SECTION VI: 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 front of the water heater. Make sure the diptube is
in place before making the cold water connection. 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.
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.

If sweat fittings are to be used,
DO NOT
apply heat to the nipples on the side of the water heater. Sweat the tubing to
the adapter before fitting the adapter to the water heater connections. It is imperative that heat is not applied to the
nipples containing a plastic liner.
CAUTION
FAILURE TO INSTALL AND MAINTAIN A NEW, LISTED TEMPERATURE AND PRESSURE RELIEF VALVE WILL
RELEASE THE MANUFACTURER FROM ANY CLAIM WHICH MIGHT RESULT FROM EXCESSIVE
TEMPERATURE AND PRESSURES
.
WARNING
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 must be made to control thermal expansion.
DO NOT
operate this water heater in a closed
system without provisions for controlling thermal expansion. Warranties do not cover damages from thermal expansions
such as pressure bulges and/or deformities. Your water supplier or local plumbing inspector should be contacted on
how to control this situation.
