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.
