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.	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	FIGURE 4.
	entire house. See Figures 2

and 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.

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. 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.
