Fit pipe insulation
over the incoming
cold water
line and the hot
water line. Make sure that the insulation
is against
the top cover

® Temperature-pressure
relief valve
must comply with ANSI Z21.22 ,
0SA4.4.
" Properly sized temperature-relief
valve must be installed in opening
provided.
Can
result
in overheating
and
excessive tank pressure.
_, Can cause seriousinjury or death.
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.
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
is
made with any live electrical
part.
The discharge
opening
must
not be blocked
or reduced
in size
under
any
circumstances.
Excessive
length,
over
30 feet (9.14
m), or use of more than
four
elbows
can
cause
restriction
and reduce
the discharge
capacity
of the valve.
Water Damage
Hazard
o Temperature-pressure
relief valve
discharge
pipe must terminate
at adequate
drain.
I0
No valve
or other obstruction
is to be placed
between
the relief
valve and the tank.
Do not connect
tubing
directly
to discharge
drain
unless
a 6 inch air gap is provided.
To prevent
bodily
injury, hazard
to life, or property
damage,
the relief valve
must
be allowed
to discharge
water in quantities
should
circumstances
demand.
If the discharge
pipe is not connected
to a drain or other
suitable
means,
the water flow may cause property
damage.
