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 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). Turn switch on heater gas valve to OFF. 3. Open drain cock located on the bottom of the manifold 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). WARNING 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 outlet 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). INSTALLATION INSTRUCTIONS WARNING Risk of fire, explosion, or asphyxiation if heater is improperly installed, adjusted, serviced or maintained. These instructions are for licensed, certified, trained and experienced installers only. Be sure your installer or service technician holds all required licenses or certification for your area. Attempts by unqualified persons to service or repair this heater are dangerous and could be fatal. PRE-EXISTING VENT SYSTEMS If you are considering connecting this heater to a pre-existing vent system, make sure that the vent system meets the appropriate venting requirements as given in this manual, Pages 9-15. If not, replace the vent system. DO NOT use a draft hood with this heater. PUTTING THE HEATER INTO SERVICE If the heater is installed below the level of the pool, or more than two feet above pool level, the pressure switch setting should be adjusted. See PRESSURE SWITCH, in the MAINTENANCE section. Before putting the heater into service for the first time, follow the instructions under “BEFORE START-UP” (page 4) in the front of this manual. Check for proper operation of the heater by following the steps under “OPERATING INSTRUCTIONS.” Damage to equipment caused by improper installation or repair will void the warranty. 8 OUTDOOR INSTALLATION INSTRUCTIONS TOP ...................................3 ft. (1 m) For heaters located outdoors, using the built-in stackless venting system. WARNING Risk of explosion if a unit burning 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 of the Standard for the Storage and Handling of Liquid Petroleum Gases, ANSI/NFPA 58 (latest edition) in the U.S., or CAN/CSA B149.2 (latest edition) in Canada. Consult local codes and fire protection authorities about specific installation restrictions. Locate the heater on a level surface in an open area that is protected from drainage or run-off. Install the heater in an area where leaves or other debris will not collect on or around the heater. This heater is designed for outdoor installation. However, to avoid damage to the electronic components in the heater, take care to prevent prolonged...
