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, and at a minimum 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.
FIGURE 30.
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 30.
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
your local water supplier or Maytag Customer Service (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.
1. Set the blower switch to the "OFF" position.
2. CLOSE the cold water inlet valve to the water heater.
3. OPEN a nearby hot water faucet and leave open to allow for draining.
4. Connect a hose to the drain valve and terminate to an adequate drain.
5. OPEN the water heater drain valve to allow for tank draining.
NOTE: If the water heater is going to be shut down and
drained for an extended period, the drain valve should be
left open with hose connected allowing water to terminate
to an adequate drain.
6. CLOSE the drain valve.
7. Follow instructions in the "Filling The Water Heater" section.
8. Follow the lighting instructions on the label or see page 23 under
"Operating Instructions" to restart the water heater.
DRAIN VALVE WASHER REPLACEMENT
(See Figure 31)
1. Turn "OFF" gas supply to water heater.
2. Follow "Draining" instructions.
3. Turning counterclockwise (
screw handle.
4. Remove the washer and put the new one in place.
5. Screw the handle and cap assembly back into the drain valve and
retighten using a wrench. DO NOT OVER TIGHTEN.
6. Follow instructions in the "Filling The Water Heater" section.
7. Check for leaks.
8. Follow the lighting instructions in the "Operating Instructions" section
to restart the water heater.
SERVICE
If a condition persists or you are uncertain about the operation of the
water heater contact Maytag Customer Service at 1-800-788-8899
for an authorized servicer.
