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. On indoor heaters, 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 flam- mable vapors and corrosive liquids.
3.On heaters equipped with a pressure relief valve, test the operation of the valve by lifting the valve lever.
4.Test for proper operation of the pressure switch. (See “SWITCH SETTINGS” for testing instructions).
5.On indoor installations with
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 mani- fold adapter completely. If heater is below pool water level, be sure to close isolation valves to prevent drain- ing 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), 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.

FIGURE 7: Winterizing
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).
