INSPEcTING BURNERS
Check pilot flame pattern and burner flame patterns often.
PILOT ASSEMbLY
The pilot assembly is factory preset for the proper flame height.
Alterations may have occurred during shipping and handling. Call
a qualified service person to readjust the pilot if necessary.
The height of the thermopile must be 3/8" to 1/2" above the pilot
flame as shown in Figure 55. The thermocouple must be at a height
of about 1/8" above the pilot flame. The flame from the pilot burner
must extend beyond both the thermocouple and thermopile.
If you pilot assembly does not meet these requirements:
• turn fireplace off (see To Turn Off Gas to Appliance, page 22)
• see Troubleshooting, page 25
bURNER FLAME PATTERN
Burner flames will be steady; not lifting or floating. Flame patterns
will be different from unit to unit and will vary depending on instal-
lation type and weather conditions.
If the vent configuration is installed incorrectly, the flames will lift
or "ghost". This can be dangerous. Inspect the flames after instal-
lation to ensure proper installation and performance.
Figure 56 shows a typical flame pattern for these models.
If burner flame pattern differs from that described:
• turn fireplace 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 film 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 first 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, page
19, 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 28).
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 19). Vacuum all glass pieces with
a shop vac.
CAUtION: Do not vacuum if pieces are hot.
Use only the tempered glass door replacement intended for this
fireplace (see Replacement Parts, page 28 for detail on ordering).
