Water Connections - Bradford White URG250H6N-475-264 Manual

WATER CONNECTIONS

Note: BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE THE
MAIN WATER SUPPLY VALVE.
After shutting off the main water supply, open a faucet to relieve the water line
pressure to prevent any water from leaking out of the pipes while making the
water connections to the water heater. After the pressure has been relieved,
close the faucet. The cold-water inlet and hot-water outlet are identified on the
top of the water heater. The fittings at the cold-water inlet and hot-water outlet
are dielectric waterway fittings with ¾ inch NPT male thread. Make the proper
plumbing connections between the water heater and the plumbing system to
the house. Install a shut-off valve in the cold-water supply line.
If sweat fittings are to be use, DO NOT apply heat to the nipples on top of
the water heater. Sweat the tubing to the adapter before fitting the
adapter to the water connections. It is imperative that heat is not applied
to the nipples containing a plastic liner.
FAILURE TO INSTALL AND MAINTAIN A NEW, LISTED ¾ INCH X ¾
INCH TEMPERATURE AND PRESSURE RELIEF VALVE WILL
RELEASE THE MANUFACTURER FROM ANY CLAIM, WHICH MIGHT
RESULT FROM EXCESSIVE TEMPERATURE AND PRESSURES.
If this water heater is installed in a closed water supply system, such as the
one having a back-flow preventer in the cold-water supply, provisions shall be
made to control thermal expansion. DO NOT operate this water heater in a
closed system without provisions for controlling thermal expansion. Your
water supplier or local plumbing inspector should be contacted on how to
control this situation
After installation of the water lines, open the main water supply valve and fill
the water heater. While the water heater is filling, open several hot water
faucets to allow air to escape from the water system. When a steady stream
of water flows through the faucets, close them and check all water connections
for possible leaks. NEVER OPERATE THE WATER HEATER WITHOUT
FIRST BEING CERTAIN IT IS FILLED WITH WATER.
