Removing the Old Water Heater

FIGURE 2.
1. Turn "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.
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.
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 fl oor
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 fl ow is directed
away from any person, see Figures 2
and 5.
5. Disconnect the vent pipe from the blower assembly 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. Make sure
existing vent complies with maximum and minimum vent lengths on
page 17.
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.
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.
