CLEANINg AND
MAINTENANCE
WARNING: Turn off heater
and let cool before cleaning.
CAUTION: You must keep
control areas, burner, and circu-
lating air passageways of heater
clean. Inspect these areas of
heater before each use. Have
heater inspected yearly by a
qualified service person.
CAUTION: You must check
and keep burner/venturi tubes
clean of insect and insect nest. A
clogged tube can lead to a fire.
WARNING: Failure to keep
the primary air opening(s) of
the burner(s) clean may result in
sooting and property damage.
ODS/PILOT AND BURNER
Use a vacuum cleaner, pressurized air, or
small, soft bristled brush to clean.
BURNER PILOT AIR INLET
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, and lint. 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 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. You can use a vacuum cleaner in the
blow position. 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.
Always keep the heater area clear and free
from combustible materials, gasoline and
other flammable vapors and liquids.
114082-01F
Keep the vent areas (slots in the bottom and the
top at the front of heater) clear at all times.
Visually inspect the pilot flame and burner
periodically during use. The burner should
be bright orange without a noticeable flame.
If the burner has a noticeable flame, cleaning
may be required. Use the following procedure
to inspect burner assembly.
It is necessary to periodically check the burner
orifice and burner venturi tube to make sure
they are clear of insects, nests or spider webs
that may accumulate over time. A clogged
tube can lead to a fire.
1. Allow heater to thoroughly cool before
performing any maintenance.
2. Turn control knob to the OFF position and re-
move disposable 1 lb. cylinder from heater.
3. Remove four screws securing burner as-
sembly to base assembly (see Figure 3,
page 5).
4. Remove burner assembly from base as-
sembly.
5. Inspect interior of burner assembly for
accumulation of dust, lint or spider webs.
If necessary, clean interior with a vacuum
cleaner or apply air pressure. Do not
damage any components within burner
assembly when you are cleaning.
6. Inspect and clean main burner orifice by
using a vacuum or apply air pressure at
orifice opening.
7. Inspect and clean pilot (mounted to
bracket) by using a vacuum or apply air
pressure through the air holes in the pilot
(see Figure 4).
dles, wires, or similar cylindrical
objects to clean the pilot to avoid
