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.

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.

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! 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 Petr oleum Gas, ANSI/NFPA 58 and the Propane Installation Code, CAN/CGA B149.2. This instructs on the safe storage and handling of pro-

pane/LP gases.

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

• Use only propane gas set up for vapor withdrawal.

• For indoor and outdoor use. When used indoors, use only in well-vented areas. Provide at least 120 square inches (774.2 cm2) of fresh, outside air before using heater.

• Do not use heater in occupied dwellings, sleeping quarters, campers, tents, or any type of unvented or enclosed area.

• 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.

• Do not use heater as a cooking device. Do not place objects on top of heater.

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

• Minimum heater clearances from combustibles: Sides: 3 feet (1 meter); Top: 6 feet (1.8 meters).

• Keep heater at least six feet from propane tank(s).

• Keep propane tank(s) below 100ºF (38°C).

• Before each use, check heater for leaks. Never use an open flame to check for a leak. Apply a mixture of liquid soap and water to all joints. Bubbles forming show a leak. Correct all leaks at once.

• 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 the manufacturer before using heater .

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

• Do not use heater if altered.

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

• Never block air inlet (top of base) or air outlet (around top of shell) of heater.

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

• Never operate heater while sleeping or unattended.

• Keep children and animals away from heater.

• Before connecting heater to propane tank, make sure the heater regulator knob is in the “OFF” position. Always connect and operate heater in areas free of open flames.

• Never move, handle, or service a hot or operating heater. Severe burns may result. Y ou must wait 20 minutes after turning heater of f.

• To prevent injury, wear gloves when handling heater.

• Always remove heater from propane tank after each use. Always store propane tank outdoors in a well ventilated space out of the reach of children. Never store propane tank in a building, garage, or any other enclosed area. Never store propane tank near high heat, open flame, or where temperatures exceed 49° C (120° F).

• Turn off propane supply to 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.

• Keep all connections and fittings clean. Make sure propane tank valve outlet is clean. Check the rubber “O” ring on the heater inlet fuel connector for damage before each use. Replace if worn or damaged.

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.

THEORY OF OPERATION

The Fuel System: The hose/regulator assembly attaches to the

propane gas supply. This provides fuel to the heater.

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 lb. (9 kg) tank.

You may need two or more tanks or one larger tank in colder weather. Use a 100 lb. (45 kg) 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.

VENTILATION

WARNING: Provide at least an 120-square-inch (774.2 cm2) opening of fresh, outside air while running heater. If proper fresh, outside air ventilation is not provided, carbon monoxide poisoning can occur. Provide proper fresh, outside air ventilation before running heater.

NOTICE: Because of the metal lubricant used in this product, you may notice some smoking upon initial startup and shut down. This condition is normal and should not occur beyond the first several (5-10) minutes of operation. If you have questions, please call 1-866-672-6040.

3. Plugged gas orifices

WARNING: Never attempt to service heater while it is connected to propane supply, operating, or hot. Severe burns can occur.

REMEDY

1. Open propane supply valve slowly

2. Replace burner/valve assembly

3. Assure ignitor electrode gap is .120" (3.04 mm). Check wire lead for damage. Replace piezo ignitor and/or ignitor electrode as necessary

1. Relight, hold automatic control valve button in 45 seconds

2. Check propane tank(s) for proper gas supply

3. Tighten connection or replace thermocouple

4. Replace automatic control valve assembly

INSPECTING BURNER

WARNING: Heater shell, top, and heated air from heater is very hot during operation. Gradually move in closer to heater to observe flame color. Do not touch heater shell or top. Do not get too close to heated air from heater. Severe burns could occur.

To check for correct burner flame, look through the ventilation holes in the top of the heater to see the burner flame. The burner flame should be mostly blue with slight yellow coloring on the ends. If the burner flame is mostly yellow, the primary air openings on the burner tube under the heater base may be blocked (see Figure 5).

1. Stop heater (see To Stop Heater on page 5) and let cool.

2. Turn heater over to locate the primary air openings on the burner tube (see Figure 5). Remove any debris blocking the primary air openings.
