FIGURE 6. SHUTTER ADJUSTMENT
With the face removed, you will also need to remove the cooking stones to have clear
access to the burners.
Using a screwdriver, loosen the lock screw (see Figure 6). 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.
Turn on the gas supply valve or open the main valve on the LP cylinder. Following the
lighting instructions, light the burners to be adjusted.
Check that the flame is mostly blue - some random yellow flecks are normal, as is a
muffled “pop” when the burner is turned off.
If the flames are mostly yellow or are
noisy and lift off the burner ports, rotate
the air shutter to progressively reduce
the amount of air entering the venturi.
Continue to 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. Once
confirmed, replace the cooking stones and
faceplate.
B
IMPORTANT: Always ensure that the brass orifices are inserted into the holes in
the ends of the air shutters and centered.
IMPORTANT: Use caution when handling the burner tubes as they can get very
hot. The adjacent surfaces can also get very hot and can cause severe burns. Use
caution when handling components and use protective gloves.
