FUEL GAS ODOR
LP 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. Since Propane (LP) is heavier than air you should
smell for the gas odor low to the floor. ANY GAS ODOR
IS 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 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.
• 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 any leaks, 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 (LP) or natural gas. You must determine if you
can smell the odorant in these fuel gases.
• Learn to recognize the odor of propane (LP) gas and natural
gas. Local propane (LP) 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
ODOR FADE WARNING
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.
• 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 manual, heater dataplate, or contact the Factory 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. Symptom of carbon
monoxide poisoning can include headaches dizziness and difficulty in breathing.
animal confinement buildings can mask fuel gas odor.
• The odorant in propane (LP) 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 (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.
• 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 (LP) 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 (LP) gas and natural gas.
• 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.
• 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!
