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.

Relief Valve
Explosion

Temperature-pressure
relief valve
must comply with ANSI Z21.22 -
CSA 4.4 and ASME code.
Properly sized temperature-relief
valve must be installed in opening
provided.
Can result
in overheating
and
excessive tank pressure.
Can cause serious injury or death.
This
heater
_s 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.
T & P Valve and Pipe Insulation
Remove
insulation
for T & P valve
and pipe connections
from
carton.
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.
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.
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,
or at
any distance
below the structural
floor.
Be certain
that no contact
