NOTE: Toprotect against untimely c orrosion o f
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.

relief valve
must comply
with ANSI Z21.22

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.
