Safety Precautions
Asphyxiation Hazard
■ Do not use this radiant heater for heating human living
quarters.
WARNING
L.B. White Company to determine combustion air
ventilation requirements of the heater.
■ Do not use in unventilated areas.
■ The flow of combustion and ventilation air must not be
obstructed.
■ Proper ventilation must be provided to support the
combustion air requirements of the heater being used.
■ Refer to the specification section of the Owner’s
Manual, heater’s dataplate, or contact the
■ Lack of proper ventilation air will lead to carbon
monoxide poisoning in humans leading to serious
injury or death. Symptoms of carbon monoxide
poisoning can include headaches, dizziness and
difficulty in breathing.
■ Symptoms of improper ventilation affecting livestock
can be disease, lower feed conversion, or death.
FUEL GAS ODOR
Propane gas and natural gas has man-made odorant added specifically for detection of fuel gas leaks.
If a gas leak occurs, you should be able to smell the fuel gas.
THAT’S YOUR SIGNAL TO GO INTO IMMEDIATE ACTION!
■ Do not take any action that could ignite the fuel gas. Do
not operate any electrical switches. Do not pull any
power supply or extension cords. Do not light matches
or any other source of flame. Do not use your
telephone.
■ Get everyone out of the building and away from the area
immediately.
■ Close all propane (LP) gas tank or cylinder fuel supply
valves, or the main fuel supply valve at the meter if you
use natural gas.
■ Propane gas is heavier than air and may settle in low
areas. When you have reason to suspect a propane
leak, keep out of all low areas.
■ Natural gas is lighter than air and can collect around
rafters or ceilings.
■ Use your neighbor’s phone and call your fuel gas
supplier and your fire department. Do not re-enter the
building or area.
■ Stay out of the building and away from the area until
declared safe by the firefighters and your fuel gas
supplier.
■ FINALLY, let the fuel gas service person and the
firefighters check for escaped gas. Have them air out
the building and area before you return. Properly
trained service people must repair the leak, check for
further leakages, and then relight the heater for you.
ODOR FADING -- NO ODOR DETECTED
■ Some people cannot smell well. Some people cannot
smell the odor of the man-made chemical added to
propane or natural gas. You must determine if you
can smell the odorant in this fuel gas.
■ Learn to recognize the odor of propane gas or natural
gas. Local propane gas dealers will be more than
happy to give you a “scratch and sniff” pamphlet. Use it
to become familiar with the fuel gas odor.
■ Smoking can decrease your ability to smell. Being
around an odor for a period of time can affect your
sensitivity to that particular odor. Odors present in
animal confinement buildings can mask fuel gas odor.
■ The odorant in propane gas and natural gas is
colorless and the intensity of its odor can fade under
some circumstances.
■ If there is an underground leak, the movement of gas
through the soil can filter the odorant.
■ Propane gas odor may differ in intensity at different
levels. Since propane gas is heavier than air, there may
be more odor at lower levels.
■ Always be sensitive to the slightest gas odor. If you
continue to detect any gas odor, no matter how small,
treat it as a serious leak. Immediately go into action as
discussed previously.
ATTENTION -- CRITICAL POINTS TO REMEMBER!
■ Propane gas and natural gas has a distinctive odor.
Learn to recognize this odors. (Reference “Fuel Gas
Odor” and “Odor Fading” sections above.
■
If you have not been properly trained in repair and service
of propane gas and natural gas fueled heaters, then do
not attempt to light the heater, perform service or repairs,
or make any adjustments to the heater on a propane gas
or fuel system.
6
■ Even if you are not properly trained in the service and
repair of radiant heaters, ALWAYS be consciously aware
of the odors of propane gas and natural gas.
■ A periodic “sniff test” around the heater or at the
heater’s joints; i.e. hose, connections, etc., is a good
safety practice under any conditions. If you smell even
a small amount of gas, CONTACT YOUR FUEL GAS
SUPPLIER IMMEDIATELY. DO NOT WAIT!

application of pipe compound before further
tightening.
-- 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.
12. Install a sediment trap 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.
13. Any heater connected to a piping system must have
an accessible, approved manual shut off valve
installed within six feet (6 ft.) of the heater it serves.
14. Install the proper gas supply line to assure proper
functioning of the heaters. Consult your fuel gas
supplier, or the L.B. White Co., Inc. for proper line
sizing and installation.
15. Light according to instructions on heater or within
Owner’s Manual.
16. The heater is designed for L.P. vapor withdrawal or
natural gas only. Do not use this heater in a
propane liquid withdrawal system. Do not permit
propane in liquid form to enter the heater at any
time.
17. The corrosive atmosphere present in animal
confinement buildings can cause component failure
or heater malfunction. The heater should be
periodically inspected and cleaned in accordance
with the Maintenance and Cleaning Instructions in
this manual. Make sure that livestock is protected
by a back up alarm system that limits high and low
temperatures and also activates appropriate alarms.
18. Take time to understand how to operate and
maintain the heater using the owner’s manual.
Make sure you know how to shut off the gas supply
to the building and to the heater. Contact your gas
supplier if you have any questions.
19. Any defects found in performing any of the service
procedures must be eliminated and defective parts
replaced immediately. Retest the heater before
placing it back into service.
20. Do not exceed input rating stamped on the
dataplate of the heater. Do not exceed the burner
manifold pressure stated on the dataplate. Do not
use an orifice size different than specified for the
specific input rating of this heater, fuel type
configuration and altitude.

INITIAL SETUP
1. Plan the installation. Determine location for the
heater to optimize its heat pattern, keeping in mind
cooler regions in the house (end walls, and curtains)
and clearances to combustibles.
2. Hang the burner box. See Fig. 5. Maintain clearances
to combustibles as shown in Fig. 1.
3. From the burner box chain, measure the distances
shown in Fig. 6. Aligning to the center of the burner
box discharge, hang chains at these points, using
open eye hooks.
