WARNING

NOT FOR HOME OR RECREATIONAL VEHICLE USE.

The heater is designed for use as a construction heater. The primary purpose of

construction heaters is to provide temporary heating of buildings under construc-

tion,alterationorrepair,andtoprovidetemporaryemergencyheat.Properlyused,

the heater provides safe economical heating. Products of combustion are vented

into the area being heated.

Wecannotforeseeevery usewhichmaybe madeofourheaters.Checkwithyour

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

monoxidethanothers.Earlysignsofcarbonmonoxidepoisoningresembletheﬂu,

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.

• For indoor use only. Provide adequate ventilation.

• Do not use heater outdoors or in occupied dwellings.

• Do not use heater in living or sleeping quarters.

• 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.

• 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.

• Use only in well-vented areas. Before using heater, provide at least three

square feet of fresh, outside air opening 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.

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

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

• Never attach duct work to heater.

• Neverblockairinlet(bottomofshell)orairoutlet(aroundtopofshell)ofheater.

• Keep children and animals away from heater.

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

• Minimum heater clearances from combustibles: Sides: 4 feet,

Top: 6 feet-2 inches.

• Install and use heater with care. Follow all local ordinances and codes. In the

absence of local ordinances and codes, refer to ANSI/NFPA 58. This in-

structs on the safe storage and handling of propane gases.

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

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

using heater. Use the replacement hose assembly that is specified by the

manufacturer.

• Use only propane gas set up for vapor withdrawal.

• Keep propane tank(s) below 100°F.

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

• Never move, handle, or service a hot or operating heater. Severe burns may

result. You must wait 30 minutes after turning heater off.

• To prevent injury, wear gloves when handling heater.

• Turn off propane supply to heater when not in use.

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

• Do not use heater if altered.

• 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.

IDENTIFICATION

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 pilot fuel supply.

The Automatic Control System: The automatic control valve shuts off the

heater if the flame goes out.

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.

SUPPLY

You must provide propane gas and propane tank(s).

Use this heater only with a propane vapor withdrawal supply system. See

Chapter 5 of the Standard for Storage and Handling of Liquified Petroleum Gas,

ANSI/NFPA 58. 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 liquid propane gas in tank(s)

2. The temperature of tank(s)

The chart below shows the minimum number of 100-pound tanks needed to run

the heater. Connect tanks together with a manifold. Do not operate this product

with any tank smaller than 100 pounds.

Less gas is vaporized at lower temperatures. Two or more 100-pound tanks or one

larger tank may be needed in colder weather. Your local propane gas dealer will

help you select the proper supply system.
