WARNING
This heater may be washed only on the external case
assembly 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.
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 or cloth, or compressed air.
1. Before cleaning, shut off all
gas supply valves and
disconnect electrical supply.
2. The heater should have dirt or dust removed
periodically:
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
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 Instructions. This
same Warning is also supplied on the heater.

Cleaning Instructions
Maintenance 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. The area surrounding the heater shall be kept clear
and free from combustible materials, gasoline, and
other flammable vapors and liquids.
2. Have your gas supplier check all gas piping annually
for leaks or restrictions in gas lines.
3. 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 heater.
4. Regulators can wear out and function improperly.
Have your gas supplier check the date codes on all
regulators installed and check delivery pressures to
the heater to make sure that the regulator is reliable.

5. Check all wiring, associated terminals, and electrical
components within the heater for corrosion, frayed or
cut insulation, tight connections, etc. Repair or
replace as necessary.
6. Review all heater markings (i.e. wiring diagram,
warnings, start-up, shut-down, troubleshooting, etc.)
at the time of maintenance for legibility. Make sure
none are cut, torn, or otherwise damaged. Any
damaged markings must be replaced immediately by
contacting the L.B. White Co., Inc. Dataplates, start-
up and shut-down instructions and warnings are
available at no cost. A nominal charge will be applied
for wiring diagrams.
