Water System Piping

Piping Installation

Piping, fittings, and valves should be installed according to the installation drawing (Figure 12). If the indoor installation area is subject to freezing temperatures, the water piping must be protected by insulation.

Water supply pressure should not exceed 80% of the working pressure of the water heater. The working pressure is stated on the water heater’s data plate. If this occurs a pressure limiting valve with a bypass may

7.After piping has been properly connected to the water heater, remove the aerator at the nearest hot water faucet. Open the hot water faucet and allow the tank to completely fill with water. To purge the lines of any excess air, 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.

need to 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 compound and be certain that all fittings are drawn up tight.

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

3.The manufacturer of this water heater recommends installing a tempering valve or an anti-scald device in the domestic hot water line as shown in Figure 13. These valves reduce the point of use temperature of the water by mixing cold and hot water and are readily available for use. Contact a licensed plumber or the local plumbing authority.

4.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” (Page 13).

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 temperature and pressure relief valve in the opening marked “Temperature and Pressure (T & P) Relief Valve” on the water heater. Add a discharge line to the opening of the T & P relief valve. Follow the instructions under Temperature and Pressure Relief Valve" (Page 14).
