CARE AND MAINTENANCE

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 heater panels 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 (if installed).
4. Test for proper operation of the water pressure switch. (See "WATER PRESSURE SWITCH" (page 34) for testing
instructions).
5. On enclosed installations with high-temperature Special Gas Vent systems, repeat the "Final Installation Check,"
27. 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.
Explosion hazard. Any heater installed with restrictive devices in the piping system downstream from the heater, (including
check valves, isolation valves, flow nozzles, or therapeutic pool valving), must have a relief valve installed as described above.
