T & P Valve And Pipe Insulation; Temperature Pressure Relief Valve; Water Piping - Kenmore POWER MISER 153.331712HA Owner's Manual

Figure 15 shows the typical attachment of the water piping to
the water heater. The water heater is equipped with 3/4" NPT
water connections.
NOTE: If using copper tubing, solder tubing to an adapter
before attaching the adapter to the cold water inlet
connection. Do not solder the cold water supply line directly
to the cold water inlet. 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 threaded end of the threaded-to-sweat coupling and
around both ends of the 3/4" NPT threaded nipple. Using
flexible connectors, connect the hot water pipe to the hot
water outlet on the water heater.
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 threaded end of the threaded-to-sweat coupling and
around both ends of the 3/4" NPT threaded nipple. Using
flexible connectors, connect the cold water pipe to the cold
water inlet of the water heater.
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.

RGURE15A.
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 net interfere with the lever of the T & P valve.
Secure all insulation using tape.
Temperature-Pressure Relief Valve
/
Explosion Hazard
• Temperature-pressure relief valve
must comply with ANSI Z21.22
and ASME code.
• Properly sized temperature-
pressure relief valve must be
installed in opening provided.
• Can result in overheating and
excessive tank pressure.
• Can cause serious injury or death.
13
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 and Automatic Gas Shut-off Devices for Hot Water Supply
Systems, ANSI Z21.22 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 safe operation of the water heater, the relief valve must not
be removed from its designated opening nor plugged.
