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, corrosive
environment, 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 the electrical supply.
2. The heater should have dirt or dust removed
periodically:
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 assembly and brush or blow
off the fan blade assembly. Additionally, make
sure the burner air inlet venturi ports and the
casting are free of dust accumulation.
WARNING
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, gasoline, and other flammable vapors and
liquids.
■ At the installation ensure there is adequate combus
-
tion air and the ventilation air flow 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 regulator
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.
■ Check the hose assembly after heater installation, re
-
location, and when the heater is in use. If it is evident
there is excessive abrasion or wear, or if the hose is
cut, it must be replaced prior to the heater being put
back into operation.
■ 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., LLC. The data plate, startup and shutdown
instructions, and warning stickers are available as a
replacement part.
ANNUALLY:
■ Clean and check the igniter for cracks. Replace if
necessary.
■ Regulators can wear out and function improperly.
Have your gas supplier check the regulators
outlet pressure to make sure it is adjusted correctly.
■ Test both high limit switches, if applicable, to ensure
proper operation. See Service Instructions in this
owner’s manual.
