Instructions
BEFORE EACH USE: (Manual and Spark
Ignition)
■
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 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
installation, 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
excessive 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 com-
ponents, loose screws or bolts, etc. Replace
any suspect components immediately.
■
For safety as well as for optimum perfor-
mance of the heater, it is necessary to keep
the inside and the outside of the heater free
of dust, dirt, or any combustible material.
■
Check the three burner plate nuts to ensure
all are snugged securely.
■
Review all heater labels at the time of main-
tenance for legibility. Make sure none are
cut, torn, or otherwise damaged. Any dam-
aged labels must be replaced immediately
by contacting the L.B. White Co., Inc.
ANNUALLY:
■
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.
