L.B. White I-34 Infraconic Pilot Ignition - Manual (Page 12)

Clean the heater and optional dust filter on a regular basis
to maintain proper combustion and to eliminate future
problems.
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 injector body.
■
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 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 down.
2. Using a soft bristle brush, brush off all exterior
surfaces of the heater. Pay particular attention to the
air inlet hole on the injector body and pilot bracket.
3. Direct the air at the combustion cones, working your
way around entire surface of cone assembly.
4. Blow air through air inlet opening in the venturi tube
to b l ow b a c k o u t a ny l o o s e n e d d u s t t h ro u g h
combustion cones.
5. Repeat Steps 3 and 4 until the cones and the venturi
tube are no longer emitting dust.
6. Inspect the cones, pilot bracket, and venturi tube to
make sure these areas are clean.
7. Return the heater to its normal hanging position and
relight the heater.

CLEANING WITH WATER (Continued on page 13)
The following should be accomplished only if the heater
cannot be cleaned adequately by the compressed air
method. DO NOT USE HIGH PRESSURE WASHERS!
1. Wrap the pressure switch, gas regulator, and pilot
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. 9.
FIG. 9
3. Position the heater as shown in Fig. 10 and run water
down through the venturi tube and out through
combustion cones.

WATER HOSE
CAUTION
■
Disinfectants utilized in agricultural animal
confinement buildings may contain chemicals
damaging to components of the heater.
■
Protect the pilot gas control valve, pressure valve, and
pilot relight 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.
