L.B. White I-40 Infraconic Ignition - Manual (Page 12)

It is important to clean the heater on a regular basis to
maintain proper combustion and to eliminate future
problems.
The frequency of cleaning will vary 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 injector body.
■ Burner flame appearing beyond outer cone.

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 either the Compressed Air or Water Cleaning methods.
CLEANING WITH COMPRESSED AIR
1. Turn off the gas supply to the heater and let the
heater cool.
2. Direct the air at the combustion cones, working your
way around entire surface of cone assembly.
3. Blow air through air inlet opening in the venturi tube
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.

1. Wrap the pressure switch and safety control valve
with a plastic bag to protect these components from
entry of water.
2. Using a standard garden hose with standard faucet
pressure, spray water against the cones to wash out
the build up of dust in the cones and the venturi tube.
Work your way around the entire cone assembly.
See Fig. 10.

3. Position the heater as shown in Fig. 11 and run water

combustion cones.

Disinfectants utilized in agricultural animal
confinement buildings may contain chemicals
damaging to components of the heater.
■ Protect the safety gas control valve and pressure
valve by wrapping these components with a plastic
bag before disinfecting.
■ Always make sure to remove the plastic bag or other
protective covering before start up.
