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 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 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.

WARNING

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, WHICH MIGHT RESULT FROM

EXCESSIVE TEMPERATURE AND PRESSURES.

CAUTION

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.
