Burner Adjustments; Valve Adjustments - Kalamazoo K750GS Use And Care Manual

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 Starter Burner Air Shutters:
The starter burner air shutters are easily accessed
inside the base cabinet of the grill. Ensure the gas
supply has been turned off at the source. Adjust
the air shutters (Figure 21:A) by loosening the lock
screw (Figure 21: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. 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 Clean the Ignition Burner Air Shutter:
Gently brush away debris from the screen (see Figure 27:C) using an old toothbrush.
Cooktop Burners Do Not Require Any Air Mixture Adjustment
To Adjust Burner LOW Settings (All Burners):
The low setting all burners can be adjusted using a long and thin flat-blade screw
driver. First, light the burner and set it to LOW. Next, remove the control knob by
pulling it outward until it slides off the valve stem. Insert the screw driver into the
opening down the center of the valve stem and into the adjustment screw (Figure
22: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.
