•Always use a proper grade of joint compound and be cer-

tain that all fittings are drawn up tight.

1.Install the water piping and fittings as shown in Figures 7 or 8. Connect the cold water supply to the fitting (3/4” NPT) marked “COLD” (or “C”). Connect the hot water supply to the fitting (3/4” NPT) marked “HOT” (or “H”).

2.The installation of unions in both the hot and cold water supply lines is recommended.

3.The manufacturer of this water heater recommends installing a tempering valve in the domestic hot water line. These valves reduce the point-of-use water tem- perature by mixing cold and hot water. 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 spec- ified 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 eas- ily accessible. The owner/operator must be shown the location of this valve and be given instructions on how to use it to shut off the water to the heater.

NOTE: Rear and Combination flue heaters are equipped with a combination cold water inlet/drain valve.

Filling the Water Heater

Do not insert the power cord into the electrical receptacle until all the following steps have been completed.

1.Make sure the drain valve is closed.

2.Open all hot water faucets served by the system to allow air to escape from the tank.

3.Open the cold water inlet valve.

NOTE: When filling, avoid water leakage. Do not allow the insulation of the water heater to get wet as water can reduce the effectiveness of the insulation.

4.When an uninterrupted stream of water, without appar- ent air bubbles, flows from the open hot water faucets, the tank is full.

5.Close the hot water faucets and check the system for leaks. Repair as required and retest.

6.Connect a hose to the drain valve and route to a suit- able drain.

7.Open the drain valve and let water run to flush out any foreign matter that may have entered the system. Continue flushing until clean water flows.

8.Close the drain valve, disconnect the hose, ensure the drain valve does not drip and re-fill the tank.

Please note the following:

DO NOT install this water heater with iron piping. The sys- tem should be installed only with piping that is suitable for potable (drinkable) water such as copper, CPVC or poly- butylene. DO NOT use PVC water piping.
