MAINTENANCE

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 satisfactory. 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 colour 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.
