Safety Precautions
WARNING
Asphyxiation Hazard
■ Do not use this heater for heating human living
quarters.
■ Do not use in unventilated areas.
■ The flow of combustion and ventilation air must not be
obstructed.
L.B. White Company to determine combustion air
ventilation requirements of the heater.
■ Lack of proper ventilation air will lead to improper
combustion.
■ Proper ventilation air must be provided to support the
combustion air requirements of the heater being used.
■ Improper combustion can lead to carbon monoxide
poisoning leading to serious injur y or death.
Symptoms of carbon monoxide poisoning can include
headaches, dizziness and difficulty in breathing.
■ Refer to the specification section of the heater’s
Owner’s Manual, heater dataplate, or contact the
■ Symptoms of improper combustion affecting livestock
can be disease, lower feed conversion, or death.
Propane gas and natural gas have man-made odorants 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 gas tank or cylinder fuel supply valves,
or the main fuel supply valve located 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.
■ 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 appliance 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 these fuel gases.
■ Learn to recognize the odor of propane gas and 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.
■ 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 has a distinctive odor. Learn to recognize
these odors. (Reference Fuel Gas Odor and Odor Fading
sections above.
■ Even if you are not properly trained in the service and
repair of the heater, ALWAYS be consciously aware of
the odors of propane gas and natural gas.
■ If you have not been properly trained in repair and service
of propane gas then do not attempt to light heater,
perform service or repairs, or make any adjustments to
the heater on the propane gas fuel system.
■ 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!

Installation Instructions
GENERAL
WARNING
Fire or explosion hazard.
Can cause property damage, severe injury or death.
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.
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. For heaters intended for outdoor installation, the
heater is to be installed at least 18 inches above the
ground or to a height that would prevent snow
blockage of heater’s air inlet.
4. The heater may be used either indoors or outdoors.
When the heater is mounted outdoors, use only the
ductwork supplied in the outdoor mounting kit.
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., Inc. if you have any questions.
6. The heater’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.
7. All gas pressure regulators must be installed in strict
accordance with the manufacturer’s safety instructions.
These instructions accompany each regulator.
8. Insure that all accessories that ship within the heater
have been removed from inside of heater and
installed. This per tains to air diver ters, hose,
regulators, etc.
9. 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.
10. 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.
11. Check all connections for gas leaks using approved
gas leak detectors. Gas leak testing is performed as
follows:
WARNING
■

■
■
Fire and Explosion Hazard
Do not use open flame (matches, torches, candles,
etc.) in checking for gas leaks.
Use only approved leak detectors.
Failure to follow this warning can lead to fires or
explosions.
Fires or explosions can lead to property damage,
personal injury or loss of life.
-- 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.
-- Furthermore 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.
-- 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.

the status of the heater. The LED is visible external
of the control enclosure through the viewing window.
A constant light from the LED is an indicator that the
heater is functioning correctly. Any flash pattern by
the LED is indicative that there is a problem in the
operation of the heater. Refer to the troubleshooting
decal on the access panel at the fan motor end of the
heater for assistance in troubleshooting. Only
qualified and properly trained personnel shall service
or repair the heater.
Follow steps 1 - 6 on initial start-up after heater installation
by a qualified gas heater service person. For normal startup, simply turn thermostat above room temperature. The
heater will start.
1.
Open all manual fuel supply valves and check for gas
leaks using approved leak detectors. The gas control
valve on the heater has a manual shut-off feature
incorporated into the valve assembly. Make sure the
indicator on the valve is turned to the “on” position.

On a call for heat, the motor will start up and run for
five (5) seconds. This “pre-purge” is a safety feature
and a normal operational characteristic prior to
ignition taking place. After five (5) seconds, the
igniter will begin to start.
6.
The ignition control will make up to three trials for
ignition. Each trial for ignition will take approximately
ten (10) seconds. The first three trials for ignition will
occur within 40 seconds if ignition is not achieved. A
15 minute “wait period” will then begin after the third
trial for ignition has taken place. After the 15 minute
time span has elapsed, three more trials for ignition
will take place. If ignition is not achieved at this final
trial, the system will “lock out”, and a three flash
pattern will be indicated by the LED.
Shut-Down Instructions
If the heater is to be shut down for cleaning, maintenance or
repair, follow steps 1 - 5. Otherwise, simply turn thermostat
to “off” or “no heat” for standard shut down.

Variable Heat Output
1. Some models of propane (LP) gas or natural gas
heaters have a throttle valve for varying heat output
located between the gas control valve and gas
manifold assemblies. See Fig. 7. THIS IS NOT A
MANUAL GAS SHUT OFF VALVE.
2. The throttle valve can be adjusted to deliver either
minimum heat or maximum heat. When the throttle
valve handle is parallel to the gas flow, the valve is
completely open to deliver maximum heat output.
The throttle valve may be adjusted to minimum heat
output by turning the handle 90° to gas flow or any
position between maximum and minimum settings.

Cleaning Instructions
WARNING
Fire, Burn, and Explosion Hazard
■ This heater contains electrical and mechanical components in the gas management, safety and airflow systems.
■ Such components may become inoperative or fail due to dust, dirt, wear, aging, or the corrosive atmosphere of an
animal confinement building.
■ Periodic cleaning and inspection as well as proper maintenance are essential to avoid serious injury or property
damage.
1. Before cleaning, shut off all gas supply valves and
disconnect electrical supply.
2. The heater should have dir t or dust removed
periodically:
a. Af ter each flock or between building repopulation, give the heater a general cleaning
using compressed air or a soft brush on its
interior and exterior. At this time, dust off the
motor case to prevent the motor from over-heating
and shutting the heater down.
b. At least once a year, give the heater a thorough
cleaning. At this time, remove the fan and motor
assembly and brush or blow off the fan wheel,
giving attention to the individual fan blades.
Additionally, make sure the burner air inlet venturi
ports and the “throat” of the casting are free of
dust accumulation and the area between the heat
chamber top and inside case is also free of dust.
c. When washing with water, observe and obey the
Warning within these Cleaning Instructions. This
same Warning is also supplied on the heater.
WARNING
This heater may be washed only on the external case
assembly provided:
A.
The heater is disconnected from the electrical
supply.
B.
All access panels are securely closed.
C.
Water spray nozzle shall not discharge within 6 feet
of the heater.
D.
The water pressure does not exceed 45 PSIG for 10
seconds on each side of heater.
E.
The heater is not reconnected to electrical supply for
a minimum of 1 hour or until the heater is
thoroughly dry.
Improper cleaning of the heater can cause severe
personal injury or property damage due to water and/or
cleaning solution:
1.
In electrical components, connections and wires
causing electrical shock or component failure.
2.
On gas control components causing corrosion which
can result in gas leaks and fire or explosion from the
leak.
Clean internal components of the heater with a soft, dry
brush or cloth, or compressed air.
Maintenance Instructions
1. Have your gas supplier check all gas piping annually
for leaks or restrictions in gas lines. Also, at this time
have your gas supplier clean out the sediment trap of
any debris that may have accumulated.
2. The heater’s surrounding area shall be kept clear and
free from combustible materials, gasoline, and other
flammable vapors and liquids.
3. 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 appliance to make sure that the regulator is
reliable.
4. Regulators must be periodically inspected to make
sure the regulator vents are not blocked. Debris,
insects, insect nests, snow, or ice on a regulator can
block vents and cause excess pressure at the
appliance.
5. Review all heater markings (ie. warnings, startup/shutdown, electrical wiring, diagrams, etc.) for
legibility. Ensure that none are cut, torn, or otherwise
damaged. Any damaged markings must be replaced
immediately by contacting L.B. White Co., Inc.
Markings are available at no cost.
6. Inspect gas hoses for nicks,cuts, or corroded fittings.
Replace the complete gas hose assembly if defects
are found.
7. Inspect the heater’s electrical connections. Replace
any terminals that are corroded.

Service Instructions
GENERAL
WARNING
Burn Hazard
■ Heater surfaces are 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.
■ All component parts must be replaced if defects are
found.
■ Failure to follow this warning will result in fire or
explosions, causing property damage, injury, or
death.
1. Close the fuel supply valve to the heater and
disconnect the electrical supply before servicing unless
necessary for your service procedure.
2. Clean the heater’s orifice with compressed air or a soft,
dry rag. Do not use files, drills, broaches, etc. to clean
the orifice hole. Doing so will enlarge the hole, causing
combustion or ignition problems. Replace the orifice if
it cannot be cleaned properly.
3. The high limit switch can be tested by disconnecting the
leads at the component, and jumpering the leads
together.:
-- Reconnect the electrical supply and open fuel
supply valves.
-- If the heater lights, the component is defective
and must be replaced.
-- Do not leave the jumper on or operate the heater if
the part is defective. Replace the part immediately.
-- An alternate method for checking the components
is to perform a continuity check.
4. The air proving switch must not be jumpered. If
jumpered, the ignition control will not allow heater
operation. Test the air proving switch for continuity.
If defective, replace the switch.
5. Open the respective case panel for access to burner or
fan related components. Open the control box for
access to the ignition control, and transformer.
6. Disconnect the appropriate electrical leads when
replacing components.
7. For reassembly, reverse the respective ser vice
procedure. Ensure gas connections are tightened
securely.
8. After servicing, start the heater to ensure proper
operation and check for gas leaks.
MOTOR AND FAN WHEEL ASSEMBLY
1. Remove the motor mounting plate screws and lift the
fan and motor assembly from the housing. See Fig. 9.
2. Loosen the square head set screw(s) on the fan
wheel.
NOTES:a.Fan wheel to motor mount plate spacing
must be adjusted to the clearance
specified in the table below before
tightening the fan wheel to the motor
shaft.
b. Make sure that set screw(s) of the fan are
on the flats of motor shaf t when
tightening.
3. Pull the fan wheel from the motor shaft. Use a wheel

AIR PROVING SWITCH
The air proving switch is located on the fan housing at
the motor end of the heater. It must work properly to
allow an ignition cycle. If the air proving switch contacts
are closed before the igntion control starts the fan motor,
or do not close on a call for heat after the fan motor
starts, ignition will not occur. See Fig. 11
FIG. 11
AIR PROVING SWITCH
To service:
-- Remove the two (2) sheet metal screws holding
the switch with bracket to blower housing.
--
Remove the assembly by turning the switch so the
paddle on the switch arm can be pulled through
the oblong hole on side of fan housing.
IGNITER AND FLAME SENSOR ASSEMBLY
■ Refer to Fig. 12 for servicing of the igniter assembly.
■ The igniter/sensor assembly may require cleaning due
to accumulations of dust and dirt over a period of
time, affecting its ability to ignite fuel gas and sense
burner flame. Cleaning will require igniter/sensor
removal.
-- If spark appears to be weak, rub the igniter
electrode with emery cloth or steel wool to remove
any buildup.
■ Ensure the igniter gap is 1/8 - 3/16 in. and the igniter
tip is positioned over the burner port according to the
illustration below.
■ Prior to start up when the heater has not been used
for an extended period of time:
-- Clean the sensor of moisture/dust
-- Ensure the top of the burner casting is free of
corrosion. Remove corrosion with emery cloth or
a wire brush.
- Corrosion prevents the igniter from
sparking to the top of the burner.
-- If the spark appears strong but the heater cycles
off, clean the sensor with emery cloth or steel
wool to remove any build-up. Also remove dust and
dirt from inside the igniter enclosure.

Chamber used for compressing air for ef ficient air
movement.
Igniter/Flame Sensor Assembly
This assembly consists of two components mounted
adjacent on the same bracket.
-- Spark Igniter: Electrical ignition device used on
automatic ignition control systems. Ignites gas by a
spark.
Fan Wheel
Component used in conjunction with the motor and fan
housing to pull the hot air from heater and blow it into room
for heating (also known as a “squirrel cage”).
-- Flame Sensor: Also known as a flame rod or flame
probe, this device works in conjunction with the ignition
module in proving that burner flame has been
established.
Gas Control Valve
A device which consists of a low pressure regulator and
electrical solenoids which are used for the control of gas
flow to the burner assembly. A feature of the control is a
built in gas shut off which is used to isolate the heater from
its gas supply when servicing.
Motor
Electric device used to force preheated air through the
heater and to circulate heat within a certain area. Converts
electrical energy into mechanical energy.
Gas Hose
Flexible connector used to convey gas from supply line in
building to heater.
Regulator
The heart of any gas supply installation. Used to deliver a
working pressure to the appliance under varying conditions
in tank pressure.
Heat Chamber
Metal “fire box” within the appliance that provides an area
where burner flame mixes with combustion air thereby
providing heat.
Thermostat
Electrical device used as an automatic “on/off” switch
which will respond to changes in temperature in a certain
area. Can be wired so contacts in the thermostat open or
close on temperature increase or decrease.
High Limit Switch
Safety device wired into the control system which is used to
break an electrical circuit to the gas control valve in event of
overheat situation.
Throttle Valve
Manually adjustable component used to increase or
decrease the flow of gas to the burner. The throttle valve is
located between the gas control valve and burner assembly.
Transformer
This device is responsible for reducing a higher incoming
voltage (normally 115 V.A.C.) to a lower outgoing voltage.
The lower voltage (24 V.A.C.) is essential to operate the
ignition control module.
