Removing the Old Water Heater

F_URE2.

QTurn "OFF" the gas supply to the water heater,

If the main gas line shut-off 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 2 and 3. FIGURE3.

(_ 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.

(_) 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. 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	FK_URE5.
any person, see Figures 2 and 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.

QIf 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.

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.
