1. GENERAL INFORMATION
A. The Mr. Heater MH12C and the MH12CS are high pressure
propane appliances and are designed to be connected to a 14.1
or 16.4 ounce disposable propane cylinder. Every unit is tested
during manufacturing and shipped fully assembled except for the
wire stand.
B. These heaters are equipped with an automatic Safety Shutoff
Valve. The gas flow will automatically stop if the heater fails to
operate for any reason.
C. Maximum safety and convenience have been built into the Hi-
Med-Lo-Off Control Valve/Regulator. The following table lists the
approximate BTU’s consumed and the operating hours you can
reasonably expect from bulk propane cylinders.
D. Model MH12CS is equipped with an igniter for convenient heater
lite-off.
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 f
uel gas supplier
-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.
•
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 con¯nement
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 aw
are 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!
