Installing the NEW Water Heater

SECTION A - GALVANIZED PIPING

(See Figure 15)

1.Position the water heater so that the existing piping will require the shortest distance between connections. Make sure that you are able to reach the drain valve and all connections when the water heater is in place. This will make it easy to service the water heater. The water heater must be level before you begin the piping.

If a water heater is installed in a closed water supply system, such as one having a back-flow preventer, check valve, water meter with check valve, etc. . . in the cold water supply, means shall be provided to control thermal expansion. Contact a qualified installer or service agency on how to control this situation.

2.Place the draft hood in the receiving holes where it connects to the water heater. The legs should snap in to give a tight fit.

Secure the legs of the draft hood with the supplied draft hood brackets, see Figures 16 and 16A.

3.Place the vent pipe over the draft hood. With the vent pipe in position, drill a small hole through both the vent pipe and draft hood. Secure them together with a sheet metal screw.

4.Wrap the 1” NPT threaded nipples (75 gallon models) or 1.25” NPT threaded nipples (100 gallon models) with teflon tape or pipe joint compound, see Figure 17. Connect the existing piping to the water heater.

5.See the Temperature-Pressure Relief Valve section for instructions on installing the discharge pipe.

6.Connect the flexible gas connector to the incoming gas line using the end with the 1/2” female fitting, a 1/2” threaded nipple is available if needed. The 1/2” male fitting on the other end is to be connected to the gas thermostat. Make sure that the gas type you have is the same as the gas type indicated on the rating plate. Make sure that all connections are tight. All threaded fittings must have teflon tape or pipe dope (which is resistant to the action of liquefied petroleum (L.P. Gas) applied, see Figure 15.

7.With the thermostat knob in the “OFF” position, turn the gas on. Check for leaks with a soapy solution. If leaks are found, turn the gas off immediately and correct. Do not test for gas leaks with a match or flame. Read Lighting instructions on page 20 for natural gas models and page 21 for propane gas models. Do not light the water heater until it is completely filled with water.
