Unit does not ignite
when water goes
through the unit.
•
Is the flow rate over 0.5 GPM (1.9 L/min)? (p. 50)
•
Is the filter on cold water inlet and return connection clean? (p. 63)
•
Check for reverse connection and cross connection.
•
If you use the remote controller and/or built-in controller, is the
power button turned on?
•
Check if the inlet temperature is too high.
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.
