Cleaning Instructions
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 back
fl
ashing in venturi tube or air housing.
■
Burner
fl
ame appearing beyond outer cone.
CLEANING WITH BACKPACK BLOWERS
For general cleaning when the heaters do not
have heavy accumulations of dust or dirt, use a
backpack type of 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, then clean the heater
using the Compressed Air Cleaning method.
CLEANING WITH COMPRESSED AIR
(See Fig. 9)
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 as-
sembly.
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.

CLEANING WITH WATER
The following should be accomplished only if the heater
cannot be cleaned adequately by the compressed air
method. DO NOT USE HIGH PRESSURE WASHERS!
FIG. 10
WATER HOSE
1. Position the heater as shown in Fig. 10 and run
water down through the cones and out through the
end of the venturi tube. Then reverse the process as
shown in Fig. 11, on next page.
