children must observe clearances to avoid burns
or clothing ignition.

• Check the heater thoroughly for damage. DO
NOT operate a damaged heater.

• The heater should be inspected before each use,
and at least annually by a qualified service
person.

• Do Not Modify the heater or operate a heater,
which has been modified from its original
condition.

• Do Not operate a heater that is not fully
assembled.

• Use only with propane gas.

make sure that there is ample fresh air
ventilation. DO NOT use in buildings, garages,
or other enclosed spaces.

• If at any time gas odor is detected,
IMMEDIATELY DISCONTINUE operation until
the source of gas has been located and
corrected. See Fuel Safety Precautions for
more details about smelling odors.

• Install the heater such that it is not directly
exposed to water spray, rain and or dripping
water or wind.

Fuel Safety Precautions

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,

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 the
leak, check for further leakages, and them 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.

heater data plate, or contact the ENERCO /
MR. HEATER 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

.

 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 (I-P) 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.
