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.
('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.
