L.B. White I-40 Infraconic Spark Ignition - Manual (Page 13)

It is important to clean the heater and the optional dust
filter on a regular basis to maintain proper combustion and
to eliminate future problems. Do not clean the heater with
water or other liquids.
The frequency of cleaning will var y depending upon
livestock being raised and overall ventilation of the building.
Problems associated with lack of cleaning typically are:
■
Black soot on inside of canopy.
■
Gas backflashing in venturi tube or air housing.
■
Burner flame appearing beyond outer cone.
A. HEATER
CLEANING WITH BACKPACK BLOWERS
AND HEATER BLOWER
Blower Part No. 21170
For general cleaning when the heaters do not have heavy
accumulations of dust or dirt, use either a backpack type of
blower or the heater blower.
Follow the same procedures for cleaning as listed for
“Cleaning with Compressed Air”.
If the dust and dirt cannot be removed effectively using the
backpack blower or heater blower, then clean the heater
using the Compressed Air cleaning method which follows.
CLEANING WITH COMPRESSED AIR
1. Turn off the gas supply to the heater and let the
heater cool down.
2. Direct the air at the combustion cones, working your
way around entire surface of cone assembly.
See Fig. 8.
3. Blow air through air inlet opening in the air housing to
blow back out any loosened dust through combustion
cones.
4. Repeat Steps 2 and 3 until the cones and the venturi
tube are no longer emitting dust.
5. Inspect the cones and venturi tube to make sure
these areas are clean.
6. Return the heater to its normal hanging position and
relight the heater.

B. FILTER (ACCESSORY)
1. During Continued Heater Use
- Remove filter and shake off dust.
- Do not squeeze or tap filter while filter is installed on
heater. Doing so will allow dust to be blown into venturi
tube or combustion cones.
2. A f t e r C o n t i n u e d H e a t e r U s e o r B e f o r e B u i l d i n g
Repopulation
- Remove filter and shake off dust.
- Use compressed air or standard water faucet pressure
to clean it.
- Do not use high pressure water, air, or a washing
machine as filter material damage may occur.
- If water is used, squeeze out excess water from filter
before installation.
- Let filter dry before lighting heater.
