Cleaning And Maintenance - Superior TF18NE Installation And Operation Instructions 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 quali-
fied 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 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 46).
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.
Clean pilot assembly also. Additional clean-
ing may be needed for proper pilot operation
based on use/lack of use. A yellow tip on the
pilot flame may indicate dust and dirt in the
pilot assembly. There is a small pilot air inlet
hole about from where the pilot flame comes
out of pilot assembly (see Figure 47). With
unit off, lightly blow air through 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 Embers and Lava Rock,
page 16, 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 flame present. 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.
WARNING: The injector hold-
ers (air shutters) are not adjust-
able. Do not move injector holders
from their original positions.
