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 ow 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 ammable
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 on page 15 for testing
instructions.
5. For enclosed installations, repeat the FINAL INSTALLATION CHECK, page 39. Check for evidence of joint leakage.
Make sure that joints have not slipped partially or completely apart. Check pipe and ttings for cracks or breaks. The
