ASSEMBLY REPLACEMENT INFORMATION.
For Propane (LR) Gas Models Only;
Your water heater is equipped with a Propane (LR) gas con­
trol valve and a main burner assembly with left hand threads
for the following fittings and their connections.
* The connection between the manifold and the gas
control valve (A to B) are left hand threads.
• The connection between the main burner orifice
and the manifold (C to D) are left hand threads.
For ordering these replacement parts, please refer to
the “Repair Parts” section of this manual.
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.
•
OPEN a nearby hot water faucet and leave open to allow for
draining.
• Connect a hose to the drain valve and terminate to an ade­
quate drain.
• 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 attended period, the drain valve should be
left open with hose connected allowing water to terminate
to an adequate drain.
• Close the drain valve.
• Follow instructions in the “Filling The Water Heater” section.
•
Follow the lighting instructions in the “Lighting” section to
restart the water heater.
Temperature-Pressure Relief
Valve Operation
The temperature-pressure relief valve must be manually operated
at least once a year.
,TEM PERATURE.PRESSU RE
RELIEF VALVE
DISCHARGE PIPE
Failure to install and maintain a new properly listed tempera­
ture-pressure relief valve will release the manuracturer from any
claim which might result from excessive temperature or pressure.
AWARNING
If the temperature-pressure relief valve on the appliance
weeps or discharges periodically, this may be due to thermal
expansion. Your water heater may have a check valve
installed in the water line or a water meter with a check
valve. Consult the Sears Service Center for further informa­
tion. Do not plug the temperature-pressure relief valve.
AWARNING
When checking the temperature-pressure relief valve opera­
tion, make sure that (I) no one is in front of or around the
outlet of the temperature-pressure relief valve discharge line,
and (2) that the water manually discharged will not cause any
property damage because the water may be extremely hot.
If after manually operating the valve, it foils 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.
