34 Ortal Power Vent System Manual
Issue: The pilot is on, but the burner and Fan Exhaust are not
operating properly.
Solution: The pressure switch does not recognize pressure in the
vent, and causes the gas solenoid to be closed.
Consider the following:
i. Refer to the LED table. If a light that should be on does
not display, failure is indicated.
ii. Confirm that the control box is in a level position with the
directional arrow up.
iii. Make sure the pressure switch is correctly installed and
connected to the pressure switch tube.
iv. Confirm that all terminations in the control box are
properly connected.
v. Look for obstruction.
vi. Check exhaust pipe connection.
vii. Check the gas tube between the GV60 valve and the
burner port.
viii. The inlet pressure is too low, too high, or not in the
required range. Check with gas provider.
Issue: The pilot is on, the fan is on, but the burner does not operate.
Solution: A possible gas solenoid failure. The gas solenoid is not
open, OR a wire (see termination #2) from control to gas
solenoid is not connected, OR there is no proven draft.
Issue: The pilot is on, the burner is on, but the fan does not operate.
Solution: Definite failure with the gas solenoid. Shut down the
system due to high CO levels in the fireplace. If the
fireplace does not immediately shut down, manually turn
off the fireplace.
Issue: The burner is on, but disengages without the use of the
remote control (it goes off by itself).
