shown. Clean the inside of each sweat fitting with the wire
brush as shown. Make sure you do not touch the cleaned
areas, see Figure 22.
FIGURE 22.
7. Using the diagram map out the installation. Screw
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.
FIGURE 23.
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.

9. Using your pipe wrench, secure the pipe/connector
assemblies onto the nipples.
10. Flux the ends of piping and inside the couplings.
11. Put the pipes and coupling together and solder as show
Solder the top first, and then quickly solder the bottom.
12. See the Temperature-Pressure Relief Valve section and
the text in Steps 12 and 13 for instructions on installing
the discharge piping.
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 Temperature-Pressure Relief Valve
before the assembly is soldered together, see Figure 25.
13. Using your pipe wrench, screw the assembly into the
Temperature-Pressure Relief valve, see Figure 25.

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.

16. After checking that all connections are tight and the drain
valve near the bottom of the water heater is closed, go to
“Filling the Water Heater”.
