DO NOT allow anyone who has not read these instructions to assemble, light, adjust or operate this heater. B. LP‑Gas IS HIGHLY FLAMMABLE. In the event of a leak, LP-Gas will accumulate and the possibility of a re is present. LP-Gas is scented and its strong odor is readily detectable. Never strike a match, bring any ame or create an electric spark in an enclosure when you smell LP-Gas. Ventilate the area thoroughly, move the heater outside, and correct the source of the leak before attempting to light any appliance. C. Always operate the heater with the LP-Gas cylinder in an upright position on a level non-combustible surface. NEVER PLACE THE CYLINDER ON ITS SIDE WHEN OPERATING THE HEATER. D. DO NOT attempt to operate the heater with any gas other than that indicated on the heater nameplate.

• 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 connement buildings can mask fuel gas odor.

WARNING: RISK OF ASPHYXIATION

• Do not use in unventilated areas.

• The ow 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 specication section of the heater’s manual, heater data-plate, 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. Symptom of carbon monoxide poisoning can include headaches, dizziness and difculty in breathing. WARNING Never use a fork lift truck type cylinder.

• 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 lter out 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.

• 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.
