Water System Piping

Piping Installation

Piping, fittings, and valves should be installed according to the installation drawing (Figure 3). If the indoor in- stallation area is subject to freezing temperatures, the water piping must be protected by insulation.

Water supply pressure should be around 50 to 60 psi and should not exceed 80 psi. If this occurs, a pressure reducing valve should be installed in the cold water inlet line. This should be placed on the supply to the entire house in order to maintain equal hot and cold water pressures.

IMPORTANT: Heat cannot 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.

IMPORTANT: Always use a good grade of joint com- pound and be certain that all fittings are drawn up tight.

1.Install the water piping and fitting as shown in Figure 3. 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”.

IMPORTANT: Some models may contain energy saving heat traps to prevent the circulation of hot water within the pipes. Do not remove these inserts.

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

3.Some local codes may require, and the manufac- turer of this water heater recommends, installing a mixing valve 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.

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

5.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.

6.Install a discharge line from the temperature and pressure relief valve in the opening marked “T & P RELIEF VALVE”. Install as specified under “Temperature and Pressure Relief Valve”.

7.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.
