Housekeeping
Vacuum around base of water heater for dust, dirt, and lint on a
regular basis.
INSTALLED IN SUITABLE AREA: To insure sufficient ventilation
and combustion air supply, proper clearances from the water
heater must be maintained. See Facts to Consider About the
Location section. Combustible materials such as clothing,
cleaning materials, or flammable liquids, etc. must not be
placed against or adjacent to the water heater which can cause
a fire.
Anode Rod Inspection
The anode rod is used to protect the tank from corrosion. Most
hot water tanks are equipped with an anode rod. The submerged
rod sacrifices itself to protect the tank. Instead of corroding the
tank, water ions attack and eat away the anode rod. This does
not affect the water’s taste or color. The rod must be maintained
to keep the tank in operating condition.
Anode deterioration depends on water conductivity, not
necessarily water condition. A corroded or pitted anode rod
indicates high water conductivity and should be checked and/or
replaced more often than an anode rod that appears to be intact.
Replacement of a depleted anode rod can extend the life of
your water heater. Inspection should be conducted by a qualified
technician. At a minimum, the anode(s) should be checked
annually after the warranty period.
Temperature-Pressure Relief Valve Operation
The temperature-pressure relief valve must be manually
operated at least once a year.
When checking the temperature-pressure relief valve operation,
make sure that (1) no one is in front of or around the outlet of
the temperature-pressure relief valve discharge line, and (2) that
the water discharge will not cause any property damage, as the
water may be extremely hot, see Figure 25.
FIGURE 25.
If after manually operating the valve, it fails to completely reset
and continues to release water, immediately close the cold
water inlet to the water heater, follow the draining instructions,
and replace the temperature-pressure relief valve with a new
one.
If the temperature-pressure relief valve on the appliance weeps
or discharges periodically, this may be due to thermal expansion.
You may have a check valve installed in the water line or a water
meter with a check valve. Consult Maytag Customer Service
at 1-800-788-8899 for further information. Do not plug the
temperature-pressure relief valve.
Draining
The water heater should be drained if being shut down during
freezing temperatures. Also periodic draining and cleaning of
sediment from the tank may be necessary.
• Turn the gas control knob to the “OFF” position.
• CLOSE the cold water inlet valve to the water heater.
