fittings onto the nipples, hand tight. Then measure and cut the copper tubing. Please note that special adapters may be needed to match existing piping.
Remove the fittings, then go to the next step, see Figure 23.
Flux the ends of the length of pipe cut for the T & P line and the inside of the 3/4” male threaded to sweat connector. Then solder this assembly together. Do not screw the connector into the

8.The female threaded to sweat connectors and two pieces of copper pipe to connect the water heater to the house plumbing should be cleaned, fluxed and assembled. Do not screw the connectors into the nipples in the tank before soldering.
Solder pipe/connector assembly as shown. When solder flows into and completely around the joint, you should remove the solder and the heat immediately, see Figure 24.

14.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 type gas 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).
15.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 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, see Figure 26.
