Motor Characteristics
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.
■ 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.
5
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 then do not attempt to light heater,
perform service or repairs, or make any adjustments to
the heater on the propane gas fuel system.
■ 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.
■ 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!
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.
■ 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.

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.
Recommended Gas Supply
Propane Supply Tank: Heater(s)/Container(s):
500 gallon 1 heater per tank
1,000 gallon 2 heaters per tank
If more than one gas supply container is used per heater,
the containers must be manifolded together to allow vapor
withdrawal simultaneously from multiple containers.
Manifold system shall be in accordance with NFPA 58.
