1. Read all safety precautions and follow L. B. White
recommendations when installing this heater. If
during the installation or relocating of heater, you
suspect that a part is damaged or defective, call a
qualified service agency for repair or replacement.
2. Make sure the heater is properly positioned before
use and is hung level. Observe and obey all minimum
safe distances of the heater to the nearest
combustible materials. Minimum safe distances are
given on the heater nameplate and on page 4 of this
manual.
3. The unit’s gas regulator (with pressure relief valve)
should be installed outside of building. Any regulators
inside the buildings must be properly vented to the
outside. Local, state and national codes always apply
to regulator installation. Natural gas regulators with
vent limiting device may be mounted indoors without
venting to outdoors.
4. Insure that all accessories that ship within the heater
have been removed from inside of heater and
installed. This pertains to air diverters, hose,
regulators, etc.
5. Make certain that a sediment trap is installed at the
gas valve inlet to prevent foreign materials (pipe
compound, pipe chips and scale) from entering the
gas valve. Debris blown into the gas valve may cause
that valve to malfunction resulting in a serious gas
leak that could result in a possible fire or explosion
causing loss of products, building or even life. A
properly installed sediment trap will keep foreign
materials from entering the gas valve and protect the
safe functioning of that important safety component.
6. Any heater connected to a piping system must have an
accessible, approved manual shut off valve installed
within 1.83 meters of the heater it serves.
7. Check all connections for gas leaks using approved
gas leak detectors. Gas leak testing is performed as
follows: Check all pipe connections, hose
connections, fittings and adapters upstream of the
gas control with approved gas leak detectors. In the
event a gas leak is detected, check the components
involved for cleanliness and proper application of pipe
compound before further tightening. Further tighten
the gas connections as necessary to stop the leak.
After all connections are checked and any leaks are
stopped, turn on the main burner. Stand clear while
the main burner ignites to prevent injury caused from
hidden leaks that could cause flashback. With the
main burner in operation, check all connections, hose
connections, fittings and joints as well as the gas
control valve inlet and outlet connections with
approved gas leak detectors. If a leak is detected,
check the components involved for cleanliness in the
thread areas and proper application of pipe
compound before further tightening. Further tighten
the gas connection as necessary to stop the leak. If
necessary, replace the parts or components involved
if the leak cannot be stopped. Ensure all gas leaks
have been identified and repaired before proceeding.
8. A qualified service agency must check for proper
operating gas pressure upon installation of the heater.
9. Light according to instructions on heater or within
owner's manual.
10. It is extremely important to use the proper size and
type of gas supply line to assure proper functioning of
the heater. Contact your fuel gas supplier for proper
line sizing and installation.
11. Make sure the heater has the proper gas regulator for
the application. A regulator must be connected to the
gas supply so that gas pressure at the inlet to the gas
valve is regulated within the range specified on the
dataplate at all times. Contact your gas supplier, or
the L.B. White Co., Inc. if you have any questions.
12. This heater can be configured for use with either L.P.
gas vapor withdrawal or natural gas. Consult the
dataplate, located on interior of the burner end or
motor end door, for the gas configuration of the
specific heater. Do not use the heater in an L.P. gas
liquid withdrawal system or application. If you are in
doubt, contact the L.B. White Co., Inc.

1. Disconnect power supply before wiring to prevent
electrical shock or equipment damage.
2. To avoid dangerous accumulation of fuel gas, turn
off gas supply at the appliance service valve before
starting installation, and perform gas leak test after
completion of installation.
3. Do not force the gas control knob. Use only your
hand to turn the gas control knob. Never use any
tools. If the knob will not operate by hand, the
control should be replaced by a qualified service
technician. Force or attempted repair may result in
fire or explosion.
