Air shutters are preset at the factory based on the gas the
sideburner is built to burn. However, altitude or other local
conditions may require air shutter adjustment for proper
combustion.
The fl ames from a properly adjusted sideburner will touch
the burner ports and appear mostly blue.
If the fl ames are orange, “lazy”, or lift off the burner ports,
then adjust the sideburner air shutter using the following
steps.
The air shutters are located at the end of the burner
assemblies, behind the control panel. They can safely and
easily be adjusted while the unit is lit.
CAUTION: Do not touch the sideburner surrounding
top area, as it will be hot while adjusting
the air shutter.
1.
Remove the control panel. See the CONTROL PANEL
REMOVAL section for details.
2. Replace the control knobs back on to the valve stems.
3. Light the sideburner following the LIGHTING
INSTRUCTIONS section.
4. Loosen the
front burner air shutter adjustment screw,
then use the tip of a screwdriver to open or close the
air shutter until the fl ames appear blue and touch the
burner ports.
5. Retighten the adjustment screw.
6. Repeat for rear burner air shutter.
Should you have diffi culty accessing the
rear burner air shutter, you may shut down,
remove the rear burner (when cool), then
adjust the air shutter to the same opening
as the already adjusted front burner. (See
CONVERT/CHECK SIDE BURNER ORIFICE
section to remove rear burner.) Be sure
to properly reinstall rear burner when
complete.
7. Once all adjustments are complete; be sure the
unit is off and remove the knobs, then replace
the control panel and knobs.
