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.
CLEANING WITH BACKPACK BLOWERS
AND HEATER BLOWER
Blower Part No. 130-21170
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 until you can no longer feel heat
coming from the heater canopy or combustion cones.
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.
3. Turn on the compressed air and point the nozzle
directly at the combustion cones, working your way
around entire surface of cone assembly. This
procedure may take about a minute or slightly longer
depending on amount of dust or dirt on combustion
cones. See Fig. 6.
4. Shoot compressed air through air inlet opening in the
venturi tube to blow back out any loosened dust
through combustion cones.
5. Repeat Steps 3 and 4 until the cones and the venturi
tube are no longer emitting dust.
6. Visually inspect the cones and venturi tube to make
sure these areas are clean.
7. Return the heater to its normal hanging position.
8. Relight the heater.

Cleaning Instructions
ATTENTION
Combustion problems associated with lack of cleaning
typically are:
■ Sooting on inside of canopy.
■ Burner flame appearing beyond outer cone.
