Safety Information
WARNING:Thisproductcontainsand/orgenerateschemicals 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 fromtheheaterasrecommended 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. Checkwithyourlocalfiresafetyau- thority 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 re- semble 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 odormaking 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.
1.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 Liq- uefied Petroleum Gas, ANSI/NFPA 58 and the Propane Installation Code, CAN/CGA
B149.2. This instructs on the safe storage and handling of propane/LP gases.
2.Use only the hose and factory preset regulator provided with the heater.
3.Use only propane gas set up for vapor withdrawal.
4.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.
5.Do not use heater in occupied dwellings, sleeping quarters, campers, tents, or any type of unvented or enclosed area.
6.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.
7.Do not use heater as a cooking device. Do not place objects on top of heater.
8.Keep appliance area clear and free from combustible materials, gasoline, paint thinner, and other fammable vapors and liquids. Dust is combustible. Do not use heater in areas with high dust content.
9.Minimum heater clearances from combustibles: Sides - 3 feet (1 m), Top - 6 feet (1.8 m).
10.Keep heater at least 6 feet (1.8 m) from propane tank(s).
11.Keep propane tank(s) below 100º F (38° C).
12.Before each use, check heater for leaks. Never use an open fame 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.
13.Check heater for damage before each use. Do not use a damaged heater.

14.Check hose before each use of heater. If highly worn or cut, replace with hose specified by the manufacturer before using heater.
15.Do not alter heater. Keep heater in its original state.
16.Do not use heater if altered.
17.Locate heater on stable and level surface if heater is hot or operating.
18.Never block air inlet (top of base) or air outlet (around top of shell) of heater.
19.Keep heater away from strong drafts, wind, water spray, rain, or dripping water.
20.Never operate heater while sleeping or unattended.
21.Keep children and animals away from heater.
22.Never move, handle, or service a hot or operating heater. Severe burns may result. You must wait 15 minutes after turning heater off.
23.To prevent injury, wear gloves when handling heater.
24.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 fame, or where temperatures exceed 120° F
(49° C).
25.Turn off propane supply to heater when not in use.
26.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.
27.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 fame goes out.
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.

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 tempera- tures. Your local propane gas dealer will help you select the proper supply system.

Installation
WARNING:Testallgaspiping and connections for leaks after installation or servicing. 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.
1.Wrench tighten the fuel connector nut into the propane tank valve (see Figure 2). Turn fuel connector nut counterclockwise to tighten. Threads are left-handed.
2.Connect hose to inlet connector (see Figure
3). Tighten firmly using a wrench.
3.Open propane supply valve on propane tank(s) slowly. Note: if not opened slowly, excess-fow check valve on propane tank may stop gas fow.
If this happens, you may hear a click inside the regulator assembly, this is the check valve clos- ing. To reset the excess-fow check valve, close propane supply valve and open it again slowly.
4.Check all connections for leaks. Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak that must be corrected.
5.Close propane supply valve.
