Tradesman Construction Heaters
WARNING
Do not use a pressure washer, water, or liquid clean-
ing 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 fi re 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 fl ammable vapors and liquids.
■ 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, reloca-
tion, 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 immediately.
■ 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. Data plate, startup and shut-down instructions and
warnings are available at no cost.
ANNUALLY:
■ Clean and check the igniter for cracks. Replace if neces-
sary.
■ 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.
■ Test the auto reset high limit switches to ensure proper
operation. (See Testing instructions for same in this
owner's manual.)

Service Instructions

WARNING
Burn Hazard
■ Some heater surfaces are hot for a period of
time after the heater has been shut down.
■ Allow the heater to cool before performing
service, maintenance, or cleaning.
■ Failure to follow this warning will result in
burns causing injury.
WARNING
Fire and Explosion Hazard
■ Do not disassemble or attempt to repair any
heater components or gas train components.
■ All component parts must be replaced if
defects are found.
■ Failure to follow this warning will result in
fi re or explosions, causing property damage,
injury, or death.
1. Close the fuel supply valve to the heater and discon-
nect the electrical supply before servicing unless
necessary for your service procedure.
2. Remove the heater's bottom base or side panel for
access to electrical components and connections.
3. Disconnect the appropriate electrical leads for the
component being replaced.
4. Remove the fan guard and motor/fan assembly for
access to upper barrel components.
5. The auto reset high limit switches, and thermostat
can be tested by disconnecting the leads at the
component, and placing a jumper connecting the
leads together.:
-- Reconnect the electrical supply and open fuel supply
valves.
-- If the heater lights, the component is defective and
must be replaced.
-- Do not leave the jumper on or operate the heater if the
part is defective. Replace the part immediately.
-- An alternate method for checking the components is to
perform a continuity check.
6. The air proving switch must not be jumpered. If
jumpered, the ignition control will not allow heater
operation. Test the air proving switch for continuity. If
defective, replace the switch
