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, operat-

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

Under this heading, installation, operat-

ing, 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, oper-

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

IMPORTANT: Every possible circumstance that might involve a hazard cannot be anticipated. The warnings in this manual and on tags or decals affixed to the unit are therefore not all-inclusive. If a proce- dure, work method, or operating tech- nique 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 operating 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.

Natural Gas: Natural gas has a distinc- tive odor. This odor helps you detect a natural gas leak. However, the odor may fade. Natural 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 and the Natural Gas Installa- tion Code, CAN/CGA B149.2. This instructs on the safe storage and handling of propane gases.

•For Model 3VH18A, use only the hose and factory preset regulator pro- vided with the heater.

•For Model 3VH18A, use only propane gas set up for vapor withdrawal.

•For Model 3VH19A, use only natural gas. Do not attempt to use with propane gas.

•For Model 3VH19A, use only factory preset regulator provided on heater.

•Provide adequate ventilation. Before using heater, provide at least a 3- square-foot opening of fresh, outside air.

•This heater produces carbon monox- ide, 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 basement or below ground level. If a leak occurs, gas may accumulate to hazardous amounts.

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

•Minimum heater clearances from combustibles: Sides: 6 feet, Top: 5 feet.

•Keep 3VH18A heater at least six feet from propane tank(s).

•For Model 3VH18A, keep propane tank(s) below 100° F.

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

•Check hose (if used) before each use of heater. If highly worn or cut, replace with hose specified by manufacturer.

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

•Not intended for use on finished floors.

•Never block air inlet (bottom of shell) 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 unat- tended.

•Keep children and animals away from heater.

3VH19A, 3VH18A specifications

Dayton 3VH18A and 3VH19A are advanced ventilation systems designed to meet the needs of various industrial and commercial applications. Both units are part of a series that prioritizes energy efficiency, reliability, and versatile performance, making them suitable for everything from warehouses to manufacturing facilities.

The Dayton 3VH18A is a direct drive fan with a robust motor that operates at a speed of 1,050 RPM, providing an airflow capacity of approximately 1,400 CFM. Its simple yet effective design enables effective air circulation, ensuring that spaces are adequately ventilated.
