SAFETY INFORMATION

WARNINGS

WARNING: This product contains and/or generates chemicals known to the State of California to cause cancer or birth defects, or other reproductive harm.

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 can 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 Propane 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 the 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 or extension cord.

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

• 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 one-square-foot opening of fresh, outside air.

• 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 in basement or 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. Dust is combustible.

• 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 with hose specified by manufacturer 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.

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.

FUNDAMENTALS 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.

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).

2. Wait a few seconds. Heater will burn gas left in supply hose.

3. Unplug heater.

1. Keep heater clean. Clean heater annually or as needed to remove dust and debris. If heater is dirty or dusty, clean heater with a damp cloth. Use household cleaners on difficult spots.

2. Inspect heater before each use. Check connections for leaks. Apply mixture of liquid soap and water to connections. Bubbles forming show a leak. Correct all leaks at once.

3. Inspect hose/regulator assembly before each use. If hose is highly worn or cut, replace with hose specified by manufacturer.

4. Have heater inspected yearly by a qualified service agency.

5. Keep inside of heater free from combustible and foreign objects. Remove motor and other internal parts if needed to clean inside of heater (see Service Procedures, page 8).

6. Clean fan blades each season or as needed (see Fan, page 9).

TO RESTART HEATER

1. Wait five minutes after stopping heater.

2. Repeat steps under To Start Heater, page 5.

STORAGE

CAUTION: Disconnect heater from propane sup-

ply tank(s).

1. Store propane tank(s) in safe manner. See Chapter 5 of Standard for Storag e and Handling of Liqueﬁed Petroleum Gases, ANSI/NFPA 58. Follow all local codes. Always store propane

tanks outdoors.

2. Place plastic cover caps over brass ﬁttings on inlet connector and hose/regulator assembly.

3. Store in dry , clean, and safe place. Do not store hose/regulator assembly inside heater combustion chamber.
