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 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 periodi-
cally:
a. After each flock or between building re-population,
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 clean-
ing. 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 Instructions. This same
Warning is also supplied on the heater.
WARNING
This heater may be washed only on the external case
assembly when provided:
A. The heater is disconnected from the electrical supply.
B. All access panels are securely closed.
C. Water spray nozzle shall not discharge within 6 feet
of the heater.
D. The water pressure does not exceed 45 PSIG for 10
seconds on each side of heater.
E. The heater is not reconnected to electrical supply for
a minimum of 1 hour or until the heater is thoroughly
dry.
Maintenance Instructions
1. Have your gas supplier check all gas piping annually
for leaks or restrictions in gas lines. Also, at this time
have your gas supplier clean out the sediment trap of
any debris that may have accumulated.
2. The heater’s surrounding area shall be kept clear and
free from combustible materials, gasoline, and other
flammable vapors and liquids.
3. Regulators can wear out and function improperly. Have
your gas supplier check the date codes on all regula-
tors installed and check delivery pressures to the
appliance to make sure that the regulator is reliable.
4. Regulators must be periodically inspected to make
sure the regulator vents are not blocked. Debris,
insects, insect nests, snow, or ice on a regulator can
block vents and cause excess pressure at the appli-
ance.
5. Review all heater markings (ie. warnings, start-up/
shutdown, electrical wiring, diagrams, etc.) for legibility.
Ensure that none are cut, torn, or otherwise damaged.
Any damaged markings must be replaced immediately
by contacting L.B. White Co., LLC. Markings are avail-
able at no cost.
6. Inspect gas hoses for nicks,cuts, or corroded fittings.
Replace the complete gas hose assembly
if defects are found.
7. Inspect the heater’s electrical connections. Replace
any terminals that are corroded.
WARNING
Improper cleaning of the heater can cause severe
personal injury or property damage due to water and/
or cleaning solution:
1. In electrical components, connections and wires
causing electrical shock or component failure.
2. On gas control components causing corrosion
which can result in gas leaks and fire or explosion
from the leak.
Clean internal components of the heater with a soft,
dry brush, cloth, or compressed air.
