	drain valve and put the other end
	in a floor drain or outdoors. (See

sure all connections are tight and that
the water flow is directed away from
any person.	FIGURE 5.

5.	Disconnect the vent pipe from the draft hood 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 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.
	See Figure 6. This will avoid cutting off pipes too short.

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
	FIGURE 3.
Figures 2 and 3.

2.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 2

and 4. FIGURE 4.

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.

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.

FIGURE 6.

If you have galvanized pipes 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. See Figure 7. These pieces should be saved since they may be needed when reconnecting the new water heater. 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. 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.
