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 gas regulator vent to make sure
its 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 the hose assembly after heater installa-
tion, relocation and before the heater is put into
use. Ensure proper positioning. (See Fig.2).
■ Ensure the hose is not cut, or if there is exces-
sive abrasion or wear. If so, it must be replaced
prior to the heater being put into operation.
■ Check overall condition of the heater for
cracked, damaged, rusted or corroded compo-
nents, loose screws or bolts, etc. Replace any
suspect components immediately.
■ For safety as well as for optimum performance
of the heater, it is necessary to keep the inside
and the outside of the heater free of dust, dirt,
or any combustible material.
■ Review all heater labels at the time of main-
tenance for legibility. Make sure none are cut,
torn, or otherwise damaged. Any damaged
labels must be replaced immediately by con-
tacting the L.B. White Co., Inc.
ANNUALLY:
■ Regulators can wear out and function improp-
erly. 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.

Service Instructions

WARNING
Burn Hazard
■ Heater surfaces are extremely 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
such as gas valves, or gas hoses.
■ 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 unless it is
necessary to have the valve open for services.
2. In servicing some components, it may be
necessary to remove the gas hose, or fi lter.
3. For reassembly, reverse the respective service proce-
dure. Ensure gas connections are tightened securely.
4. After servicing, light the heater to ensure proper opera-
tion and check for gas leaks.
5. Clean the heater's orifi ce with compressed air or a soft,
dry rag. Do not use fi les, drills, broaches, etc. to clean
the orifi ce hole. Doing so will enlarge the hole, causing
combustion or ignition problems. Replace the orifi ce if it
cannot be cleaned properly.
