1. Turn "OFF" the gas supply to the water heater.
If the main gas line shutoff valve serving all gas
appliances is used, also shut "OFF" the gas
at each appliance. Leave all gas appliances
shut "OFF" until the water heater installation is
completed. See Figures 5 and 6.

Check again to make sure the gas supply is
"OFF" to the water heater. Then disconnect
the gas supply connection from the gas control
valve.
Attach a hose to the water heater drain valve
and put the other end in a floor drain or
outdoors. (See Figures 5 and 8.) Open the water
heater drain valve. The water passing out of
the drain valve may be extremely hot. To avoid
being scalded, make sure all connections are
tight and that the water flow is directed away
from any person.

2. Open a nearby hot water faucet until the water
is no longer hot. When the water has cooled,
turn "OFF" the water supply to the water heater
at the water shut off valve or water meter. Some
installations require that the water be turned off
to the entire house. See Figures 5 and 7.

Disconnect the vent pipe from the draft hood or
blower where it connects to the water heater. In
most installations the vent pipe can be lifted off
after any screw or other attached devices are
removed. Dispose of the draft hood. The new
water heater has a blower coupling which must
be used for proper operation.
If you have copper piping to the water heater,
the two copper water pipes can be cut with a
hacksaw or tubing cutter approximately four
inches away from where they connect to the
water heater. See Figure 9. This will avoid
cutting off pipes too short. Additional cuts can
be made later if necessary. Disconnect the
temperature-pressure relief valve discharge
pipe. When the water heater is drained,
disconnect the hose from the drain valve.
Close the drain valve. The water heater is
now completely disconnected and ready to be
removed.
