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
3 and 4.
2. Turn "OFF" the water supply to the
water heater at the water shut off
valve or water meter.
installations require that the water
be turned off to the entire house, see
Figures 3 and 5.
3. 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.

4. Attach a hose to the water heater drain
valve and put the other end in a floor
drain or outdoors. Open the water
heater drain valve. Open a nearby hot
water faucet which will relieve
pressure in the water heater and speed
draining. 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,
see Figures 3 and 6.
5. Disconnect the vent pipe from the draft hood where they connect 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 the draft hood which must
be used for proper operation.
6. If you have copper piping to the water heater, the two copper water
pipes can be cut with a hacksaw approximately four inches away
from where they connect to the water heater. This will avoid cutting
off pipes too short. Additional cuts can be made later if necessary.
Disconnect the temperature-pressure relief valve drain line. 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, see Figure 7.
If you have galvanized pipe to the water heater, loosen the two
galvanized pipes with a pipe wrench at the union in each line. Also
disconnect the piping remaining to the water heater. These pieces
should be saved since they may be needed when reconnecting the
new water heater. Disconnect the temperate-pressure relief valve
drain line. 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. Mineral buildup or
sediment may have accumulated in the old water heater. This causes
the water heater to be much heavier than normal and this residue, if
spilled out, could cause staining, see Figure 8.
