What is a Duct Type Ventilation Heater?

A Duct Type Ventilation Heater (HEATER,VENTILATION,DUCT TYPE) is a heat transferring unit utilizing a separate source of steam or hot water as the heat transfer medium. It consists of finned parallel tubes joined together by a header or headers and is designed for installation in the ducts of a forced air circulating system. It may be provided with a flanged outer casing to facilitate mounting of the unit in planned or existing duct work. Circulation of the heated air is achieved by use of a blower or fan not integral with the heating unit.

What is an Immersion Type Electrical Heating Element?

An Immersion Type Electrical Heating Element (HEATING ELEMENT,ELECTRICAL,IMMERSION TYPE) is an electrical device in the form of a resistor consisting of a resistance wire, an insulating material, and a sheath. It is designed to transform electrical current into heat while immersed in a liquid to be heated or in contact with materials to be melted. It may include an automatic control to regulate the amount of heat generated.

What is a Warm Air Heating System Humidifier?

A Warm Air Heating System Humidifier (HUMIDIFIER,WARM AIR HEATING SYSTEM) is a device which, when installed in conjunction with a warm air heating system, injects or releases vapor for the purpose of increasing the relative humidity in a room or building. Excludes self-contained air humidifying units.

What is a Flue Damper?

A Flue Damper (DAMPER,FLUE) is a cast iron or sheet metal plate designed to be installed in a boiler, heater, stove, or furnace flue pipe to control the draft, and/or in an air duct to control the passage of air. Excludes VALVE, BUTTERFLY.

What is an Air Conditioning-Heating Pipe?

An Air Conditioning-Heating Pipe (PIPE,AIR CONDITIONING-HEATING) is a shaped product of sheet metal; round, rectangular, or square in cross-sectional shape. It is uniform throughout its length. Used to conduct air or gas fumes from one area to another.

What is a Stationary Duct Type Heater?

A Stationary Duct Type Heater (HEATER,DUCT TYPE,STATIONARY) is a device capable of producing heat from gas, liquid fuel, or an electrical heating element designed for permanent installation in sheet metal ducts of a forced air circulating system. It consists of (1) a finned, steel burner tube, a combustion air blower, a control panel, and a constant level fuel supply system or (2) a device having a heating element which when connected to an electrical source, directly imparts heat. It may be provided with a flanged outer casing to facilitate mounting in planned or existing duct work. Circulation of the heated air is achieved by use of a blower or fan not integral with the heating unit.

What is a Nonimmersion Type Electrical Heating Element?

A Nonimmersion Type Electrical Heating Element (HEATING ELEMENT,ELECTRICAL,NONIMMERSION TYPE) is an electrical device in the form of a resistor consisting of a resistance wire, an insulating material, and may be sheathed. Includes infrared elements. It is designed to transform electrical current into heat. It may include an automatic control to regulate the amount of heat generated.

What is an Electric Fluid Heater?

An Electric Fluid Heater (HEATER,FLUID,ELECTRIC) is a unit specifically designed for heating fluid by a direct fired method, utilizing electric heating element.

What is an Air Register?

An Air Register (REGISTER,AIR) is an item with a grille, designed to affect the proper distribution of cold or heated air to an enclosed area. It may have adjustable blades on the back to regulate and control the flow of air.

What is an Air Conditioning-Heating Pipe Assembly?

An Air Conditioning-Heating Pipe Assembly (PIPE ASSEMBLY,AIR CONDITIONING-HEATING) is a combination of lengths of pipe and fittings, such as adapters, collars, couplings, elbows, laterals, reducers, tees, and the like, used to conduct air or gas flow from one area to another.

What is an Exhaust Pipe?

An Exhaust Pipe (PIPE,EXHAUST) is a rigid tubular item designed to direct the exhaust gases away from an engine, heater, or the like. For flexible items, see HOSE, METALLIC.
