Installation / Operation Instruction Manual

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 in order to prevent 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 line connects to the inlet

nipple at the base of the water heater. The hot water outlet line connects to

the nipple on top of the water heater. The fittings at the cold water inlet and

hot water outlet are dielectric waterway fittings with tapered male threads.

Make the proper plumbing connections between the water heater and the

plumbing system in the structure. Install a manual shut-off valve in the cold

water supply line.

This water heater may be provided with an optional pressure and

temperature gauge. See Figure 1 for proper installation.

If this water heater is installed in a closed water supply system, such as 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 a provision for controlling thermal expansion. Contact

your water supplier or local plumbing inspector regarding how thermal

expansion can be controlled.

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 the faucets and inspect all water

connections for possible leaks. NEVER OPERATE THE WATER HEATER

WITHOUT FIRST BEING CERTAIN IT IS COMPLETELY FILLED WITH

WATER.

CAUTION

If sweat fittings are to be used, 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.

IMPORTANT

FAILURE TO INSTALL AND MAINTAIN A NEW, LISTED

TEMPERATURE-PRESSURE RELIEF VALVE WILL RELEASE THE

MANUFACTURER FROM ANY CLAIM WHICH MIGHT RESULT FROM

EXCESSIVE TEMPERATURE AND PRESSURES.
