Burner Adjustments
IMPORTANT:
A sooty flame is usually caused by dirt, debris or spider nests blocking the air shutter or orifice.
This is a dangerous condition. The grill should NOT be used until the problem is rectified. If you are not
comfortable addressing the issue yourself, please hire a qualified technician or contact Kalamazoo Outdoor
Gourmet Customer Service at +1.800.868.1699.
To Adjust the Main Burner Air Shutter:
The main burner air shutters are easily accessed after carefully removing the main control panel (see page
44). Ensure all of the control knobs on the grill are in the OFF position. Remove the control knobs from the
main control panel, and then remove the two quarter-turn fasteners that secure the control panel (see Figure
22:C). Carefully lower the control panel to disengage it from the keyways on the
body of the grill (see Figure: 22:E). You can rest the control panel
on the cleanout tray while you disengage the wiring harness
connections to free the control panel.
Adjust the main burner air shutters (see Figure 20:A) by
loosening the lock screw (see Figure 20:B). The grill is
factory adjusted so that the air shutter is about 50%
open. If the flames are too orange, the burners may
need more combustion air. Adjust the air shutter to a
more open position.
Too much air may cause the flames to “lift off” the
burner. This is a dangerous condition that must be
avoided. Do not open the air shutter too far. Too
much air will also make it more difficult to light the
burner. You may test burn the grill to fine-tune the air
shutter by mounting the control knob without re-installing
the control panel. You will have to light the burner manually
because the electronic ignition system is disengaged. Light only
the burner to be adjusted and fine-tune the air shutter. Adjustments
should be made with the burner on HIGH.
Once adjusted to a stable flame that burns cleanly and does not lift, turn the burner OFF. Tighten the lock screw.
To Adjust Burner LOW Settings (All Burners):
The low setting on the main burners can be adjusted WITHOUT removing
the control panel. A long and thin flat-blade screw driver is needed to make
the adjustments. Light the burner and set it to LOW.
Remove the control knob and the valves stem insert (if applicable). Insert
the screw driver into the opening in the center of the valve stem (see Figure
20:C, Figure 21:A). Turn the adjustment screw until the flame on the burner
is the minimum stable flame height. The flame should be steady at all
ports around the burner. The flame should not be easily blown out without
quickly reestablishing itself.
