Cleaning Instructions

WARNING
Fire, Burn and Explosion Hazard
■ This heater contains electrical and mechanical
components in the gas management, safety and
airflow systems.
■ Such components may become inoperative or
fail due to dust, dirt, wear, aging, or the corrosive
atmosphere of an animal confinement building.
■ Periodic cleaning and inspection as well as
proper maintenance are essential to avoid seri-
ous injury or property damage.
1. Before cleaning, close the fuel supply valve to the
heater and disconnect the electrical supply. Allow
heater to cool.
2. The heater should have dirt or dust removed periodi-
cally:
a. After each flock or between building re-popula-
tion, give the heater a general cleaning using
pressurized air or a soft brush on its burner box,
reflectors, and tubes.
b. At least once a year, give the heater a thorough
cleaning. At this time, open the burner box and
brush or blow off control components, and fan
motor assembly. Ensure the burner air inlet
venturi ports and the throat of the casting are free
of dust accumulation.
c. When washing with water, do not spray water into
the burner box or the tubes. Observe and obey
the Warning within these Cleaning Instructions.
