INSTALLATION
Continued
WARNING: Improper installa-
tion, adjustment, alteration, ser-
vice, or maintenance can cause
injury or property damage. Refer
to this manual. For assistance or
additional information, consult a
qualified installer, service
agency, or gas supplier.
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.

ELECTRODE
ASSEMBLY
ADJUSTMENT
The electrode assembly is factory preset for
proper operation. Alteration to these settings
may have occurred during shipping and han-
dling. If this is the case, some minor adjust-
ments may be necessary and should be done
by a qualified technician. To access the elec-
trode, the glass door must be opened. The
proper settings for the electrode height should
be at a distance of 5/8" from the top of the
burner as shown in Figure 48.
BURNER FLAME
ADJUSTMENT
The air shutter, located at the underside of the
main burner (see Figure 50), has been factory
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 nor-
mal setting is “full opened”. Do not forget to
retighten the air shutter screws.
