• OPEN a nearby hot water faucet and leave open to allow for
draining.
• Connect a hose to the drain valve and terminate to an
adequate drain.
• OPEN the water heater drain valve to allow for tank draining.
NOTE: If the water heater is going to be shut down and
drained for an extended period, the drain valve should be
left open with hose connected allowing water to terminate
to an adequate drain.
• CLOSE the drain valve.
• Follow instructions in the Filling The Water heater section.

TROUBLESHOOTING
Start Up Conditions
Draft Hood Operation
Check draft hood operation by performing a worst case
depressurization of the building. With all doors and windows
closed, and with all air handling equipment and exhaust fans
operating, such as furnaces, clothes dryers, range hoods and
bathroom fans, a match flame should still be drawn into the
draft hood of the water heater with its burner firing. If the flame
is not drawn toward the draft hood, shut off the water heater
and make necessary air supply changes to correct.
Condensation
Whenever the water heater is filled with cold water, some
condensate will form while the burner is on. A water heater
may appear to be leaking when in fact the water is condensation.
This usually happens when:
• A new water heater is filled with cold water for the first time.
• Burning gas produces water vapor In water heaters,
particularly high efficiency models where flue temperatures
are lower.
• Large amounts of hot water are used in a short time and
the refill water in the tank is very cold.
Moisture from the products of combustion condense on the
cooler tank surfaces and form drops of water which may fall
onto the burner or other hot surfaces to produce a “sizzling” or
“frying” noise.
Excessive condensation can cause pilot outage due to water
running down the flue tube onto the main burner and putting
out the pilot.
Because of the suddenness and amount of water,
condensation water may be diagnosed as a “tank leak”. After
the water in the tank warms up (about 1-2 hours), the condition
should disappear.
Do not assume the water heater is leaking until there has
been enough time for the water in the tank to warm up.
An undersized water heater will cause more condensation.
The water heater must be sized properly to meet the family’s
demands for hot water including dishwashers, washing
machines and shower heads.
