NON-MALFUNCTIONING SYMPTOMS & SOLUTIONS
White smoke coming from flue
Failing to light upon first use
after installation or first use
after sitting dormant
Fan still spinning after
unit shuts down
Unit will not fire
with low flow
Water coming out of
pressure relief valve
White smoke can be caused from the hot air exiting the exhaust
into cooler temperatures outside. This is normal.
There may be air in the gas line. Open and close the hot water
tap (allow the unit to attempt to fire before closing the tap) until
successful ignition occurs.
The fan will continue to run after the unit shuts down for a
short time to exhaust all air out of the unit.
The flow of water must be at or above 0.6 gallons per minute for
the unit to recognize water flow and kick on.
Open the pressure relief valve to relive any built up pressure
inside the heat exchanger.
