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.

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 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. A llow 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.
