NEVER LEAVE THE HEATER UNATTENDED WHILE BURNING! NEVER LEAVE THE HEATER UNATTENDED WHILE BURNING! NEVER LEAVE THE HEATER UNATTENDED WHILE BURNING!
WARNING
Asphyxiation Hazard
• 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. Symptoms of carbon monoxide poisoning can
include headaches, dizziness and difficulty in breathing.
Fuel Gas Odour
Propane gas(G31) and butane/propane mixture (G30+G31) gases have man-made
odourants added specifically for detection of fuel gas leaks. If a gas leak occurs
you should be able to smell the fuel gas. Since Propane (G31) is heavier than air
you should smell for the gas odour low to the floor. ANY GAS Odour 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
gas (G31) tank or cylinder fuel supply valves, or the main fuel supply valve located at the
meter if you use natural gas.
• Propane gas (G31) 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 a telephone remote from the area of the leak 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.
Odour Fading - No Odour Detected
• Some people cannot smell well. Some people cannot smell the odour of the man-
made chemical added to propane gas (G31). You must determine if you can smell the
odourant in these fuel gases.
• Learn to recognize the odour of propane gas (G31).
• Smoking can decrease your ability to smell. Being around an odour for a period of time
can affect your sensitivity to that particular odour. Odours present in animal confinement
buildings can mask fuel gas odour.
• The odourant in propane gas (G31) is colorless and the intensity of its odour
can fade under some circumstances. If there is an underground leak, the movement
of gas through the soil can filter the odourant.
• Propane gas (G31) odour may differ in intensity at different levels. Since Propane gas
(G31) is heavier than air, there may be more odour at lower levels.
• Always be sensitive to the slightest gas odour. If you continue to detect any gas
odour, no matter how small, treat it as a serious leak. Immediately go into action as
discussed previously.
ATTENTION - Critical Points to Remember!
• Propane gas (G31) or Butane/Propane mixture (G30+G31) has a distinctive odour.
Learn to recognize these odours. (Reference Fuel Gas Odour and Odour Fading
sections on this same page)
• Even if you are not properly trained in the service and repair of the heater, ALWAYS be
consciously aware of the odours of propane gas(G31) and natural gas.
• If you have not been properly trained in repair and service of propane gas(G31) or
Butane/Propane mixture(G30+G31) then do not attempt to light heater, perform service
or repairs, or make any adjustments to the heater on the propane (G31) or Butane/
Propane mixture(G30+G31) 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!
