Draining And Flushing; Thermostat Removal/Replacement - Kenmore 153.329266 Use & Care Manual

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.
Failure to install and maintain a new properly listed temperature-
pressure relief valve wilt release the manufacturer from any claim
which might result from excessive temperature or pressure.
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 your local
Sears Service Center for further information. Do not plug the
temperature-pressure relief valve.

Improper installation and use may result
in property damage.
• Fill tank with water before operation.
Never use this water heater unless it is completely full of water.
To prevent damage to the tank and heating element, the tank
must be filled with water. Water must flow from the hot water
faucet before turning "ON" power.

• Burn hazard
• Hotwater discharge.
• Keep hands clear of drain
valve discharge.
It is recommended that the tank be drained and flushed every 6
months to remove sediment which may build up during operation.
The water heater should be drained if being shut down during freezing
temperatures. To drain the tank, perform the following steps:
• Before removing any access
panels or servicing the water
heater, make sure the electrical
supply to the water heater is
turned "OFF".
• Failure to do this could result in
death, serious bodily injury, or
property damage.
1. Turn off power to the water heater.
2. Open a nearby hot water faucet until the water is no longer
hot.
3. Close the cold water inlet valve.
4. Connect a hose to the drain valve and terminate it to an
adequate drain or external to the building.
5. Open the water heater drain valve and allow all of the water
to drain from the tank. Flush the tank with water as needed
to remove sediment.
6. Close the drain valve, refill the tank, and restart the heater as
directed in this manual. CAUTION: Do not turn on power to
the water heater unless it is completely filled with water.
If the water heater is going to be shut down for an extended
period, the drain valve should be left open.
IMPORTANT: Condensation may occur when refilling the tank
and should not be confused with a tank leak.
• Before removing any access
panels or servicing the water
heater, make sure the electrical
supply to the water heater is
turned "OFF".
• Failure to do this could result in
death, serious bodily injury, or
property damage.
1. Turn "OFF" the electrical power to the water heater at the
junction box.
2. Remove the access panel and fold the insulation back to
expose the thermostat.
3. Lift out the tab as shown below to unctip the terminal cover
