Air Shutters
Air shutter adjustments are pre-set at the factory. However depending on a variety of factors including the type of gas supply, these
adjustments may need to be fine-tuned after installation. A qualified installer should make these adjustments at the time of installation.
Any air shutter adjustments that are needed after installation are not covered by your warranty.
Air Shutter Checklist
Before making any adjustments to the air shutters, verify the following:
1.
Rangetop is completely cool.
2.
Gas source type (natural gas or liquid propane) and pressue matches the serial plate and is set properly. This setting is typically
checked and adjusted by a service technician using a manometer.
3.
Gas pressure regulator is set properly to natural gas or liquid propane.
4.
Orifice is aligned and parallel with the venturi tube to the burner, the venturi is properly positioned over the orifice, and that the
burner is properly seated.

DJUSTMENT
A properly adjusted burner will have sharp conical shaped blue flames.
However, on some larger burners (22,000 BTU or 25,000 BTU) the cones
are close together and blend into one another. The flame should be almost
all blue. If your flames do not appear, follow the instructions to adjust the
air shutter.
TIP
Propane gas sometimes produces a yellow tipped flame. This is normal.
Before you begin, follow the steps in the Air Shutter Checklist.
Make sure burner is cool.
1.
Remove the ring grate, top grate, griddle or charbroiler associated with the burner(s) that need adjusting.
2.
Remove the burner to expose the air shutter adjustment screw in the burner cavity.
3.
Use a Phillips screwdriver to loosen the air shutter tightening screw.
4.
Use your fingers to adjust the air shutter gap:
O
Widen the gap to remove yellow tips and to eliminate a lazy flame
O
Reduce the gap to remove a lifting flame.
5.
Tighten the air shutter screw and replace the burner.
6.
Test it to make sure the adjustments have corrected the issue.
7.
If needed, turn off the burner and repeat steps 3 and 4.
