QCheck again to make sure the gas supply is "OFF" to the water heater. Then dis-
connect the gas supply connection from the gas control valve.
QAttach 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.
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.

ed when reconnecting the new water heater. Disconnect the
completely disconnected and ready to be removed.

The water passing out of the drain valve may be extremely I hot. To avoid being scalded, make sure all connections are I tight and that the water flow is directed away from any I
person. |
ACAUTION
Mineral buildup or sediment may have accumulated in the old water beater. This causes the water heater to be much heavier than normal and this residue, if spilled out, could cause staining.
