Care and cleaning of the water heater.
Routine Preventative Maintenance
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, water filter and flue terminal
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.

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.

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.

service personnel to verify proper
operation.
