ADjUSTMENT
The air shutter, located at the base of the main
burner (see Figure 51), has been factory preset to
the proper air-to-gas ratio which results in an even,
clean burning flame across burner (see Figure 52).
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
air shutter screw.
