80 to 120

Calcium Hardness (PPM) 200 to 300 150 to 200 200 to 400

Salt (PPM) 4500 MAXIMUM 4500 MAXIMUM 4500 MAXIMUM

Free Chlorine (PPM)* 2 to 3 2 to 3 2 to 3

Total Dissolved Solids (PPM) 3000 MAXIMUM** 3000 MAXIMUM** 3000 MAXIMUM**

* Free Chlorine MUST NOT EXCEED 5 PPM!

** In salt water chlorinated pools, the total TDS can be as high as 6000 ppm.

• Occasional chemical shock dosing of the pool or spa water should not damage the

heater providing the water is balanced.

• Automatic chemical dosing devices and salt chlorinators are usually more efficient

in heated water, unless controlled, they can lead to excessive chlorine level which can damage your heater, and which is not covered under warranty. A check valve should be installed between the heater outlet and a chlorinator or other chemical dosing device.

• Further advice should be obtained from your pool or spa builder, accredited pool

shop, or chemical supplier for the correct levels for your water.

WARNINGS—Pay Attention to These Terms

DANGER:

WARNING:

CAUTION:

NOTE:

DANGER: Failure to install the draft hood on indoor

installations and properly vent the heater to the outdoors as outlined in the Venting section of this manual can result in unsafe operation of the heater. To avoid the risk of fire, explosion, or asphyxiation from carbon monoxide, never operate this heater unless it is properly vented and has an adequate air supply for proper operation. Be sure to inspect the vent system for proper installation at initial start-up; and at least annually thereafter. Refer to the Maintenance section of this manual for more information regarding vent system inspections.

DANGER: Make sure the gas on which the heater will operate is the same type as that specified on the heater rating plate.

DANGER: When servicing or replacing components that are in direct contact with the water, be certain that:

• There is no pressure in the heater. (Pull the release on the relief valve. Do not depend on the pressure gauge reading).

• The heater water is not hot.

• The electrical power is off.

WARNING: All venting types must be of the same material or product throughout the entire exhaust installation to ensure proper securing and sealing.

Indicates the presence of immediate hazards which will cause severe personal injury, death or substantial property damage if ignored.

Indicates the presence of hazards or unsafe practices which could cause severe personal injury, death or substantial property damage if ignored.

Indicates the presence of hazards or unsafe practices which could cause minor personal injury or product or property damage if ignored.

Indicates special instructions on installation, operation, or maintenance which are important but not related to personal injury hazards.

WARNING: Both natural gas and propane have an odorant added to aid in detecting a gas leak. Some people may not physically be able to smell or recognize this odorant. If you are unsure or unfamiliar with the smell of natural gas or propane, ask your local gas supplier. Other conditions, such as "odorant fade," which causes the odorant to diminish in intensity, can also hide, camouflage, or otherwise make detecting a gas leak by smell more difficult.

WARNING: UL recognized fuel gas detectors are recommended in all enclosed propane and natural gas applications wherein there is a potential for an explosive mixture of fuel gas to accumulate and their installation should be in accordance with the detector manufacturer's recommendations and/or local laws, rules, regulations, or customs.

WARNING - CALIFORNIA PROPOSITION 65: This product contains chemicals known to the

State of California to cause cancer, birth defects or other reproductive harm.

WARNING: This product must be installed by a licensed plumber or gas fitter when installed within the Commonwealth of Massachusetts.

WARNING: Altering any Raypak pressure vessel by installing replacement heat exchangers, tube bundle headers, or any ASME parts not manufactured and/or approved by Raypak will instantly void the ASME and/or CSA ratings of the vessel and any Raypak warranty on the vessel. Altering the ASME and/or CSA ratings of the vessel also violates national, state, and local approval codes.

WARNING: Do not install within 3 feet of a heat pump or an outdoor condensing unit. Strong air intake from this type of equipment can disturb the combustion process and cause damage or personal injury.

WARNING: Do not use this heater if any part has been under water. Immediately call a qualified service technician to inspect the heater and to replace any part of the control system and any gas control which has been under water.

OWNER'S OPERATING INSTRUCTIONS

FOR YOUR SAFETY - READ BEFORE OPERATING WARNING: IF YOU DO NOT FOLLOW THESE INSTRUCTIONS EXACTLY, A FIRE OR EXPLOSION MAY RESULT, CAUSING PROPERTY DAMAGE, PERSONAL INJURY OR LOSS OF LIFE.

INTRODUCTION

Your pool/spa heater has been designed for years of safe and reliable pool/spa water heating. It is available with electronic ignition. This manual provides installation, operation, maintenance, and service information for these heaters.

If your heater has been installed correctly, operating the heater is an easy task. The upper front panel of the heater contains the control center that allows you to turn the heater On or Off and adjust the temperature settings for the pool or spa. The temperature range is factory set from 50°F (18°C) to 104°F (40°C). See figure above for location of toggle switch to turn the heater On and Off. Section 4 of this manual contains more details about the use of the controls in the Control Adjustments subsection (page 34).

SECTION 1 - START-UP PROCEDURE

1. Clean air louvers of dust, lint and debris.

2. Keep heater area clear and free from com-

bustibles, flammable liquids and chemicals.

3. Verify that the flow of combustion and ventilation

air is not obstructed.

4. Water must be flowing through the heater during

operation. Ensure that the system is filled with water and the pump is operating. Double check for any water leaks.

5. Purge air from the gas line. Insufficient purging

may keep the heater from lighting on the first try.

6. Double check gas connections, make sure no

leaks are present. Use soapy water to inspect.

7. Double check incoming electrical power, verify suf-

ficient output voltage to the heater.

8. The unit comes wired for 240V/1ph/60Hz power. If

the supply voltage is nominally 120V/1ph/60Hz, switch the blower harness located inside the cabinet (see wiring diagram).

9. If installed indoors, make sure flue gases are vent-

ed properly, and that combustion and makeup air openings are adequate.

10. Locate and turn the gas valve ON.

11. Locate the plugged bleedle valve off the right side

of the gas valve.

12. Remove the bleedle plug and connect a manome-

ter to the valve.

13. Locate and flip the display lid upwards.

14. Turn the heater on, by pressing the ON/OFF tog-

gle switch on the front display.

15. Set the mode to either SPA or POOL.

16. If the set point is higher than the current temperature, the heater will begin its startup sequence.

17. The ignition control will verify that the blower air switch is open before starting the blower. Once proven open, the blower will be powered to start the ignition sequence. Verify suction pressure matches the table below, Blower Suction Pressure, for your model heater during the prepurge period.

18. Once the blower air switch proves, a 45 second pre-purge period will begin to purge residual gases from the combustion chamber.

Model Elevation Blower Suction

0-2000 ft. -3.5 to -3.8 "WC

259

409

2000-5000 ft. -3.1 to -3.6 "WC

5000-7000 ft. -2.8 to -3.2 "WC

0-2000 ft. -3.7 to -4.0 "WC

2000-5000 ft. -3.3 to -3.8 "WC

5000-7000 ft. -3.0 to -3.4 "WC

Blower Suction Pressure

19. Once the pre-purge period ends, the igniter will begin to spark just prior to the gas valve opening. The gas valve will open for a 4 second trial for ignition. If flame is proven, the heater will operate to meet heat demand. If flame is not proven, the heater will enter a post-purge period and then retry the ignition cycle or lockout, depending on the heater configuration.

20. Once gas is flowing, the manometer reading will drop to -0.40” +/- .1” WC. See the instructions on page 40 for adjusting the valve manifold pressure if the reading is not within tolerance.

21. Visually check through the sight glass that the heater is on and heating. A yellowish glow coming from the refractory indicates that the heater is running. The flame should be a blueish color.

22. Remove the manometer and replace with bleedle plug.

23. Reinstall front door panel and knurled screw holding the door in place.

24. Feel the inlet and outlet pipes. Outlet pipe should be only slightly warmer than the inlet. It should not be hot.

SECTION 2 - CAUTION

Elevated water temperature can be hazardous. The U.S. Consumer Product Safety Commission has these guidelines:

1. Spa 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.

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 drowsiness, such as tranquilizers, antihistamines, or anticoagulants, should not use spas or hot tubs.

SECTION 3 - MAINTENANCE AND CARE PROCEDURES

WARNING: Check the heater for possible rodent

nests after long periods of non-use.

To be followed one month after start-up and then semiannually.

1. Inspect and operate all controls, gas valve and

pressure relief valve.

2. On indoor heaters, clean room intake openings to

ensure 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.

3. Keep area around heater clear and free from com-

bustible materials, gasoline and other flammable and corrosive vapors and liquids.

IF HEATER WILL NOT FIRE:

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 thermometer; spa or hot tub thermostats may err in regulating water temperatures by as much as 4°F (2.2°C).

If you have no electrical power, it may be that your "circuit breaker" has tripped. Try re-setting it.

If you have electrical power but the heater will not fire check the following or see Troubleshooting section:

1. The time clock must be in the "ON" position.

2. Your pump strainer basket may be full. If so remove debris.

3. 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).

4. The pump may have lost its prime and be running 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 its normal flow rate.

WARNING: Should overheating occur or the gas supply fail to shut off, turn off the manual gas control to the heater.

CAUTION: Propane gas is heavier than air and will settle on the ground. Since propane can accumulate in confined areas, extra care should be exercised when lighting propane heaters.

POOL & SPA WATER CHEMISTRY

Chemical imbalance can cause severe damage to your heater and associated equipment. Maintain

your water chemistry according to the chart on page 2. If the mineral content and dissolved solids in the water become too high, scale forms inside the heat exchanger tube, reducing heater efficiency and damaging the heater. If the pH drops below 7.2, this will cause corrosion of the heat exchanger and severely damage the heater. Heat exchanger damage resulting from

chemical imbalance is not covered by the warranty.

COLD CLIMATE: Prolonged operation with water

temperatures below 50°F is not recommended. When starting the heater with water temperatures below 50°F, operate the heater continuously until higher temperatures 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

AUTOMATIC CHLORINATORS AND CHEMICAL FEEDERS

All chemicals must be introduced and completely diluted into the pool or spa water before being circulated through the heater. Do not place sanitizing chemicals in the skimmer. High chemical concentrations will result when the pump is not running (e.g. 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. A check valve should be installed between the heater outlet and the chlorinator.

See plumbing diagrams on page 30 and 31.

NOTE: High chemical concentrates from feeders and

chlorinators that are out of adjustment will cause rapid corrosion to the heat exchanger. Such damage is not

covered under the warranty.

COLD WEATHER OPERATION

IMPORTANT FREEZE INFORMATION

Heaters installed outdoors in freezing climate areas may be shut down for the winter. Observe the following procedure for winterizing the heater:

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

cal supply to the heater.

2. Open the drain valve located on the inlet/outlet

header (at the lowest point). Pull the PRV handle upwards to allow air in while the water drains through the valve.

MODERATE CLIMATE: Heater operation can continue during short-term cold spells. When temperatures are between 0°F and 32°F, 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 operation is a must. Additional protection may be required. The heater is not warranted against freeze-ups.

SECTION 3 - INSTALLATION INSTRUCTIONS

CALIFORNIA PROPOSITION 65 WARNING: This product contains chemicals known to the State of California

to cause cancer, birth defects or other reproductive harm.

WARNING: This unit contains refractory ceramic fiber (RCF) insulation in the combustion chamber. RCF, as manufactured, does not contain respirable crystalline silica. However, following sustained exposure to very high temperatures (>2192°F), the RCF can transform into crystalline silica (cristabolite). The International Agency for Research on Cancer (IARC) has classified the inhalation of crystalline silica (cristabolite) as carcinogenic to humans.

When removing the burner or heat exchanger, take precautions to avoid creating airborne dust and avoid inhaling airborne fibers. When cleaning spills, use wet sweeping or High Efficiency Particulate Air (HEPA) filtered vacuum to minimize airborne dust. Use feasible engineering controls such as local exhaust ventilation or dust collecting systems to minimize airborne dust. Wear appropriate personal protective equipment including gloves, safety glasses with side shields, and appropriate NIOSH certified respiratory protection, to avoid inhalation of airborne dust and airborne fiber particles.
