PROBLEM SOLUTIONS
WATER HEATER
Unit does not ignite
when water goes
through the unit.
Is the flow rate over 0.5 GPM (1.9 L/min)? (p. 41)
Check the filter on the cold water inlet. (p. 46)
Check for reverse connection and cross connection.
If you use the remote controller, is the power button turned on?
Check if the inlet water temperature is too high. If it is too close to
the set temperature, the water heater won't work.
Is the gas supply turned on?
Is power available to the unit? If so, is the power button on the
controller or inside the water heater turned on?
The fan motor is
still spinning after
operation has stopped.
This is normal. After operation has stopped, the fan motor keeps
running from 15 to 70 seconds in order to re-ignite quickly, as well
as purge all the exhaust gas out of the flue.
