1.  Follow the safety precautions and steps for 

main burner removal  
in the CHANGING 
THE MAIN BURNER 
ORIFICES section 
(steps 1-4).

2.  Adjust the air shutter 

opening by loosening 
the adjustment screw 
with a screwdriver, 
then sliding the air shutter backward or forward 
to open or close the air shutter opening (see 
Fig. 36-2).

Too large an air shutter opening will allow too much 
air into the burner, which will cause the fl ames fi rst 
to shorten and then to appear to lift up off the ports. 
For the bottom of the fl ames to move closer to the 
ports, close the air shutter more.

If the air shutter opening is too small or closed, the 
fl ames will present consistently orange tips and 
become “lazy,” slowly undulating back and forth.

For propane gas, ideal settings tend to be just 
slightly open. For natural gas, which generally 
requires less primary air than propane, the main 
burner air shutter may be nearly closed.

3.  Adjust the air shutter opening and then replace 

the burner (steps 6-8 in the CHANGING THE 
MAIN BURNER ORIFICES section)

4.  Follow the lighting instructions in this manual to 

light the burner. 

5.  Repeat steps 1-4 until the fl ames appear to 

touch the burner ports, burning fairly steadily 
and mostly blue (see Fig. 36-1).

Air shutters are preset at the 
factory based on the gas the grill is 
built to burn. However, altitude or 
other local conditions may require 
air shutter adjustment for proper 
combustion.

Flames from a properly adjusted main burner with 
no wind or breeze present will appear fairly steady, 
consistent, and mostly blue. If the tip of a fl ame were 
to turn orange, it should only do so briefl y and then 
become blue again. The fl ames will appear to burn 
while touching the burner ports  (see Figure 36-1).

If the fl ames have orange in them and appear to 
undulate slowly from side to side, or if some of them 
appear to lift off the burner instead of touching it,  
then adjust the air shutter, as instructed below.

CAUTION: Turn all burner control knobs to the 

OFF position and turn off the gas 
supply at the source before removing 
or adjusting a burner. 

Wait for the burner to be cool or use heavily insulated 

heat-resistant gloves when handling the burner.
