Water System Piping

Piping, fittings, and valves should be installed according to the installation drawing (Figure 4). If the indoor installation area is subject to freezing temperatures, the water piping must be properly insulated.

Water supply pressure should be 50-60 PSIG and not exceed the maximum 80 PSIG. If the supply line pressure exceeds 80 PSIG, a pressure reducing valve (PRV) with a bypass should be installed in the cold water supply line. This should be placed on the supply to the entire house in order to maintain equal hot and cold water pressures.

IMPORTANT:

•Heat must not be applied to the water fittings on the heater as they may contain nonmetallic parts. If solder connections are used, solder the pipe to the adapter before attaching the adapter to the hot and cold water fittings.

•Always use a good grade of joint compound and be certain that all fittings are tight.

IMPORTANT: DO NOT over apply joint compound.

Piping Installation

1.Install the water piping and fittings as shown in Figure 4. Connect the cold water supply (3/4” NPT) to the fitting marked “Cold”. Connect the hot water supply (3/4” NPT) to the fitting marked “Hot”.

2.The installation of unions in both the hot and cold water supply lines are recommended for ease of removing the water heater for service or replacement.

3.Some local codes may require, and the manufacturer of this water heater recommends, installing a mixing valve or an anti-scald device in the domestic hot water line as shown in Figure 4. These valves reduce the point-of-use temperature of the hot water by mixing cold and hot water and are readily available. Contact a licensed plumber or the local plumbing authority for more information.

4.Some local codes may require, and the manufacturer of this water heater recommends, installing a pressure reducing valve (PRV) in the cold water inlet line where it enters the residence as shown in Figure 4.

5.If installing the water heater in a closed water system, install an expansion tank in the cold water line as specified under “Closed System/Thermal Expansion.”

6.Install a shut off valve in the cold water inlet line. It should be located close to the water heater and be easily accessible. Know the location of this valve and how to shut off the water to the heater.

7.Install a discharge line from the temperature and pressure relief valve in the opening marked “T & P RELIEF VALVE”. See Figure 5 and the “Temperature and Pressure Relief Valve” section.)

8.After piping has been properly connected to the water heater, open the nearest hot water faucet. Then open the cold water shut off valve and allow the tank to completely fill with water. To purge the lines of any excess air and sediment, keep the hot water faucet open for 3 minutes after a constant flow of water is obtained. Close the faucet and check all connections for leaks.
