ADJUSTMENT, CLEANING and MAINTENANCE
Venturi Adjustment
Natural gas models have a closed shutter. Opening the air shutter will
cause a more blue flame, but can cause flame lifting from the burner
ports. Propane gas models have an air shutter set at 3/16" (.188 mm)
open. The same conditions as above apply for propane gas.
Air shutter adjustment must only be
done by a qualified gas installer.
Turn off gas before servicing fireplace. It
is recommended that a qualified service
technician perform these check-ups at
the beginning of each heating season.
Air flowing through the appliance will cause dust and lint to collect on the grate, burner and
logs. Excessive build-up of dust and lint can cause the pilot and burner to operate improperly
and produce hazardous levels of carbon monoxide, a poisonous gas. The appliance may pro-
duce carbon (soot) during operation. This carbon (soot) may collect on some logs, some areas
of the grate and on the fireplace and vent. Slight carbon build-up is acceptable.
The following is a recommended monthly maintenance program:
1. Turn the gas OFF at the line shut-off valve and allow the appliance to cool.
2. Blow or vacuum all dust and lint out of the appliance, paying particular attention to the pilot,
air shutter end of the burner, air passage into and through the appliance and control.
3. Vacuum or brush away all dust, carbon or lint on the logs and grate.
4. Turn the gas ON at the line shut-off valve and light the appliance according to the lighting
instructions.
5. Check all piping, pilot tubing and manifold connections for leaks with a soap and water or
liquid leak detecting solution. If any leaks are observed, turn the gas OFF immediately and
make the necessary repairs.
6. Light the pilot and visually inspect the flame appearance. NOTE: Any maintenance of the
appliance that requires disconnection of the appliance from the gas line or removal of the
control, burner or pilot should only be performed by a qualified person.
