Natural gas models have air shutters set at 1/8 (.125) inch open. Propane gas
models have air shutters set at 1/4 (.250) inch open. Closing the air shutter will
cause a more yellow flame, but can lead to carboning. Opening the air shutter
will cause a more blue flame, but can cause flame lifting from the burner ports.
The flame may not appear yellow immediately; allow 15 to 30 minutes for the
final flame colour to be established.

AIR SHUTTER ADJUSTMENT MUST ONLY BE DONE BY A QUALIFIED GAS INSTALLER!

TURN OFF THE GAS AND ELECTRICAL POWER BEFORE SERVICING THE FIREPLACE.
CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and danger-
ous operation. Verify proper operation after servicing. This fireplace and its venting system should be inspected before
use and at least annually by a qualified service person. The fireplace area must be kept clear and free of combustible
materials, gasoline or other flammable vapours and liquids. The flow of combustion and ventilation air must not be
obstructed.
1. In order to properly clean the burner and pilot assembly, remove the logs to expose both assemblies.
2. Keep the control compartment, logs, burner, air shutter opening and the area surrounding the logs clean by vacuum-
ing or brushing, at least once a year .
3. Check to see that all burner ports are burning. Clean out any of the ports which may not be burning or are not burning
properly.
4. Check to see that the pilot flame is large enough to engulf the thermocouple and thermopile and reaches toward the
burner with the third jet.
5. Replace the cleaned logs.
6. Check to see that the main burner ignites completely on all openings when the gas knob for the burner is turned on.
A 5 to 10 second total light-up period is satisfactory. If ignition takes longer, consult your Napoleon dealer / distributor.
7. Check that the gasketing on the sides, top and bottom of the door is not broken or missing. Replace if necessary.
