Water Connections
NOTE: BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE
THE MAIN WATER SUPPLY VALVE.
After shutting the main water supply valve, 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 water heater. The fittings at the cold-water inlet and hot
water outlet have
3/4” NPT tapered male threads. Make the proper
plumbing connections between the water heater and the plumbing system in
the house. Install a shut-off valve in the cold-water supply line.
Inlet and
outlet pipes of the water heater are color-coded. The supply of cold water is
marked with a blue ring. The outlet of warm water is marked with a red ring.
Figure 2: Water Connections
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.
CAUTION
If sweat fittings are to be used, DO NOT apply heat to the nipples
on 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.
IMPORTANT
FAILURE TO INSTALL AND
MAINTAIN A NEW, LISTED 3/4” X 3/4”
TEMPERATURE-PRESSURE RELIEF VALVE WILL RELEASE THE
MANUFACTURER FROM ANY CLAIM WHICH MIGHT RESULT FROM
EXCESSIVE TEMPERATURE AND PRESSURES.
