5.2.3 MEASUREMENTS TO PIERCE BUILDING ENVELOPES
The ducting for the smoke must pierce the building envelope one or more times depending on where the unit is to be
installed.
The size of the holes that will need to be made depends on the diameter of the ducting and of the material to be
penetrated. Once a pipe has been passed through, the space must be filled with an insulating material (rock wool,
ceramic fibre, etc.)

5.3 SMOKE DUCTING OR CHIMNEY
Smoke ducting or a chimney should be used to vent the gases produced by the heater during combustion to the exterior.
The responsibility for the work done to make the smoke ducting lies with the installer, for which reason FERLUX recommends
that the installation be carried out by qualified personnel (who are in possession of an installer’s licence) to whom enquiries
can be made regarding the performance of tests with respect to the smoke ducting, air intake, etc. Furthermore, all the
safety regulations laid out by the specific legislation in force in the country where the unit is being installed must be followed.
5.3.1 GENERAL BACKGROUND
The following points must be taken into account during the installation of the smoke ducting:
• The smoke evacuation system must be unique to each heater (smoke evacuation systems must never be
shared with other units).
• The path of the evacuated smoke must be as short as possible and seek always to be as vertical as possible.
• The internal section of the smoke evacuation ducting system must be uniform and, preferably, circular. In the
event that the section is squared or rectangular, the edges must be rounded with a minimum radius of 20 mm,
bends must be regular and free of irregularities, ensuring that deviations from the path do not exceed 45° with
respect to the axis.
• It is absolutely prohibited to install valves or seals that may obstruct the passage of the smoke.
• Horizontal stretches of the chimney must be avoided, since this causes it to gather dirt and requires the ducting
to be cleaned more often. If such a stretch is inevitable, it must be slightly inclined and a ‘T’ installed at each bend
so that it can be cleaned without requiring disassembly of the entire section. The installation must be carried
out in such a way that regular cleaning is guaranteed without the need to disassemble the entire smoke ducting
assembly.
• The safety regulations and minimum distances must be respected when installing the smoke ducting.
