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.

4.
Locate the hot water (outlet) & cold water (inlet) pipes to the
water heater.
5.
Locate the slit running the length of a section
of pipe
insulation.
6.
Spread the slit open and slip the insulation over the cold
water (inlet) pipe. Apply gentle pressure along the length of
the insulation to ensure that it is fully seated around the pipe.
Also, ensure that the base of the insulation is flush with the
water heater. Once seated, secure the insulation with duct
tape, electrical tape, or equivalent.
7.
Repeat steps 5 and 6 for the hot water (outlet) pipe.
8.
Add additional sections of pipe insulation as needed.

Locate the temperature and pressure relief valve on the water
heater (also known as a T&P relief valve). See Figure 9.
Locate the slit running the length of the T&P relief valve
insulation.
Spread the slit open and fi t the insulation over the T&P relief
valve. See Figure 9. Apply gentle pressure to the insulation
to ensure that it is fully seated on the T&P Relief Valve. Once
seated, secure the insulation with duct tape, electrical tape,
or equivalent. IMPORTANT: The insulationand tape must not
block the discharge opening or hinder access to the manual
relief lever (Figure 9). Ensure a discharge pipe is installed
into the T&P valve discharge opening per the instructions in
this manual.

• 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 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.
