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/CGA

2.14. 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/NFPA 70, or Canadian Electrical Code, part 1.

• Electrical grounding instructions — This appliance is equipped with a three-prong (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 1.5-squarefoot opening of fresh, outside air.

• Approved by the New York City Fire Department under Certificate of Approval #4953. To be used only at construction site with applicable New York City codes, regulations, rules, directives, permits, etc.

• This product has been approved for use in the Commonwealth of Massachusetts.

• 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 may 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: 6 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.

• T o 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.

UNPACKING

1. Remove all packing items applied to

heater for shipment. Keep plastic cover caps (attached to inlet connector and hose/regulator assembly) for storage.

2. Remove all items from carton.

3. Check all items for shipping damage.

If heater is damaged, promptly inform dealer where you bought heater.

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. See Chapter 5 of the Standard for Storage and Handling of

Liqueﬁed Petroleum Gas, ANSI/NFPA 58 and/or CAN/CGA B149.2. Your local library

or ﬁre department will have this booklet. The amount of propane gas ready for use

from propane tanks varies. Two factors decide this amount:

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

2. The temperature of tank(s)

This heater is designed to operate with a minimum 20-pound propane tank. You may need two or more tanks or one larger tank in colder weather. Use a 100-pound tank for longer operation or in very cold weather. Less gas is vaporized at lower temperatures. Your local propane gas dealer will help you select the proper supply system. The minimum surrounding air temperature rating for each heater is -20°F (-29°C).

THEORY OF OPERATION

THE FUEL SYSTEM

The hose/regulator assembly attaches to the propane gas supply. This provides fuel to the heater.

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 piezo ignitor lights the burner.

THE AUTOMATIC CONTROL SYSTEM

This system causes the heater to shut down if the ﬂame goes out.
