WARNING
Fire, Burn, and Explosion Hazard
■ This heater contains electrical and mechanical
components in the gas management, safety
and airfl ow systems.
■ Such components may become inoperative or
fail due to dust, dirt, wear, aging, or the cor-
rosive atmosphere of an animal confi nement
building.
■ Periodic cleaning and inspection as well as
proper maintenance are essential to avoid
serious injury or property damage.
1. Before cleaning, close fuel supply valve to
heater and disconnect electrical supply.
2. The heater should have dirt or dust removed
periodically:
a. After each fl ock or between building re-popula-
tion, give the heater a general cleaning using
compressed air or a soft brush on its interior
and exterior. At this time, dust off the motor
case to prevent the motor from over-heating
and shutting the heater down.
b. At least once a year, give the heater a
thorough cleaning. At this time, remove the fan
and motor assembly and brush or blow off the
fan wheel, giving attention to the individual fan
blades. Additionally, make sure the burner air
inlet venturi ports and the throat of the casting
are free of dust accumulation and the area
between the heat chamber top and inside case
is also free of dust.
c. When washing with water, observe and obey
the Warning within these Cleaning Instruc-
tions. This same Warning is also supplied on
the heater.
