Cleaning - Desa CFFP18NT Owner's Operation And Installation Manual

bURNER FLAME PATTERN
Figure 18 shows a correct burner flame pat-
tern. Figure 19 shows an incorrect burner
flame pattern. The incorrect burner flame
pattern shows sporadic, irregular flame tip-
ping. The flame should not be dark or have
an orange/reddish tinge.
Note: When using the fireplace the first time,
the flame will be orange for approximately one
hour until the log cures.
If burner flame pattern is incorrect, as shown
in Figure 21
• turn fireplace off (see To Turn Off Gas to
Appliance, page 17)
• see Troubleshooting, page 19
WARNING: Turn off fireplace
and let cool before cleaning.
CAUTION: You must keep
control areas, burner and cir-
culating air passageways of
fireplace clean. Inspect these
areas of fireplace before each
use. Have fireplace inspected
yearly by a qualified service
person. Fireplace may need
more frequent cleaning due to
excessive lint from carpeting,
pet hair, bedding material, etc.
WARNING: Failure to keep
primary air opening of burner
clean may result in sooting and
property damage.
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 pro-
vides 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 rec-
ommend that you clean the unit every three
months during operation, or as needed, and
have fireplace 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 dam-
age 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 20).
3. Blow air through the ports/slots and holes
in the burner.
4. Check injector holder located at the end of
the burner tube again. Remove any large
particles of dust, dirt, lint or pet hair with
a soft cloth or vacuum cleaner nozzle.
