Corrective Action
Check the LP (propane) tank. Refill the
fuel tank.
Check for gas leaks.
The horizontal flue cap should slope
down only enough to prevent any water
from entering the unit. The maximum
downward slope is 0.6 cm.
Tighten the corner.
Replace if necessary.
Check for proper installation and
freedom from debris or blockage.
Adjust the log set so that the flame
does not excessively impinge on it.
Adjust the air shutter at the base of the
burner.
Inspect the opening at the base of the
burner. NO MATERIAL SHOULD BE
PLACED IN THIS OPENING.
Ensure that the flue cap is installed
properly and free of debris. Ensure that
the flue system joints are tight and
have no leaks.
Ensure that no debris has been placed
in the area at the base of, or in the area
of, the air holes in the center of the
base pan beneath the burner.
Ensure that the glass is tightened
properly on the unit, particularly on top
corners.
