Maintenance Instructions - L.B. White Premier 350 Owner's Manual And Instructions

Maintenance Instructions

BEFORE EACH USE:
■ Check the area surrounding the heater to
ensure it is clear and free of combustible ma-
terials, gasoline, and other fl ammable vapors
and liquids.
■ Have your gas supplier check all gas connec-
tions 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 elec-
trical components within the heater for corro-
sion, 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
■ Check the heater's fan drive belt. Make sure
the belt is not cracked. If so, replace it. Addi-
tionally, ensure the belt is not slipping, that belt
tension is proper, and sheaves are properly
aligned and not worn.
■ Review all heater markings (i.e. wiring dia-
gram, warnings, start-up, shut-down, trouble-
shooting, 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.

MONTHLY
■ Lubricate the bearings once a month. Use
NLGI grade 2 mineral oil lithium or lithium base
grease.
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 both manual reset high limit heat switches
to ensure proper operation. (See Testing instruc-
tions for same in this owner's manual.)
