Briefly. Ideal for the composition of flue systems in buildings where there is no suitable technical shaft, the system BI-CONDEX arises from the need to create adequate conditions to allow correct structural evacuation of the fumes resulting from condensing generators.
BI-CONDEX System is composed by a polypropylene inner wall (EUROPLAST system), resistant up to 120° C (product certification UNI EN 14471), fixed to an external wall, realized in stainless steel AISI 304, by an hot forged centering element. Following the directions by the current legislations concerning “gas flue evacuation systems” and “distances between multiple flue systems in the same technical shaft” (UNI 11071 / UNI EN 10845) there are several possibilities in using this product.

Using. Respecting the essential parameters contained in the above-described legislations (product features / installation requirements / appropriate ventilation of the technical shaft) BI-CONDEX series can be totally blocked in the concrete walls, creating appropriate ventilation from the base to the terminal hat of the system. BI-CONDEX series can also be simultaneously used for the evacuation of flue gas and air adduction of the boiler too, using a special terminal hat and carefully following the manufacturer’s instructions concerning the maximum achievable development for coaxial flue systems.

Installation. Classic junction “male-female”: both wall of the system have the same morphology (female coupling facing the top of evacuation) because it requires the installation in technical shaft or “concealed” into the concrete, directly into the wall. Thanks to the meticulous attention and care in the calibrations male and female is guaranteed a perfect seal in coupling with the possibility of rotation of the product to 360 °, avoiding alignment problems typical of conical systems, screw and combined. Combining the system with generators that produce wet smoke or cooking vapors shall be installed in the female seat the gasket, certified and guaranteed according to the European standard EN 14241-1, without having to use “application on site” of silicone caulk and expensive capillary pasta. For a perfect seal and mechanical traction is recommended to use of the special locking clamp, available in two different versions for practical and aesthetic needs.
