Filling The Water Heater - Kenmore 153.331762 Use & Care Manual

FIGURE 17.
No valve or other obstruction is to be placed between the
relief valve and the tank. Do not connect tubing directly
to discharge drain unless a 6 inch air gap is provided. To
prevent bodily injury, hazard to life, or property damage, the
relief valve must be allowed to discharge water in quantities
should circumstances demand. If the discharge pipe is not
connected to a drain or other suitable means, the water flow
may cause property damage.
CAUTION
Water Damage Hazard
•
Pressure Relief Valve discharge pipe must
terminate at adequate drain.
The Discharge Pipe:
• Shall not be smaller in size than the outlet pipe size of the
valve, or have any reducing couplings or other restrictions.
• Shall not be plugged or blocked.
• Shall not be exposed to freezing temperatures.
• Shall be of material listed for hot water distribution.
• Shall be installed so as to allow complete drainage of
both the relief valve and the discharge pipe.
• Must terminate a maximum of six inches above a floor
drain or external to the building. In cold climates, it is
recommended that the discharge pipe be terminated at
an adequate drain inside the building.
• Shall not have any valve or other obstruction between
the relief valve and the drain.
Once the boiler is installed and filled with water and the system
is pressurized, manually test the operation of the pressure
relief valve. See the maintenance section of this manual for
instructions.
DANGER
The Temperature-Pressure Relief valve must be manually
operated at least twice a year. Caution should be taken to
ensure that (1) no one is in front of or around the outlet of the
Temperature-Pressure Relief valve discharge line, and (2) the
water manually discharged will not cause any bodily injury or
property damage because the water may be extremely hot. 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 in this
manual, and replace the Temperature-Pressure Relief valve with
a properly rated/sized new one.
Note: The purpose of a Temperature-Pressure Relief valve is to
prevent excessive temperatures and pressures in the storage
tank. The T&P valve is not intended for the constant relief of
thermal expansion. A properly sized thermal expansion tank must
be installed on all closed systems to control thermal expansion,
see Closed Water Systems and Thermal Expansion on page 23.
If you do not understand these instructions or have any questions
regarding the Temperature-Pressure Relief valve call the toll
free number listed on the back cover of this manual for technical
assistance.

Filling the water Heater

Never use this water heater unless it is completely full of water.
To prevent damage to the tank, the tank must be filled with water.
Water must flow from the hot water faucet before turning "ON"
gas to the water heater.
To fill the water heater with water:
• Close the water heater drain valve by turning the handle to
the right (clockwise). The drain valve is on the lower front of
the water heater.
• Open the cold water supply valve to the water heater.
noTE: The cold water supply valve must be left open
when the water heater is in use.
• To insure complete filling of the tank, allow air to exit by
opening the nearest hot water faucet. Allow water to run until
a constant flow is obtained. This will let air out of the water
heater and the piping.
• Check all water piping and connections for leaks. Repair as
needed.
