MAINTENANCE

1. Keep the control compartment, burner, and air shutter opening
clean by vacuuming or brushing, at least once a year.
2. Check to see that the main burner ignites when the switch
for the burner is turned on. A 5 second light-up period is satis-
factory. If ignition takes longer, consult your Napoleon® dealer
/ distributor.
3. Check that the gasketing on the sides, top and bottom of the
door is not broken or missing. Replace if necessary.
ADJUSTMENTS
Closing the air shutter will cause a more yellow fl ame, but can
lead to carboning. Opening the air shutter will cause a more
blue fl ame, but can cause fl ame lifting from the burner ports.

The fl ame may not appear yellow immediately; allow 15 to 30
minutes for the fi nal fl ame color to be established.
NOTE: It is important that
the venturi sits down tight
on the orifi ce. The burner
is adjustable up/down to
ensure this.
