The rules for an efficient and safe flue pipe

Regulations for the flue and the flue pipe system

In a heating system, the fume exhaust system is responsible for the expulsion of combustion residues, which must always come in an optimal way so that it can guarantee maximum efficiency of the system itself.
These important elements are chimneys and flue pipes which together make up a significant part of the entire flue system.
Like any system, this one is also subject to regulations and adjustments to ensure greater safety and efficacy.

Regulations and adjustments for the smoke system

First of all, the flue pipe and the chimney must be suitable for the type and power of the generator. This generator can be of three types depending on whether or not they are connected to a duct or to a fume exhaust device.
The typologies in question are the following: type A, type B and type C.
These generators are also divided by their thermal capacity and based on the number of appliances that the flue pipe will have to serve.

The choice of fuel

Let’s move on to fuel: the choice of material is important because each type (solid, liquid or gaseous) requires different fume exhaust characteristics.
The development of the ducts

For a correct development of the ducts, it will be necessary to calculate that during the flow of the fumes towards the flue pipe, the temperature of the latter gradually drops, giving rise to flow losses. To avoid this and the formation of deposits, the regulations prescribe that the flues must have a mainly vertical course without bottlenecks.

The chimney

Even the flue pipes has its importance and must be installed in any system where combustion fumes are conducted to the roof by means of flues. This terminal is placed at the outlet of the chimney and its task is to disperse the fumes into the atmosphere.

The maintenance of the chimney

The flue maintenance operations are important not only to maintain the energy efficiency of the energy system but also to maintain the safety of the building where it is installed in order to foresee situations of danger and potential risk.
