SECTION X: MAINTENANCE

WARNING

Always turn off the electrical power supply, the manual gas valve, and the manual water control valve whenever servicing this appliance.

KEEP THE APPLIANCE AREA CLEAR AND FREE FROM COMBUSTIBLE MATERIALS, GASOLINE, AND OTHER FLAMMABLE VAPORS AND LIQUIDS.

The EVERHOTwater heater should be checked annually by a qualified technician. Regular maintenance will keep the water heater operating efficiently and help to assure reliable operation and a long service life.

1.Remove and clean the inlet water filter screen.

2.Visually inspect the burner flames. The flame must burn with a clear blue, stable flame. Refer to figure 13, “Burner Flame Appearance” for satisfactory flame appearance. If the burner flame appearance is not satisfactory or debris is visible on the burners, remove and clean with a vacuum cleaner.

3.Inspect entire venting system and vent terminal. Make sure all the venting connections are tight and the gaskets are in good condition. Check the vent terminal openings for blockage and clean, if necessary. Keep shrubs and vegetation clear of the vent terminal.

4.All electric motors are permanently lubricated and do not need oiling. Remove the combustion air blower and clean wheel and housing with soft brush or vacuum.

5.If the “LC” code has been flashing on the remote display, the heat exchanger will need flushing to remove lime and scale deposits. Refer to the “Flushing Procedure for Lime Scale Removal…” in Section X, “Maintenance”.

6.Check operation of the pressure relief valve. To check the relief valve, lift the lever at the end of the valve several times. The valve should seat properly and operate freely. If water does not flow, remove and inspect for obstructions or corrosion. Replace with a new valve of the recommended size as necessary. A thorough inspection of the valve should be performed at least every three years by removing the pressure relief valve from the outlet piping. Do not attempt to repair the valve, as this could result in improper operation and explosion of the heat exchanger and piping. In areas with poor water conditions, it may be necessary to inspect the pressure relief valve more often than the recommended maintenance schedule.
