7. Close drain valve; remove hose and
turn water back on. Allow unit to
refill. Leave T&P open until water
comes out the drain line. Open a hot
water faucet and allow it to run for
about 30 seconds. This will evacuate
all of the air from the tank. Check for
water leaks and tighten the gas valve
if necessary.
8. Reconnect the pilot supply tube
(7/16") and the main gas supply tube
(3/4"), and attach the orange ignitor
wire to the gas control valve.
9. Reinstall the gas line to the valve.
You will need pipe dope suitable for
gas supply (or other sealer required by
local code) on the black pipe
connection to the gas valve.
10. Turn on the manual gas shut-off valve
near the water heater. Use a soapy
water solution to test for leaks at all
connections and fittings to the gas
valve. Bubbles indicate a gas leak that
must be corrected.
11. Turn gas valve to ON and turn the
thermostat up to demand heat. After
running main burner for 3 minutes,
recheck for gas leaks at the gas valve
connections. Don't forget the pilot
and main burner supply tube
connections at the bottom of the
valve.
12. Set red temperature dial on thermostat
to a safe position not to exceed 120
degrees. Replace jacket door.
