ELECTRICAL POWER BEFORE
SERVICING THE STOVE!
CAUTION: Label all wires prior to disconnection when servic-
ing controls. Wiring errors can cause improper and dangerous
operation. Verify proper operation after servicing. This stove
and its venting system should be inspected before use and
at least annually by a qualifi ed service person. The fi replace
area must be kept clear and free of combustible materials,
gasoline or other fl ammable vapours and liquids. The fl ow of
combustion and ventilation air must not be obstructed.
1. In order to properly clean the burner and pilot assembly,
remove the logs exposing 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 fl ames are large enough to
engulf the thermocouple and the thermopile on one leg and
reaches toward the burner on the other leg.
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 5-10 second total light-up period is satisfactory. If ignition
takes longer, consult your Napoleon dealer/distributor.
7. Check that the door gasketing is not broken or missing.
MAINTENANCE
Remove the 2 screws securing the burner. Natural gas models
have air shutters set to 0.25" open (1/4"). Propane models
have air shutters set to 0.438" open (7/16").
After making adjustments replace the burner ensuring that the
venturi tube fi ts over the orifi ce and replace the screws. Closing the air shutter will cause a more yellow fl ame, but
can lead to carboning. The fl ame may not appear yellow
immediately; allow 15 to 30 minutes for the fi nal fl ame
colour to be established.
