WARNING ICON G 001

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.

WARNINGS

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 Na-

tional Electric Code, ANSI/NFPA 70 or Canadian Electric Code, Part 1.

• Electrical grounding instructions — This appliance is equipped with a threeprong (grounding) plug for your protection against shock hazard and should be plugged directly into a properly grounded three-prong receptacle.

• Use only a three-prong, grounded extension cord.

• Use only the hose and factory preset regulator provided with the heater.

• Use only propane gas set up for vapor withdrawal.

• Provide adequate ventilation. Before using heater, provide at least a four and one

half (4.5)-square-foot opening of fresh, outside air for each 100,000 Btu/Hr of rating. This heater produces carbon monoxide, which is listed by the State of California as a reproductive toxin under Proposition 65.

• For indoor use only. Do not use heater outdoors.

• Do not use heater in occupied dwellings or in living or sleeping quarters.

• Do not use heater below ground level. Propane gas is heavier than air. If a leak

occurs, propane gas will sink to the lowest possible level.

• Keep appliance area clear and free from combustible materials, gasoline, paint thinner, and other flammable vapors and liquids. Do not use heater in areas with high dust content.

• Minimum heater clearances from combustibles: Outlet: 8 Ft. Sides: 2 Ft. Top: 6 Ft. Rear: 2 Ft.

• Keep heater at least six feet from propane tank(s). Do not point heater at propane tank(s) within 20 feet.

• Keep propane tank(s) below 100° F.

• Check heater for damage before each use. Do not use a damaged heater.

• Check hose before each use of heater. If highly worn or cut, replace before

using heater.

• Locate heater on stable and level surface if heater is hot or operating.

• Not intended for use on finished floors.

• Never block air inlet (rear) or air outlet (front) of heater.

• Keep heater away from strong drafts, water spray, rain, or dripping water.

• Do not leave heater unattended.

• Keep children and animals away from heater.

• Never move, handle, or service a hot, operating, or plugged-in heater. Severe

burns may result. Wait 20 minutes after turning heater off.

• To prevent injury, wear gloves when handling heater.

• Never attach duct work to heater.

• Do not alter heater. Keep heater in its original state.

• Do not use heater if altered.

• Turn off propane supply and unplug heater when not in use.

• Use only original replacement parts. This heater must use design-specific

parts. Do not substitute or use generic parts. Improper replacement parts could cause serious or fatal injuries.

Air For Combustion And Heating

Fuel

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.
