■ 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.

■ 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 a n y ot h er sou rce of f lam e . D o n o t us e you r
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 located at the
meter if you use natural gas.

■ Propane (LP) 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.

AAsspphhyyxxiiaattiioonn HHaazzaarrdd

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.

■ 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.

FFIINNAA LLLLYY,,

■

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.

■ Learn to recognize the odor of propane (LP) gas and

natural gas. Local propane (LP) gas dealers will be
more t h a n hap py 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.

ATTENTION -- CRITICAL POINTS TO REMEMBER!

■ Propane (LP) 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 (LP) gas then do not attempt to light heater,
perform service or repairs, or make any adjustments to
the heater on the propane (LP) gas fuel system.

■ If there is an underground leak, the movement of gas

through the soil can filter the odorant.

■ Propane (LP) gas odor may differ in intensity at different

levels. Since propane (LP) gas is heavier than air, there
may be more odor at lower levels.

■

continue to detect any gas odor, no matter how small,
treat it as a serious leak. Immediately go into action as
discussed previously.

■ Even if you are not properly trained in the service and

repair of the heater, ALWAYS be consciously aware of
the odors of propane (LP) gas and natural gas.

■ A periodic s n if f test aroun d 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 FUE L GAS
SUPPLIER IMMEDIATELY. DO NOT WAIT!
