The air shutter, located at the base of the
main burner (see Figure 50), has been fac-
tory preset to the proper air-to-gas ratio which
results in an even, clean burning flame across
the burner (see Figure 51). If readjustment is
necessary, you can restore the proper air-to-
gas ratio by loosening the air shutter screw
and rotating the air shutter until the proper
flame setting is achieved (the shutter's normal
setting is fully open. Do not forget to retighten
the air shutter screw.
