Temperature-Pressure Relief Valve - Kenmore 153.331762 Use & Care Manual

TYPICAl INSTAllATION
FIGURE 16.
noTE: If using copper tubing, solder tubing to an adapter
before attaching the adapter to the water connections. Do
not solder the water lines directly to the water connections
on the tank. It will harm the dip tube and damage the tank.
• Look at the top cover of the water heater. The water outlet is
marked "HOT". Put two or three turns of teflon tape around
the exposed end of the NPT threaded nipple. Connect the hot
water pipe to the hot water outlet on the water heater. Please
note that adapters may be needed to match existing piping.
• Look at the top of the water heater. The cold water inlet
is marked "COLD". Put two or three turns of teflon tape
around the exposed end of the NPT threaded nipple.
Connect the cold water pipe to the cold water inlet of the
water heater. Please note that adapters may be needed
to match existing piping.
noTE: This 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.

TEMPERATURE-PRESSURE RElIEF VAlVE

This heater is provided with a properly certified combination
temperature - pressure relief valve by the manufacturer.
T h e v a l v e i s c e r t i f i e d b y a n a t i o n a l l y r e c o g n i z e d
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 = 1,035kPa) and a discharge capacity
not less than the water heater input rate as shown on the
model rating plate.
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 a floor drain or external to the building,
see Figure 16. 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.
