L.B. White 100 Tradesman Portable Forced Air - Manual (Page 6)

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.
■ 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.
WARNING
■ 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.
■ Proper ventilation air must be provided to support the
combustion air requirements of the heater being used.
■ Refer to the specification section of the heater’s
Owner’s Manual, heater dataplate, or contact the L.B.
White Company to determine combustion air ventilation
requirements of the heater.
■ Lack of proper ventilation air will lead to improper
combustion.
■ Improper combustion can lead to carbon monoxide
poisoning leading to serious injury or death. Symptoms
of carbon monoxide poisoning can include headaches,
dizziness and difficulty in breathing.
Asphyxiation Hazard
■ Some people cannot smell well. Some people cannot
smell the odor of the man-made chemical added to
propane. You must determine if you can smell the
odorant in these fuel gases.
■ Learn to recognize the odor of propane 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 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.
Safety Precautions
FUEL GAS ODOR
ODOR FADING -- NO ODOR DETECTED
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.
■ If you have not been properly trained in repair and service
of propane gas fueled heaters, then do not attempt to
light heater, perform service or repairs, or make any
adjustments to the heater on propane gas.
■ 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.
■ 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! 5
