L. Inspect the Venting System
The fireplace venting system is designed and constructed to
develop a positive flow adequate to remove flue gases to the
outside atmosphere. See fireplace installation instructions.
Possible cures if spilling occurs:
• The damper needs to be opened further.
• The fireplace opening needs to be reduced by adding a
drop panel across the top under the lintel.
• The air supply from outdoors needs to be increased. Open
the outside air kit if the appliance is so equipped, or crack
open a door or window.
• If necessary, seek expert advice. Do not operate this
appliance.
Cleaning
• Periodic examination and cleaning of the venting system
of the fireplace should be done before initial use and at
least annually by a qualified agency.
A spillage test must be made before the installed
appliance is left with the consumer.
• Close all doors and windows in the home.
• Light the log set (see Lighting Instructions).
• After three minutes, test with a smoke match, smoke
candle, stick incense or cigarette 1 in. below the top of
the opening (lintel) moving across the full width. If spillage
(smoke down into the room) occurs, it will most likely be
near the top, outside corners.
Before cleaning the appliance, be sure it is turned
completely off. The pilot should also be turned off. The
unit must be completely cooled.
CAUTION
• Logs can get very hot. Handle only when they are
cool.
CAUTION
After burning, the logs become fragile. Take care in
handling.

annual examination and cleaning of the venting system by a
qualified person is also recommended.
N. Safety Valve Pilot Flame Adjustment In-
structions
The pilot flame adjustment screw is located on the front
side of the pilot gas tubing port. Using a small straight blade
screwdriver, turn the screw clockwise
to adjust the pilot
flame down and counterclockwise
to adjust the flame
up. This screw is sensitive; therefore it will not take much
adjustment to accomplish this flame adjustment.

Your logs require little care. Keep the burner assembly, logs
and burner area surrounding the logs clean by brushing with
a dry paint brush at least twice a year.
• Always turn off the gas to the pilot before cleaning.
For relighting, refer to Section P Thru R. Lighting
Instructions.
• Always keep the appliance clean and free from combustible
materials, gasoline and other flammable vapors and
liquids.
• Never obstruct the flow of combustion and ventilation air.
Keep the front of the appliance clear of all obstacles and
materials.
• Leave clearance of at least 36 in. from the front of the
fireplace.
