Relief Valve - GE 30S BLM Serie Manuel D'utilisation

Installation Instructions

RELIEF VALVE

WARNING
Risk of Unit Damage
pressure rating of the relief valve must not
exceed 150 PSI (1.03 MPa), the maximum working
pressure of the water heater as marked on the
rating plate.
A new combination temperature and pressure-relief
valve, complying with the Standard for Relief Valves
and Automatic Gas Shut-Off Devices for Hot Water
Supply Systems, ANSI Z21.22, is supplied and must
remain installed in the opening provided and marked
for this purpose on the water heater. No valve of any
type should be installed between the relief valve and
the tank. Local codes shall govern the installation of
relief valves.
The BTUH rating of the relief valve must not be less
than the input rating of the water heater as indicated
on the rating label located on the front of the heater
(1 watt=3.412 BTUH).
Connect the outlet of the relief valve to a suitable
open drain so that the discharge water cannot contact
live electrical parts or persons and to eliminate
potential water damage.
Piping used should be of a type approved for hot
water distribution. The discharge line must be no
smaller than the outlet of the valve and must pitch
downward from the valve to allow complete drainage
(by gravity) of the relief valve and discharge line. The
end of the discharge line should not be threaded or
concealed and should be protected from freezing.
No valve of any type, restriction or reducer coupling
should be installed in the discharge line.

CAUTION
To reduce the risk of excessive pressures and
temperatures in this water heater, install temperature
and pressure protective equipment required by local
codes and no less than a combination temperature
and pressure relief valve certified by a nationally
recognized testing laboratory that maintains periodic
inspection of production of listed equipment or
materials, as meeting the requirements for Relief
Valves and Automatic Gas Shutoff Devices for Hot
Water Supply Systems, ANSI Z21.22. This valve
must be marked with a maximum set pressure not
to exceed the marked maximum working pressure
of the water heater. Install the valve into an opening
provided and marked for this purpose in the water
heater, and orient it or provide tubing so that any
discharge from the valve exits only within 6 inches
above, or at any distance below, the structural floor,
and does not contact any live electrical part. The
discharge opening must not be blocked or reduced in
size under any circumstances.
TO FILL THE WATER HEATER
WARNING
Risk of Unit Damage -
tank must be full of water before heater is turned
on. The water heater warranty does not cover
damage or failure resulting from operation with
an empty or partially empty tank.
Make certain the drain valve is completely closed.
Open the shut-off valve in the cold water supply line.
Open each hot water faucet slowly to allow the air to
vent from the water heater and piping.
A steady flow of water from the hot water faucet(s)
indicates a full water heater.
Condensation can form on the tank and fittings when
it is first filled with water. Condensation may also
occur with a heavy water draw and very cold inlet
water temperature.
This condition is not unusual and will disappear once
water is heated. If condition persists, examine fittings
for potential leaks and repair, as required.
NOTICE
Do not mis-wire electrical connections. 240VAC or
208VAC must be applied across L1 and L2 wires as
shown in 'Water heater junction box' illustration.
If a 4-conductor wire is supplied to the water heater,
cap the neutral, and connect the remaining wires as
illustrated.
