Installation / Operation Instruction Manual

Maintenance continued-
The following maintenance should be performed by a qualified service
technician at the minimum periodic intervals suggested below. In some
installations, the maintenance interval may be more frequent depending on
the amount of use and the operating conditions of the water heater.
Regular inspection and maintenance of the water heater will help to insure safe
and reliable operation.
1. Annually, check the operation of the thermostat(s).
2. Bi-annually, check the seal around the heating elements for leaks. If there is
any sign of leaking, disconnect the power supply to the water heater and
contact the plumbing professional that installed this water heater or a
qualified service technician.
3. At least once a year, check the combination temperature and pressure relief
valve to insure that the valve has not become encrusted with lime. Lift the
lever at the top of the temperature-pressure relief valve several times until
the valve seats properly without leaking and operates freely.
4. If the combination temperature and pressure relief valve on the appliance
discharges periodically, this may be due to thermal expansion in a closed
water supply system. Contact the water supplier or local plumbing inspector
on how to correct this situation. Do not plug the combination temperature
and pressure relief valve outlet for any reason.
5. Monthly, drain off a gallon of water from the water heater to remove silt and
sediment.
6. A combination sacrificial anode rod/hot water outlet nipple has been installed
to extend tank life. The anode rod should be inspected periodically (every 2
years) and replaced when necessary to prolong tank life. Water conditions
in your area will influence the time interval for inspection and replacement of
the anode rod. Contact the plumbing professional who installed the water
heater or the manufacturer listed on the rating plate for anode replacement
information. The use of a water softener may increase the speed of anode
WARNING
When lifting lever of temperature-pressure relief valve, hot water will be
released under pressure. Be certain that any released water does not
result in bodily injury or property damage.
WARNING!: THIS WATER MAY BE HOT.
