Preventive Maintenance
!
WARNING:
Failure to perform routine preventive maintenance
can prevent the water heater from operating
properly. Improper operation can cause carbon
monoxide dangers, excessive water temperatures,
and other potentially hazardous conditions resulting
in death, personal injury, and/or product damage.
Properly maintaining your water heater will ensure
dependable, trouble-free service�
User Preventive Maintenance
Establish and follow a routine preventive maintenance
program� The following suggested items should be
included in your program�
Monthly check and clean the water filter� See “Water Filter
Cleaning” on page 17�
!
WARNING:
Hot water is released during manual operation of
the relief valve. Make sure all people and animals
are clear from the area before performing this
check to prevent death, personal injury, and/or
property damage from hot drain water.
Annually check the operation of the pressure-relief valve�
Lifting the lever handle on the pressure-relief valve opens
the valve to flush hot water through the discharge line to
the drain� After several gallons have drained, release the
lever handle to close the valve and stop draining�
NOTICE:
If the pressure relief valve on the hot water heater
discharges periodically, this may indicate a problem
in the water system. Contact the water supplier or a
plumbing contractor to correct the problem. DO NOT
plug the relief valve outlet.
• Inspect and keep the area around the water
heater clear and free of flammable materials,
such as gasoline and other flammable vapors and
liquids.
• Visually inspect the water heater for damage and/
or denting. If present, contact a service personnel
to verify proper operation.
• Check for abnormal sound during normal
operation (e.g., hissing or banging noises).
Contact a qualified service technician or plumbing
contractor.
• Check all gas and water pipes for leaks. See
page 54.
NOTICE:
– DO NOT operate the water heater if you feel
something is wrong with the unit.
