WARNING: RISK OF INDOOR AIR POLLUTION!

The products described in this manual are propane direct-fired, forced air heaters. Propane-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. 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 by the instructions in this manual can result in death.

DANGER: CARBON MONOXIDE POISONING MAY LEAD TO 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 INDOOR USE ONLY:
Adequate ventilation shall be provided by OSHA 29 CFR 1926.154, Safety Requirements for Temporary and Portable Space Heating Devices and Equipment, ANSI A10.10, ANSI Z223.1/NFPA 54 Liquefied Petroleum Gas Code, NFPA 58 or the Natural Gas and Propane Installation Code, CAN B149.1 as appropriate.

DANGER: PROPANE IS AN EXPLOSIVE GAS.
WHAT TO DO IF THE SMELL OF GAS IS PRESENT:

• DO NOT attempt to light the heater.
• Extinguish any open flame.
• Shut off the gas to the heater.

Operation

Propane Supply / Information: Propane (LP)
This heater is not supplied with a propane cylinder. Use only an approved propane cylinder.

LP Characteristics

• Flammable, explosive under pressure, heavier than air, and pools in low areas.
• In its natural state, propane has no odor, but for your safety, an odor that smells like rotten cabbage has been added.
• Contact of propane (LP) gas with the skin can cause freeze burns.
• The heater is manufactured for use with propane gas only. DO NOT attempt to convert to any other gas. Such modifications are dangerous and will void the warranty.
• When hthe eater is not in use, the LP Cylinder must be turned OFF.
• Be sure that the LP Cylinder is located on a level and stable surface.
• DO NOT use this heater in a basement or below ground level. Propane is heavier than air and will always seek the lowest level. If you suspect a leak, shut off the valve at the LP Cylinder immediately.

The Propane (LP) cylinder must also be equipped with the following:

• A collar to protect the gas valve.
• A shut-off valve terminating an LP cylinder valve outlet as specified in the American National Standard for Compressed Gas Cylinder Valve Outlets and Inlets Connections.
• A safety relief valve having direct communications with the vapor space of the LP cylinder.
• The heater must operate on vapor withdrawal from the operating cylinder.
• Always keep the LP cylinder fastened and upright.

CAUTION: Propane is safe to use when properly handled. Careless handling of the LP cylinder could result in a fire and or an explosion.

• Avoid tipping the LP cylinder on its side when connected to a regulator, since this may cause damage to the diaphragm in the regulator.
• Handle valves with care.
• Never connect an unregulated LP cylinder to a construction heater.
• DO NOT subject the LP cylinder to excessive heat.
• Tightly close the gas shutoff valve on the LP cylinder after each use.
• All fittings must be protected when disconnected from the LP cylinder.
• Never store an LP cylinder inside a building or in the vicinity of a gas-burning appliance.

CAUTION: The disconnected tank must never be stored in a building, garage, or any other enclosed area.

Pre-Lighting Instructions: Connecting the LP Cylinder
ALL NEW LP CYLINDERS MUST BE PURGED BEFORE THE FIRST FILLING.
