9. The hose assembly should be visually inspected
on an annual basis. If it is evident there is exces-
sive abrasion or wear, or if the hose is cut, it must
be replaced prior to the heater being put into
operation. The hose assembly shall be protected
from animals, building materials, and contact with
hot surfaces during use. The hose assembly shall
be specified by the manufacturer. See parts list.
10. Check for gas leaks and proper function upon
heater installation, before building repopulation
or when relocating.
11. This heater should be inspected for proper
operation by a qualified service person before
building repopulation and at least annually.
12. Always turn off the gas supply to the heater if the
heater is not going to be used in the heating of
livestock.
13. This heater is wired with a ground connection for
your protection against electrical shock hazard. It
may or may not be equipped with a three-prong
(grounding) plug. Regardless of heater model,
the heater must be connected directly to a
properly wired and grounded electrical supply.
Failure to use a properly grounded electrical
supply can result in electrical shock, personal
injury, or death.
14. Direct ignition heaters will make up to three trials
for ignition. If ignition is not achieved, the control
system will lock out the gas control valve. If gas
is smelled after system lock out has occurred,
immediately close all fuel supply valves. Do not
relight until you are sure that all gas that may
have accumulated has cleared away. In any
event, do not relight for at least 5 minutes.
15. In a hanging type installation, rigid pipe or
copper tubing coupled directly to the heater may
cause gas leaks during movement, and therefore
must not be used. Use only gas hose assemblies
that are rated and approved for L.P. gas and
natural gas in a hanging type of installation.
16. Installations not using the gas hose supplied with
this appliance must connect dimensionally using
American National Standard Wrought Steel and
Wrought Iron Pipe B36/10-1970. (Aluminum
piping or tubing shall not be used.) Copper tub-
ing when used for conveying natural gas, shall
be internally tinned or equivalently treated to
resist sulphur.

WARNING
Burn Hazard
Can cause property damage, severe injury or death.
1. Disconnect the 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.
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 mini-
mum 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 heater may be installed indoors or outdoors.
When the heater is installed outdoors, use only
the ductwork supplied in the outdoor mounting kit.
Outdoor mounting kit part numbers:
AD/AW060: 500-09810
AD/AW100: 500-09811
AD/AW250: 500-24097
AW325: 500-27098
4. For heaters intended for outdoor installation, the
heater is to be installed at least 24 inches above
the ground or to a height that would prevent snow
blockage of heater’s air inlet.
5. The heater must have the proper gas regulator
installed 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.,
LLC. if you have any questions.
