T & P Valve And Pipe Insulation; Temperature-Pressure Relief Valve - Kenmore 153.326164 Use & Care Manual

NOTE: To protect against untimely corrosion of hot and cold
water fittings, it is strongly recommended that di-electric
unions or couplings be installed on this water heater when
connected to copper pipe.
1.
Look at the top cover of the water heater. The hot 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" threaded nipple. Using
flexible connectors, connect the hot water pipe to the hot
water outlet of the water heater.
2. 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 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.

Temperature-pressure relief
valve must comply with ANSI
Z21.22-CSA 4.4 and ASME
code.
• Properly sized temperature-
pressure relief valve must be
installed in opening provided.
• Do not plug, block, or cap the
discharge line.
• Failure to follow this warning
can result in excessive tank
pressure, serious injury or
death.
11
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 tess
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 wilt exit only within 6 inches (153 mm) above, or at any
distance below the structural floor. Be certain that no contact is
