FIGURE 2.
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.
FIGURE 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.
4.
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 any person, see
Figures 2 and 5.
FIGURE 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.
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.
• Burn hazard
• Hotwater discharge.
° Keep hands clear of drain valve
discharge.
