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 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.
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.
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.
