SAFETY INFORMATION (CONT.)

WARNING RISK OF INDOOR AIR POLLUTION!

The products described in this manual are natural gas direct-fired, forced air heaters. Natural gas forced air heaters are primarily intended for use for temporary heating of buildings under construction, alteration or repair. Direct-fired means that all of the combustion products of the heater enter the heated space. This appliance is rated at 98% combustion efficiency, but does produce small amounts of carbon monoxide.

DANGER CARBON MONOXIDE POISONING MAY LEAD TO DEATH!

Carbon monoxide is toxic. Humans can tolerate only small amounts of carbon monoxide and so precautions should be taken to provide proper ventilation. Failure to provide proper ventilation in accordance with the instructions in this manual can result in death.

People with breathing problems should consult a physician before using this heater. Early signs of carbon monoxide poisoning resemble the flu. Symptoms of improper ventilation / carbon monoxide poisoning are:

Headache · Dizziness · Nausea · Dry Mouth Sore Throat · Burning of Nose and Eyes

If you experience any of these symptoms: GET FRESH AIR AT ONCE! Have your heater serviced and check for proper ventilation. Some people are more affected by carbon monoxide than others. These include: pregnant women, those with heart or lung problems, anemia or those under the influence of alcohol or at high altitudes.

FOR OUTDOOR USE. INDOOR USE PERMITTED ONLY FOR: The temporary heating of adequately ventilated buildings or structures under construction, alteration or repair! Provide at least a three square foot (2,800 sq cm) opening of outside air for every 100,000 Btu / Hr heater rating. Refer to "Ventilation" on page 9 for further instructions.

• DO NOT attempt to light the heater.
• Extinguish any open flame.
• Shut off gas to heater.
• If odor continues, contact your local gas supplier or fire department.
• DO NOT touch or use any electric switch or any electric device that can cause a spark.
• Immediately call your gas supplier from a neighbors phone. Follow the gas suppliers instructions.
• If you can not reach your gas supplier, call the fire department.
  Service must be done by a qualified service agency.
