General Safety Information

Make certain you read and understand all warnings. Keep these instructions for reference. They are your guide to safe and proper operation of this heater.

Safety information appears throughout these instructions. Pay close attention to them. Below are definitions for the safety information listed throughout this manual.

Under this heading,

installation, operating, and maintenance procedures or practices will be found that, if not carefully followed, WILL result in IMMEDIATE serious personal injury or death.

Under this head-

ing, installation, operating, and maintenance procedures or practices will be found that, if not carefully followed, COULD result in severe personal injury or death.

Under this heading,

installation, operating, and maintenance procedures or practices will be found that, if not carefully followed, MAY result in minor personal injury, product, or property damage.

IMPORTANT: Not every possible circumstance that might involve a hazard can be anticipated. The warnings in this manual and on tags or decals affixed to the unit are therefore not all-inclusive. If a procedure, work method, or operating technique not specifically recommended by Dayton is used, you must make sure it is safe for you and others. You should also ensure that equipment will not be damaged or made unsafe by the operating or maintenance method you choose.

Carbon monoxide

poisoning may lead to death! 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 or the areas may not be sufficiently ventilated. 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.

• 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. This instructs on the safe storage and handling of propane gases.-

• 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 sixsquare-foot opening of fresh, outside air. 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 in a basement or below ground level. Propane gas is heavier than air. If a leak occurs, propane gas will sink to the lowest

possible level and may accumulate to explosive concentrations.

• 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: Outlet: 6 Ft. Sides: 2 Ft. Top: 6 Ft. Rear: 2 Ft.

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.

Combustion Chamber

Propane Supply

Propane gas and propane tank(s) must to provided by the customer.

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. 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).
