Removing the Old Water Heater
^^Turn "OFF" the gas supply to the water heater. ©
WARNING
If the main gas line shutoff valve serv­
ing all gas appliances is used, also shut
"OFF" the gas at each appliance. Leave
all gas apfniances shut ’’OFF" until the
water heater installation is completed.
Turn "OFF" the water supply to the
water heater at the water shut off
valve or water meter. Some installa­
tions require that the water be turned
off to the entire house.
Check again to make sure the gas
supply is "OFF" to the water heater.
Then disconnect the gas supply con­
nection 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.
Disconnect the vent pipe from the draft hood
where they connect 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 the 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. This will avoid cutting
off the pipes too short. Additional
cuts can be made later if necessary.
Disconnect the temperature-pres­
sure relief valve drain line. When
the water heater is drained, discon­
nect the hose from the drain valve.
Close the drain valve.The water
heater is now completely discon­
nected and ready to be removed.
ngm b. If you have galvanized pipe to the
water heater, loosen the two galva­
nized pipes with a pipe wrench at
the union in each line. Also dis­
connect the piping remaining to
the water heater. 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 disconnect«! and
ready to be removed.
WARNING
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.
CAUTION
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.
