Locate pilot adjustment screw on gas control
valve. Flame is decreased by turning adjustment
screw clockwise.
Pilot won't
ignite
Disconnect remote wires and try to light pilot. If
pilot now works, remote connections are faulty.
Check wiring diagram
Main burner
will not light
1. Check wiring
2. Check wall switch for proper connection
PROBLEM

are installed in the remote control and backup
battery pack (if available).
3. Check the 3.15A fuse in the control box and
replace if necessary
Pilot Igniter
sparking, but
Pilot burner
will not light
1. Verify the Inlet and Manifold Gas Pressure are
within acceptable limits
2. Check all connections to gas valve
3. Check connection to stepper motor (if
available)
Pilot lights , but
Main burner
will not Light
1. Check and verify all wiring connections as per
the wiring diagram.
2 . Verify the inlet and Manifold Pressure are

Annual inspection list for determining safe operation of
a direct vent gas fireplace
1)
Inspect and operate the pressure relief mechanism to verify relief mechanisms are free
from obstruction to operate.
2)
Clean glass window with a suitable fireplace glass cleaner. Abrasive cleaners must not
be used. Be careful not to scratch the glass when cleaning.
3)
Inspect the operation of the flame safety system Pilot or Flame rectification device.
4)
Inspect and ensure the lighting of the main burner occurs within 4 seconds of the
main gas valve opening. Visual inspection should match that outlined in the appliance
instruction manual. Inspect primary air openings for blockage.
5)
Inspect condition of vent and vent terminal for sooting or obstruction and correct if
present.
6)
Vacuum and clean any debris in the firebox that is not supposed to be there.
7)
Test and measure the flame failure response time of the flame safety system. It must
de-energize the safety shutoff in no more than 30 seconds.
8)
Check all accessible gas-carrying tubes, connections, pipes and other components for
leaks.
