Water Connections - Bradford White THROUGH-THE-WALL GAS WATER HEATER Install And Operation Instructions

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 3/4" 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 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 AND PRESSURE RELIEF VALVE WILL RELEASE THE
MANUFACTURER FROM ANY CLAIM THAT MIGHT RESULT FROM
EXCESSIVE TEMPERATURE AND PRESSURES.
If this water heater is installed in a closed water supply system, such as one
having a back-flow preventer in the cold water supply, provisions must 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.
