TECHNICAL DATA
1.20 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, ue or technical
slot (also in new buildings) (Fig. 32).
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
e Ø 60 rigid, Ø 50 and Ø 80 exible 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.
e instructions in the project or technical report must likewise be followed, in cases provided for by the standard and current technical
regulations.
To guarantee reliability and operation over time of the ducting system, make sure:
- it is used in average atmospheric and environmental conditions, according to current regulations (absence of combustion products,
dusts or gases that can alter the normal thermophysical or chemical conditions; existence of temperatures coming within the standard
range of daily variation, etc.).
- Installation and maintenance must be performed according to the indications supplied by the manufacturer included with the “green
range” ducting system chosen and in compliance with the regulations in force.
- e maximum length specied by the manufacturer must be respected; in this regard:
• e max. possible length of the Ø 80 exible ducting vertical section is equal to 18 m. is length is obtained considering the Ø 80
complete exhaust terminal, 1 m of Ø 80 pipe in exhaust, two 90° Ø 80 bends at appliance outlet for connecting to the ducting system
and two direction changes of the exible hose inside the chimney/technical slot.
You can also install an additional Ø 50 exible ducting system the specications of which are found on the relevant instructions
sheet inside the kit.
