Relief Valve - Bradford White RE2H50S-1NCWT Serie Guide Rapide

CONDENSATION DRAIN CONNECTION
This unit has a condensate drain; therefore a floor or other drain no
higher than 36" (91.4cm) above the floor must be available in close
proximity to the water heater to allow for the shortest possible drain
line with minimal turns to be installed. Drain must meet state and
local codes. It is important to install a 3/4" FNPT fitting suitable for
either rigid or flexible drain line to the primary drain port coming off
the side of the unit. Diameter reductions from a 3/4" drain line are
not recommended.
Ensure that the rigid or flexible drain line maintains a downward
slope to allow for proper gravity drainage of condensate to the drain
and to allow for proper function of the condensate drain blockage
sensor (see page 12). If no drain is available, then a common
condensate pump with a capacity no less than 1 gallon (3.8L)/day
must be purchased and installed. It is important to route the flexible
or rigid drain line so that the discharge water cannot contact live
electrical parts or cause water damage .

RELIEF VALVE

WARNING:
pressure rating of the relief valve must not exceed 150 PSI (1.03
kPa), the maximum working pressure of the water heater as
marked on the rating plate.
A new combination temperature/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 opening provided and marked for the 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 relief valve outlet to a suitable open drain so 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.

Risk of Unit Damage -
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:
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.
Fitting
Make certain the drain valve is completely closed.
Open the shut-off valve in the cold water supply line.
Drain
Open each hot water faucet slowly to allow the air to vent from the
Line
water heater and piping.
A steady flow of water from the hot water faucet(s) indicates a full water
heater.
"F11" fault code during installation: If the unit is powered on without a
The
full tank, the error code "F11" will show in the display. Turn off the power,
fill the tank with water (see above), then turn the power back on.
NOTE: The DRY TANK DETECTION feature on tank is for the aid of installer
and should NOT be used as the primary control to prevent operation with
an empty or partially filled tank. Power should NEVER be applied to the
water heater until installer has verified tank is filled and all air has been
purged from system.
NOTICE:
Do not mis-wire electrical connections. 240V AC or 208AC must be
applied across L1 and L2 wires as shown in 'Water heater junction
box' illustration. Failure to do so will VOID the warranty, and can result
in 120V applied to water heater, which may damage the compressor
or other electrical components.
If 4-conductor wire is supplied to the water heater, cap the neutral,
and connect the remaining wires as illustrated.
NOTE REGARDING UTILITY POWER-MANAGEMENT DEVICES
(Sometimes called Peak Load Reduction Switches):
Some power-management switching devices or even some basic
timer switches exist that REDUCE voltage from 240V to 120V during
high-electricity-demand periods. These devices must be removed
from the circuit providing power to the water heater because of the
potential unit damage noted above.
However, switching devices which cut power from 240V to 0V on a
periodic basis are acceptable.
"bAd linE" fault code during installation: If "bAd linE" is shown on
the display, the unit is not receiving the correct voltage as a result of
incorrect wiring. To correct this fault, turn the power off to the unit,
correct the wiring issue, then turn the power back on.
