SAFETY

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 heateris designed for use as a construction heater in accordance with ANSI Z83.7CGA2.14. (Check with your local fire safety authority if you have questions about heater use.) 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 this heater. Check with your local fire safety authority if you have questions about heater use.
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 can fade. Propane gas may be present even though no odor exists.
Carbon Monoxide Poisoning: Early signs of carbon monoxide poisoning resemble the flu with headache, 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 the heater serviced.
IMPORTANT SAFETY INFORMATION

1. Install and use the 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 Propane Gas Installation Code, CAN/CGA B149.2. This instructs on the safe storage and handling of propane gases.

THEORY OF OPERATION

The Fuel System: The hose/regulator assembly attaches to the propane gas supply. The propane gas moves through the automatic control valve and out the nozzle.
The Ignition System: The spark transformer and spark plug light the main burner.
The Safety Control System: This system causes the heater to shut down if the flame goes out.
NOTE: Some parts are located differently on some heater models.

PROPANE SUPPLY

Propane gas and propane tank(s) are to be furnished by the user.
Use this heater only with a propane vapor withdrawal supply system. The installer must conform with local codes or, in absence of local codes, with the Standard for the Storage and Handling of Liquefied Petroleum Gases, ANSI/NFPA 58 and Propane Gas Installation Code, CAN/CGA B149.1.
The amount of propane gas ready for use from propane tanks varies. Two factors decide this amount:

1. The amount of propane gas in the tank(s)
2. The temperature of the tank(s)

The chart below shows the number of 100 Ib (45 kg) tanks needed to run this heater.
