supplies. (DO NOT DISCONNECT THE ELECTRI-
CAL SUPPLY UNTIL THE BLOWER FAN MOTOR
HAS CYCLED OFF FROM COOLING THE HEAT
EXCHANGER)
Note: When either the thermostat cycles the heater off
or the selector switch is in the OFF position, the main
fan motor will continue to operate. This is the cool down
post purge of the heat exchanger. During this process
the LED flashes after 90 seconds of post purge, the
heater will shut-off.
Cleaning Instructions
WARNING
Fire, Burn, and Explosion Hazard
■ This heater contains electrical and mechani-
cal components in the gas management, and
safety systems.
■ Such components may become inoperative
or fail due to dust, dirt, wear and aging.
■ Periodic cleaning and inspection as well as
proper maintenance are essential to avoid
serious injury or property damage.
1. Before cleaning, shut off all gas supply valves and
disconnect electrical supply.
2. The heater should have dirt or dust removed periodi-
cally:
a. Before each use give the heater a general cleaning
using compressed air or a soft brush or dry rag on
its case and internal components. At this time, dust
off the motor case to prevent the motor from over-
heating.
b. At least once a year, give the heater a thorough
cleaning. At this time, remove the fan and motor as-
sembly and brush or blow off the fan blade assembly.
Additionally, make sure the burner air inlet is free of
dust accumulation.

WARNING
Fire, Burn, and Explosion Hazard
■ Do not use a pressure washer, water, or
liquid cleaning solution on any gas controls.
Use of a pressure washer, water, or liquid
cleaning solution on the control components
can cause severe personal injury or property
damage due to water and/or liquids:
■ In electrical components and wires causing
electrical shock or equipment failure.
■ On gas control valves causing corrosion
which can result in gas leaks and fire or
explosion from the leak.
Clean all components of the heater with pressurized
air, a dry brush, or a dry cloth.
Maintenance
Instructions
BEFORE EACH USE:
■ Check the area surrounding the heater to ensure
it is clear and free of combustible materials, gaso-
line, and other flammable vapors and liquids.
■ At the installation, ensure the flow of combustion
and ventilation air is not obstructed.
■ Have your gas supplier check all gas connections
for leaks or restrictions in gas lines.
■ Inspect the regulator vent to make sure the regula-
tor vent is not blocked. Debris, insects, insect
nests, snow, or ice on a regulator can block vents
and cause excess pressure at the heater.
■ 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.
■ 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 immedi-
ately by contacting the L.B. White Co., LLC. Data
plate, startup and shut-down instructions and warn-
ings are available at no cost. A nominal charge will
be applied for wiring diagrams.
■ Check the main fan drive belt. Make sure the belt
is not cracked. If so, replace it. Additionally, ensure
the belt is not slipping, belt tension is proper and
pulleys are properly aligned and not worn.
■ Check air gate adjustment.
