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.
■
At the installation ensure there is adequate
combustion air and the ventilation air
fl
ow 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, relocation, 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 replace-
ment 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 the manual reset high limit heat switch to
ensure proper operation. (See Testing
Instructions located in the Service
Instructions on page 21.)
