DECORATIVE FACING
Any noncombustible material may be used
for facing (glass, tile, brick, etc.) as long as
the proper clearances are observed (see
Clearances, page 4).
IMPORTANT:
Lou-
vered openings must not be obstructed, and
upper and lower panels must remain remov-
able for servicing. Use only heat-resistant,
noncombustible mortar or adhesive when
securing facing material.
Note:
Combustible material, such as wood,
that has been fireproofed is not considered
noncombustible.

PILOT 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 the
pilot assembly, the glass door must be opened.
The proper settings for the thermopile height
should be at a distance of 3/8" to 1/2" from the
pilot flame as shown in Figure 47.
BURNER FLAME
ADJUSTMENT
Figure 47 - Correct Pilot Flame Pattern
The air shutter, located at the underside of the
main burner (see Figure 48), has been factory
preset to the proper air-to-gas ratio which
results in an even, clean burning flame across
the burner (see Figure 49). 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 nor-
mal setting is “full opened”. Do not forget to
retighten the air shutter screws.
