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 28. 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 your pilot assembly does not meet these requirements:
• turn fireplace off (see To Turn Off Gas to Appliance, Page 16)
• see Troubleshooting, Page 20

NOTICE: Do not mistake orange flames with yellow
tipping. Dirt or other fine particles are burned by ap-
pliance, causing brief patches of orange flame.

If burner flame pattern is incorrect, as shown in Figure 30.
• turn appliance off (see To Turn Off Gas to Appliance, Page 16)
• see Troubleshooting, Page 20
WARNING: Turn off appliance and let cool before
cleaning.
CAUTION: You must keep control areas, burners and
circulating air passageways of appliance clean. Inspect
these areas of appliance before each use. Have appli-
ance inspected yearly by a qualified service person.
WARNING: Failure to keep the primary air
opening(s) of the burner(s) clean may result in sooting
and property damage.
Perform a periodic visual check of pilot and burner
flame.
BURNER INJECTOR HOLDER AND PILOT AIR INLET HOLE
The primary air inlet holes allow the proper amount of air to mix with
the gas. This provides a clean burning flame. Keep these holes clear
of dust, dirt, lint and pet hair. Clean these air inlet holes prior to each
heating season. Blocked air holes will create soot. We recommend
that you clean the unit every three months during operation and have
appliance inspected yearly by a qualified service person.
We also recommend that you keep the burner tube and pilot assembly
clean and free of dust and dirt. To clean these parts we recommend
using compressed air no greater than 30 PSI. Your local computer
store, hardware store or home center may carry compressed air in a
can. If using compressed air in a can, please follow the directions on
the can. If you don’t follow directions on the can, you could damage
the pilot assembly.
1. Shut off unit, including pilot. Allow unit to cool for at least thirty
minutes.
2. Inspect burner, pilot and primary air inlet holes on injector holder
for dust and dirt (see Figure 31, Page 18).
3. Blow air through the ports/slots and holes in the burner.
4. Check injector holder located at end of burner tube again. Remove
any large particles of dust, dirt, lint or pet hair with a soft cloth or
vacuum cleaner nozzle.
5. Blow air into the primary air holes on the injector holder.
6. In case any large clumps of dust have now been pushed into the
burner repeat steps 3 and 4.
