FLAME HEIGHT ADJUSTMENT
Flames should be blue and stable with no 
yellow tips, excessive noise or lifting (Note: 
LP units may have some yellow tipping). If 
any of these conditions exist, check the air 
shutter and burner ports are clear. If cleaning 
these does not improve performance, the air 
shutter can be adjusted.

Reinstall the U-burner and light 
to check. If the flame is blue and 
stable, remove the burner, tighten 
the air shutter screw and replace all 
parts. If flame is still unstable, repeat 
the above steps.
Ensure the griddle is 
OFF and cool.
To access the air shutters, remove 
the griddle plate. Refer to page 7 
for guidance. 
With a screw driver, loosen the lock 
screw on the face of the air shutter 
so it can be adjusted. If the flame is 
yellow turn the air shutter counter-
clockwise, if the flame is noisy and 
tends to lift turn the air shutter 
clockwise.
