Care and cleaning of the water heater:

DANGER: Before manually operating the

Routine Preventative Maintenance

relief valve, make certain no one will be exposed to the danger of the hot water released by the valve. The water may be hot enough to create a scald hazard. The water should be released into a suitable drain to prevent injury or property damage.

!DANGER: Hotter water increases the potential for Hot Water Scalds.

DANGER: Failure to perform the recommended Routine Preventative Maintenance can harm the proper operation of this water heater, which can cause carbon monoxide dangers, excessive

hot water temperatures and other potentially hazardous conditions.

Properly maintained, your water heater will provide years of dependable trouble- free service.

It is recommended that a periodic inspection of the burner, relief valve, air intake filter, water filter and venting system should be made by service personnel qualified in gas appliance repair.

It is suggested that a routine preventive maintenance program be established and followed by the user.

At least once a year, lift and release the lever handle on the pressure relief valve, located in the hot outlet piping of the water heater, to make certain the valve operates freely. Allow several gallons to flush through the discharge line to an open drain.

NOTICE: If the pressure relief valve on the hot water heater discharges periodically, this may be due to a problem in the water system. Contact the water supplier or your plumbing contractor on how to correct this. DO NOT plug the relief valve outlet.

Rapid closing of faucets or solenoid valves in automatic water using appliances can cause a banging noise heard in a water pipe. Strategically located risers in the water pipe system or water hammer arresting devices can be used to minimize the problem.

Inspect the area around the water heater to ensure a safe operating environment. Keep appliance area clear and free from combustible materials, gasoline and other flammable vapors and liquids.

Ensure the unit has not been damaged. If damage or denting is present, contact a service personnel to verify proper operation.

Check for any abnormal sounds during normal operation of the water heater.

All piping should be checked for gas and/or water leaks. Refer to page 19 of this manual for instructions on leak testing.

The air intake and cold water supply filters should be cleaned monthly. Refer to the “Housekeeping” section for further information.

DO NOT operate the water heater if you feel something is wrong with the unit.

DO NOT allow children to operate or otherwise handle the unit.

Notice: After inspection, maintenance and/or cleaning, ensure proper operation by turning on a hot water faucet.

!DANGER: Shock Hazard

Make sure the electrical power to the water heater is off to avoid potential serious injury or damage to components.

!DANGER: Combustible materials, such as clothing, cleaning materials or flammable liquids, etc., must not be placed against or next to the water heater.
