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 pizza oven
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 Clean the Air Shutter:
It is possible to visually inspect the air shutter from
below without dismantling the unit. The air shutter
is located directly behind the control valve for that
burner (See figure 9, air shutters A and E).
Turn off the gas supply shutoff valve or close the main
valve on the LP cylinder. Ensure the pizza oven control
knobs are in the OFF position. CAREFULLY rotate
and move that corner of the pizza oven to extend no
more than 6 inches off the edge of the countertop
(See figures 10 and 11). Use a flashlight to view the
screened openings of the air shutter from below.
Remove any obvious obstructions from the screen
protecting the air shutter.
To Adjust the Air Shutter:
It is possible to adjust the air shutter from below
without dismantling the unit. The air shutter is located
directly behind the control valve for that burner (See
figure 9).
Turn off the gas supply shutoff valve or close the main
valve on the LP cylinder. Ensure the pizza oven control
knobs are in the OFF position. CAREFULLY rotate
and move that corner of the pizza oven to extend no
more than 6 inches off the edge of the countertop
(See figures 10 and 11). Use a screwdriver to loosen
the lock screw (Figure 9: B, F). Be careful not to
remove the lock screw. Once loose, you can rotate
the air shutter to adjust the amount of air entering the
venturi.
Visually inspect that the gas hose has not been
stressed, dislodged or otherwise affected by moving
the pizza oven. If it is safe to do so, and with the
pizza oven control knobs in the OFF position, turn on
the gas supply valve or open the main valve on the
LP cylinder. Light the burner to be adjusted. LIGHT
ONLY THE BURNER TO BE ADJUSTED. Rotate the
air shutter to adjust the amount of air entering the
venturi.

For a lifting flame, progressively close the air shutter
until the flame no longer lifts from the burner. For a
sooty flame, progressively open the air shutter until
the flame burns cleanly.
Once adjusted to a stable flame that burns cleanly
and does not lift, turn the pizza oven control knob to
the OFF position. Tighten the lock screw. Re-light and
confirm the adjustment is good. Turn the pizza oven
control knob to the OFF position. Turn off the gas
supply shutoff valve or close the main valve on the LP
cylinder. Return the pizza oven to its normal position
on the countertop. Once again, visually inspect that
the gas hose has not been stressed, dislodged or
otherwise affected by moving the pizza oven.
IMPORTANT:
If the flame from the upper burner is
contacting the ceiling inside the pizza oven, contact
Kalamazoo Outdoor Gourmet Customer Service. You
may have higher than normal gas pressure and may
need a smaller orifice for this burner.
To Adjust Burner LOW Settings (Lower
Burner):
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 insert the screw driver
into the opening in the center of the valve stem (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.
