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 data plate, or contact the factory
to determine combustion air ventilation
requirements of the heater.
• Lack of proper ventilation air will lead to
improper combustion.
• I mproper 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.
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 disconnect 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 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 property 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!
