SAFETY INFORMATION
WARNINGS
WARNING: FIRE, BURN, IN­HALATION, AND EXPLOSION HAZARD. KEEP SOLID COMBUS­TIBLES, SUCH AS BUILDING MA­TERIALS, PAPER OR CARD­BOARD, A SAFE DISTANCE AWAY FROM THE HEATER AS RECOMMENDED BY THE IN­STRUCTIONS. NEVER USE THE HEATER IN SPACES WHICH DO OR MAY CONTAIN VOLATILE OR AIRBORNE COMBUSTIBLES, OR PRODUCTS SUCH AS GASO­LINE, SOLVENTS, PAINT THIN­NER, DUST PARTICLES OR UN­KNOWN CHEMICALS.
WARNING: NOT FOR HOME OR RECREATIONAL VEHICLE USE.
The heater is designed for use as a construc­tion heater in accordance with ANSI Z83.7•CGA2.14. Other standards govern the use of fuel gases and heating products for specific uses. Your local authority can advise you about these. The primary pur­pose of construction heaters is to provide temporary heating of buildings under con­struction, alteration or repair. Properly used, the heater provides safe economical heat­ing. Products of combustion are vented into the area being heated.
We cannot foresee every use which may be made of our heaters. Check with your local
fire safety authority if you have questions about heater use.
Other standards govern the use of fuel gases and heat producing products for specific uses. Your local authorities can advise you about these.
Carbon Monoxide Poisoning: Some people are more affected by carbon monox­ide than others. Early signs of carbon mon­oxide poisoning resemble the flu, with head­aches, dizziness, and/or nausea. If you have these signs, the heater may not be working properly. Get fresh air at once! Check for proper ventilation and have heater serviced.
Propane Gas: Propane gas is odorless. An odor-making agent is added to propane gas. The odor helps you detect a propane gas leak. However, the odor added to propane gas may fade. Propane gas may be present even though no odor exists.
Make certain you read and understand all warnings. Keep this manual for reference. It is your guide to safe and proper operation of this heater.
• Install and use heater with care. Fol­low all local ordinances and codes. In the absence of local ordinances and codes, refer to the Standard for
Storage and Handling of Liquefied Petroleum Gas, ANSI/NFPA 58 and the Natural Gas Installation Code, CAN/CGA B149.2. This instructs on
the safe storage and handling of pro­pane gases.
• Use only the electrical voltage and frequency specified on model plate.
• The electrical connections and grounding of the heater shall follow the National Electric Code, ANSI/ NFP A 70 or Canadian Electric Code, Part 1.

THEORY OF OPERATION
The Fuel System: The hose/regulator assembly attaches to the propane gas sup­ply. The propane gas moves through the solenoid valve and out the nozzle.
The Air System: The motor turns the fan. The fan pushes air into and around the combustion chamber. This air is heated and provides a stream of clean, hot air.
The Ignition System: The direct spark ignitor (DSI) sends voltage to the ignitor. The ignitor ignites the fuel and air mixture.
The Safety Control System: This sys­tem causes the heater to shut down if the flame goes out. The motor will continue to run, but no heat is produced.
