Maintenance Instructions Service 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, 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 immediately.
■ Review all heater markings (i.e. wiring diagram, warn-
ings, start-up, shut-down, troubleshooting, etc.) at the
time of maintenance for legibility. Make sure none are
cut, torn, or otherwise damaged. Any damaged mark-
ings 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
necessary.
■ 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.)
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
