TECHNICAL TERMS & DEFINITIONS
Air for Combustion Volume of air necessary to the correct combustion of the gas at standard conditions of temperature and pressure. It is expressed in m3.
 
Vent Cowl Flue/chimney/draining pipes top, whose size and shape are suitable to ease the draught necessary to discharge the products of the combustion even in case of abnormal weather conditions.
 
Gaseous Fuel Any aeriform substance that, combining with air oxygen, produces a certain amount of heat.
 
Excess Air Rate difference between the amount of air introduced into the combustion chamber and the air necessary to the combustion.
 
Dry Running Condition in which the temperature of the inner surface of the flue pipe, smoke exhaust duct, chimney flue, chimney, duct pipe is higher than the temperature at which the condensate changes into vapour
 
Wet Running Condition in which the temperature of the inner surface of the flue pipe, smoke exhaust duct, chimney flue, chimney, duct pipe is lower than the temperature at which the condensate changes into vapour, but higher than their freezing point.
 
Draught Regulating Valve Device being integral part of the appliance, placed on the flue system, whose function is to reduce the influence of the draught variations and to avoid any problem to the correct functioning of the burner and to the combustion process.
 
Head Loss Difference between the static pressures measured in two different points of a system that carries a fluid.
 
Nominal Heat Input (Nominal Heat Input of the Appliance) value of the heat input specified by the appliance producer.
 
Useful Heat Maximum amount of heat released in a time unit
 
Heat of Combustion Amount of heat released after the complete combustion of 1 m3 of a dry gas at constant pressure
 
Products of the Combustion They are the products of the combustion of a gas and the comburent air in excess
 
Thermal Surface Resistance Resistance to the heat transport through the walls of a flue pipe, exhaust duct, chimney flue, chimney, duct pipe (in case of casing the thermal resistance must be globally considered in function of the conductivity of the layers of the materials employed from the inner surface to the outside surface.
 
Hydraulically Equivalent Sections Sections that have the same hydraulic diameter.
 
Section Type Shape of the section of a flue pipe, exhaust duct, chimney flue, chimney, duct pipe.
 
Natural Draught Draught inside a chimney flue, chimney, duct pipe caused by the difference of mass density between the products of the combustion (hot) and the surrounding atmospheric air, without any mechanical suction support fixed inside it or on its top.

Equipment

Ventilation Air change necessary to the outlet of the products of the combustion and to avoid combinations with a high rate or dangerous unburnt gases
 
Vent Flap Opening created on the wall of a room to let comburent air to come in.
 
Forced Draught Appliances Appliances in which the discharge of the products of the combustion is activated with a fan, being integral part of the appliance, placed before or after the combustion chamber.
 
Natural Draught Appliances Appliances in which the discharge of the products of the combustion is made thanks to the depression caused by the different specific weight of the atmospheric air and the fumes, between the inlet of the air and the outlet of the products of the combustion.
 
Similar Appliances Appliances of the same type, that use the same type of fuel, with the same heat input (or a heat input that doesn't differ of more than 30%), having the same conditions of combustion and of discharge of the products of the combustion.
 
Air Ducts Piping that conveys into the rooms the comburent air and the air necessary to the ambient air ventilation.
 
Casing Process of renovation of the flue system. By introducing one or more new ducts, a new system is created from a previous installed chimney, chimney flue or technical room.
 
Outlet Height Height corresponding to the top of a chimney flue, chimney, duct pipe, independently from the chimney stack.
 
Backflow Emission of the products of the combustion from the appliance towards the plant room.
 
Ventilation Inflow of the air necessary to the combustion

Flue System

System Adaptation for the Proper Discharge of the Products of the Combustion All the operations aimed at accomplish or reactivate the functionality
 
Height of the Flue Top Vertical distance from the lowest point of the pitched roof and the outlet of the products of the combustion, excluding the chimney stack.
 
Efficient Height of the Chimney Difference of height between the fumes inlet (horizontal section) and the outlet of the products of the combustion, excluding the chimney stack.
 
Chimney Vertical duct that serves the purpose of collecting and exhausting, at an appropriate height from the ground, the products of the combustion coming from a sole appliance or, when permitted, from more appliances on the same level.
 
Flue Pipe A pipe connecting a fireplace or furnace of an appliance with the chimney, chimney flue or duct pipe.
 
Combined Flue System Chimney flue composed of two separated ducts, the first one serves the purpose to pipe the comburent air towards the appliances placed on different floors, the second one serves the purpose to collect and exhaust their products of the combustion. The ducts can be coaxial, adjacent or separated.
 
Multiple Flue Chimney Pipe shared by more appliances placed on different floors of a building. It is usually composed of prefabricated components that, after proper overlapping and junction, form a series of single flues (secondaries) - everyone of them one floor high - and a waste-gas flue (primary) that drains the products of the combustion coming from the secondaries through a special component that acts as a deflector
 
Collective Chimney System Individual flue pipe that collects and exhausts the products of the combustion coming from different appliances placed on different floors.
 
Hood Bell-shaped structure whose aim is to pipe, through the smoke exhaust ducts or the flue pipes, the products of the combustion or the vapours into a chimney/chimney flue/duct pipe or directly in the atmosphere.
 
Structural Characteristics of the Flue System Physical and executive characteristics of all the components of the system.
 
Waste-Gas Flue Element connecting more appliances placed on the same floor, whose aim is to collect and convey the products of the combustion of two or more appliances - of the same type and using the same fuel - to a chimney flue/duct pipe through a pipe/duct.
 
Chimney Stack (Vent Cowl) Device placed at the outlet section of the fumes of a chimney/chimney flue/duct pipe that allows the products of the combustion dispersion in the atmosphere.
 
Condensate Liquid that forms when the temperature of the fumes at some point of the flue system is lower than the the dew-point.
 
Smoke Exhaust Duct A connecting pipe - directly supplied by the producer of the appliance and that is integral part of it - placed between the outlet of the appliance and a chimney flue, chimney, duct pipe or exhaust. It can be in full view or hidden inside the duct of the carburent air (that is in full view).
 
Balance Pipe In a combined flue system, opening or pipe connecting the air duct and the fumes duct into a combined flue.
 
Duct Pipe Duct suitable for receiving negative or positive pressure from the outside, made of one or more mainly vertically developed components, whose aim is to collect and exhaust the products of the combustion, as well as to endure to their components and condensates. It is suitable to be fixed inside a chimney, chimney flue or inside a technical room in the building.
 
Inner Surface The surface of the flue pipe, exhaust duct, chimney, chimney flue, duct pipe that is in contact with the fumes.
 
Multiple System More systems whose air suction ducts and/or fumes discharge ducts are vertically placed in the same compartment/technical room.
