Preventive Maintenance - Rheem RTGH-95XLP-2 Use And Care Manual

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.
Check and clean the water filter monthly. 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
annually. 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.
CARING FOR YOUR WATER HEATER
Relief Valve
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 if abnormal sounds are
noted.
• Check all gas and water pipes for leaks. See page 56.
NOTICE:
– DO NOT operate the water heater if you feel
something is wrong with the unit.
– DO NOT allow children to operate or handle
the unit.
• After inspections, maintenance, and/or cleaning, ensure
proper operation by turning on a hot water faucet.
