Cleaning And Maintenance - Desa CCL3924NR Owner's Operation And Installation Manual

WARNING: Turn off heater
and let cool before cleaning.
CAUTION: you must keep
control areas, burners and
circulating air passageways
of heater clean. Inspect these
areas of heater before each use.
Have heater inspected yearly
by a qualified service person.
Heater may need more frequent
cleaning due to excessive lint
from carpeting, pet hair, bedding
material, etc.
WARNING: Failure to keep
the primary air opening(s) of
the burner(s) 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 provides
a clean burning flame. Keep these holes clear
of dust, dirt, lint and pet hair. Clean these air in-
let 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 heater 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 com-
pressed 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 37).
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 burner repeat steps 3 and 4.
Clean pilot assembly also. A yellow tip on
pilot flame indicates dust and dirt in the pilot
assembly. There is a small pilot air inlet hole
about 2" from where the pilot flame comes out
of the pilot assembly (see Figure 38). With the
unit off, lightly blow air through the air inlet
hole. You may blow through a drinking straw
if compressed air is not available.

LOGS
• If you remove logs for cleaning, refer to
Installing Logs, page 18, to properly replace
logs.
• Replace log(s) if broken or chipped (dime-
sized or larger).
MAIN BURNER
Periodically inspect all burner flame holes
with heater running. All slotted burner flame
holes should be open with yellow flame pres-
ent. All round burner flame holes should be
open with a small blue flame present. Some
burner flame holes may become blocked by
debris or rust, with no flame present. If so,
turn off heater and let cool. Remove blockage.
Blocked burner flame holes will create soot.
