T & P Valve And Pipe Insulation; Temperature-Pressure Relief Valve - Kenmore 153.318032 Owner's Manual

3. look at the top cover of the water heater. The cold water inlet
is marked cold. Put two or three turns of teflon tape around
the threaded end of the threaded-to-sweat coupling and
around both ends of the 3/4" threaded nipple using flexible
connectors, connect the cold water pipe to the cold water inlet
of the water heater.
NOTE: Your water heater is super insulated to minimize
heat loss from the tank. Further reduction in heat loss can
be accomplished by insulating the hot water lines from the
water heater.

T & P Valve and Pipe Insulation
remove insulation for T & P valve and pipe connections from
carton.
fit pipe insulation over the incoming cold water line and the hot
water line. Make sure that the insulation is against the top cover
of the heater.
fit T & P valve insulation over valve. Make sure that the insulation
does not interfere with the lever of the T & P valve.
Secure all insulation using tape.
FIGURE 9.

Temperature-Pressure Relief Valve

This heater is provided with a properly certified combination
temperature - pressure relief valve by the manufacturer.
The valve is certified by a nationally recognized testing laboratory
that maintains periodic inspection of production of listed
equipment of materials as meeting the requirements for relief
valves for Hot Water Supply Systems, ANSI Z21.22 • CSA 4.4,
and the code requirements of ASME.
If replaced, the valve must meet the requirements of local codes,
but not less than a combination temperature and pressure relief
valve certified as indicated in the above paragraph.
The valve must be marked with a maximum set pressure not to
exceed the marked hydrostatic working pressure of the water
heater (150 psi = 1,035 kPa) and a discharge capacity not less
than the water heater input rate as shown on the model rating
plate. (for electric heaters, watts x 3.412 equals btu/hr input
rate). for safe operation of the water heater, the relief valve must
not be removed from its designated opening nor plugged.
The temperature-pressure relief valve must be installed directly
into the fitting of the water heater designed for the relief valve.
Position the valve downward and provide tubing so that any
discharge will exit only within 6 inches (153 mm) above, or at any
distance below the structural floor. be certain that no contact is
made with any live electrical part. The discharge opening must
not be blocked or reduced in size under any circumstances.
Excessive length, over 30 feet (9.14 m), or use of more than
four elbows can cause restriction and reduce the discharge
capacity of the valve.
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.
