INSPECTING bURNERS
Check pilot ame pattern and burner ame patterns often.

PILOT ASSEMbLY

The pilot assembly is factory preset for the proper ame. Altera-
tions may have occurred during shipping and handling. The pilot
is located on the back right hand side of the burner.
The ame must envelope 1/4" of top of the ignitor/sensor and
grounding stem.
If your pilot assembly does not meet these requirements:
Turn the adjustment screw marked PILOT clockwise to decrease
or counterclockwise to increase the ame to proper size (see
Figure 47, page 22). Do not remove the adjustment screw.
see Troubleshooting, page 25

bURNER FLAME PATTERN

Burner ames will be steady; not lifting or oating. Flame patterns
will be different from unit to unit and will vary depending on instal-
lation type and weather conditions.
If the vent conguration is installed incorrectly, the ames will lift
or "ghost". This can be dangerous. Inspect the ames after instal-
lation to ensure proper installation and performance.
Figure 50 shows a typical ame pattern.
If burner ame pattern differs from that described:
turn replace off (see To Turn Off Gas to Appliance, page 22)
see Troubleshooting, page 25

Glass must be cleaned periodically. During start-up it is normal for
condensation to form on the inside of the glass causing lint, dust,
and other airborne particles to cling to the glass surface. During
initial start-up a slight lm may form on the glass due to paint cur-
ing. The glass should be cleaned several times with a non-ammonia,
nonabrasive household cleaner and warm water after the rst two
weeks of operation. Thereafter, clean the glass two or three times
during each heating season, depending on the usage and circum-
stances present. Refer to Removing/Replacing Glass Door on page
18 of this manual when removing glass door for cleaning.
WARNING: Only parts supplied by the manufacturer
should be used when replacing broken or damaged
glass door panel (see Replacement Parts, page 27).
This glass door panel is a complete unit. No substitute
materials may be used.
CAUtION: Wear gloves and safety glasses while
handling or removing broken glass. Do not remove if
glass is hot. keep children and pets away from glass.
If glass has been broken, carefully remove glass door (see Remov-
ing/Replacing Glass Door, page 18). Vacuum all glass pieces with
a shop vac.
CAUtION: Do not vacuum if pieces are hot.
