must ensure that precautions are taken to protect the appliance

from physical damage.

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.

Operating Instructions and Owner’s ManualPortable Propane Cabinet Heater
