The air shutter, located at the base of the
main burner (see Figure 54), 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 55). 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.

PILOT/ELECTRODE ASSEMbLy ADjUSTMENT
The pilot assembly is factory preset for the
proper flame height. Alteration to these set
-
tings may have occurred during shipping
and handling. If this is the case, some minor
adjustment may be necessary and should be
done by a qualified technician. To access pilot
assembly, glass door must be opened. The
proper settings for thermopile height should
be at a distance of 3/8" to 1/2" from pilot flame
as shown in Figure 52.
The electrode is installed at the factory for
proper positioning. However, alterations to
position may have occurred due to shipping
and handling. These settings may need
adjustment and must be done by a qualified
technician. The correct position and height is
as shown in Figure 53.
