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 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.

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.

                      

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 28.

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 a

qualified service agency for further information. Do not plug the

temperature-pressure relief valve.

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 power 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.

 

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  “Lighting

Instructions” in this manual to restart the water heater.
