Water Connections - Bradford White RE380T6 Manual

Water Connections

NOTE: BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE THE
MAIN WATER SUPPLY VALVE.
After shutting the main w ater supply valve, open a faucet to relieve the
w ater line pressure to prevent any w ater from leaking out of the pipes
w hile making the w ater connections to the w ater heater. After the
pressure has been relieved, close the faucet. The COLD w ater inlet and
HOT w ater outlet are identified on top of the w ater heater. The fittings
at the cold w ater inlet and hot w ater outlet are dielectric w aterw ay
fittings w ith 3/4'' NPT tapered male threads. Make the proper plumbing
connections betw een the w ater heater and the plumbing system in the
house. Install a shut-off valve in the cold w ater supply line.
If sweat fittings are to be used, 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 3/4'' X 3/4''
TEMPERATURE-PRESSURE RELIEF VALVE WILL RELEASE THE
MANUFACTURER FROM ANY CLAIM WHICH MIGHT RESULT FROM
EXCESSIVE TEMPERATURE AND PRESSURES.
If this w ater heater is installed in a closed w ater supply system, such as
the one having a back-flow preventer in the cold w ater supply,
provisions shall be made to control thermal expansion. DO NOT operate
this w ater heater in a closed system w ithout provisions for controlling
thermal expansion. Your w ater supplier or local plumbing inspector
should be contacted on how to control this situation.
After installation of the w ater lines, open the main w ater supply valve
and fill the w ater heater. While the w ater heater is filling, open several
hot w ater faucets to allow air to escape from the w ater system. When
a steady stream of w ater flow s through the faucets, close them and
check all w ater connections for possible leaks. NEVER OPERATE THE
WATER HEATER WITHOUT FIRST BEING CERTAIN IT IS FILLED WITH
WATER.
