• 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.
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.
Position the valve downward
and provide tubing so that any
discharge will exit only within 6 inches (15.2 cm) 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
• Temperature-pressure relief valve discharge
pipe must terminate at adequate drain.
No valve or other obstruction is to be placed between the relief
valve and the tank. Do not connect tubing directly to discharge
