Asphyxiation Hazard
Do not use this heater for heating human living ■ Improper combustion can lead to carbon monoxide
quarters, garages, workshops, or other such confined
poisoning leading to serious injury or death. Symptoms
spaces.
of carbon monoxide poisoning can include headaches,
dizziness and difficulty in breathing.
Do not use in unventilated areas.
■ Proper ventilation air for combustion must be provided
The flow of combustion and ventilation air must not be
in accordance with OSHA 29 CFR 1926.154,
obstructed.
Temporary Heating Devices, ANSI A10.10, Safety
Requirements for Temporary and Portable Space
Proper ventilation air must be provided to support the
Heating Devices, or the Natural Gas and Propane
combustion air requirements of the heater being used.
Installation Code, CAN/CSA B149.1 as appropriate.
■ Lack of proper ventilation air will lead to improper
combustion.
FUEL GAS ODOR
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!

PROPANE GAS SUPPLY SIZING
The vaporization of propane is affected by several factors:
the surface area of the container, the liquid level of
propane, temperature surrounding the container, and the
relative humidity. All of these factors are specific to a site.
Therefore, a degree of experience and judgement is
required to select the proper propane supply.
Although experience is the best guide, the following
recommendations can be used as a starting point. The
table is based on experience in northern climates where
cold weather and high humidity are prevalent in the winter.
If more or less favorable conditions prevail at a specific
site, adjustments can be made on the basis of experience.

WARNING
Fire, Burn, and Explosion Hazard
■ This heater contains electrical and mechanical components in the gas management, and safety systems.
■ Such components may become inoperative or fail due to dust, dirt, wear and aging.
■ 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. Before each use give the heater a general
cleaning using compressed air or a soft brush or
dry rag on its case and internal components. At
this time, dust off the motor case to prevent the
motor from over-heating.
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 blade
assembly. Additionally, make sure the burner air
inlet venturi ports and the casting are free of dust
accumulation.
WARNING
Do not use a pressure washer, water, or liquid cleaning
solution on any gas controls. Use of a pressure washer,
water, or liquid cleaning solution on the control
components can cause severe personal injur y or
property damage due to water and/or liquids:
■ In electrical components, and wires causing electrical
shock or equipment failure.
■ On gas control valves causing corrosion which can
result in gas leaks and fire or explosion from the leak.
Clean all components of the heater with pressurized air,
a dry brush, or a dry cloth.
Maintenance Instructions
1. The area surrounding the heater shall be kept clear
and free from combustible materials, gasoline, and
other flammable vapors and liquids.
2. Have your gas supplier check all gas piping annually
for leaks or restrictions in gas lines.
3. 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 heater.
4. 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.
5. Check all wiring, associated terminals, and electrical
components within the heater for corrosion, frayed or
cut insulation, tight connections, etc. Repair or
replace as necessary.
6. Review all heater markings (i.e. wiring diagram,
warnings, start-up, shut-down, troubleshooting, etc.)
at the time of maintenance for legibility. Make sure
none are cut, torn, or otherwise damaged. Any
damaged markings must be replaced immediately by
contacting the L.B. White Co., Inc. Dataplates, startup and shut-down instructions and warnings are
available at no cost. A nominal charge will be applied

Heater Component Function
Air Proving Switch
Safety device used to insure that the proper air flow is being
achieved before the gas valve is opened.
Burner
Cast iron component used to channel gas and provide an
area at which the fuel may ignite.
Burner Orifice
Brass metering device used to feed gas to burner at a
specific rate.
Direct Spark Ignition Control Module
Electronic printed circuit board which sends and receives
voltages to various controls in an automatic ignition system.
An important safety feature of the control board is that it will
shut down the entire heater, thereby stopping the flow of
fuel gas if burner flame goes out.
Fan Housing
Chamber used for delivering air for efficient air movement.
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).
Gas Control Valve
Electrical device consisting of a low pressure regulator and
electrical solenoids used for the control of gas flow to the
burner assembly. A feature of the control valve is a built-in
gas shut off which may be used to isolate the heater from its
gas supply when servicing.
Gas Hose
Flexible connector used to convey gas from supply line in
building to heater.
Gas Selector Valve
Allows easy gas conversion depending on gas being
supplied at job site. Eliminates the need for changeout of
the burner orifice .
Heat Chamber
Metal fire box within the heater that provides an area where
burner flame mixes with combustion air, thereby providing
heat.
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.
Igniter
Ignition device used on automatic direct spark ignition
control systems. Ignites gas by spark.
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.
Regulator
Mechanical device used in gas distribution systems to
reduce a higher inlet pressure to a preset lower pressure.
The regulator is responsible to supply a steady outlet
pressure to the heater(s) despite changes in inlet pressure,
heater demand and weather conditions.
Selector Switch
Electrical device which is used to allow the end user to use
the heater in either a heating or ventilation application.
Status Light
A green light emitting diode (L.E.D.) wired into the electrical
circuit. Provides an easily recognizable indication of heater
operation.
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.
Transformer
Electrical control used to accept line power supply primary
voltage and reduce it to lower secondary voltage to operate
certain control systems.
