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

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.
