SYMPTOM
PROBABLE CAUSE
CORRECTIVE ACTION
Thin black coating (soot)
forms on the viewing
glass, logs, or firebox
Improper log or ember
placement
Improper air shutter
setting
Not enough combus-
tion air
See
Firebox Liner Kit and Log Set Installation on Pages 17 and 18
. If there is soot in
one specific location, the glowing embers (rockwool) below this location needs to be
adjusted. This can be done by pulling embers forward slightly. If the flames have soot
tails, the shutter will need to be opened.
If sooting continues open air shutter (see
Air Shutter Adjustment on Page 21
).
Check for debris obstructing air flow in valve compartment under insert or in front of
lower venting.
Humming or whistling
coming from insert.
Normal operating noise
Obstructed orifice
opening
See
Quiet Operation on Page 26
. The noise may be reduced by slightly turning down the
flame. Turning the flame down will reduce the heat output of the appliance.
If noise is excessive or is “whistling” have your gas supplier check the regulator and
orifices and replace if necessary.
A change in flame appear-
ance or burner operation.
A change in gas pres-
sure
Improper ember place-
ment
Have your gas supplier check for correct inlet gas supply pressure (7" W.C. / po. C.E.
[1.74 kPa] natural gas; 11" W.C. / po. C.E. [2.74 kPa] LP gas).
NOTE: NEVER BLOCK OR
OBSTRUCT AIR INTAKE OR OUTLET VENTS.

TROUBLESHOOTING
NOTE: When troubleshooting the gas control system, be sure the external gas shut off valve, located at the gas supply inlet is in
the “ON” position.
IMPORTANT: Call your gas supplier or plumber for additional help with any gas control problem. Valve system troubleshooting
should only be accomplished by a qualified service technician.
