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 “Locating the New Water Heater” 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, 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 113.
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 113.
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 service agency 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. Turn the gas control knob 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, see page 29 under “Lighting
Instructions” to restart the water heater.
