1.26 DUCTING OF FLUES OR TECHNICAL SLOTS
Ducting is an operation through which, via the introduction of one or more relevant pipes, one achieves a system for the evacuation of the
combustion products of a gas appliance, made up from the coupling of an existing or new ducting pipe with a chimney, flue or technical
slot (also in new buildings) (Fig. 34).
Ducting requires ducts declared to be suitable for the purpose by the manufacturer, following the installation and user instructions,
provided by the manufacturer and the requirements of the regulations in force.
Immergas ducting systems
The Ø 60 rigid, Ø 50 and Ø 80 flexible and Ø 80 rigid "Green Range" ducting systems must only be used for domestic use and
with Immergas condensing appliances.
In any case, ducting operations must respect the provisions contained in the standard and in current technical regulations; in particular,
the declaration of conformity must be compiled at the end of work and on commissioning of the ducted system.
The instructions in the project or technical report must likewise be followed, in cases provided for by the standard and current technical
regulations.
