A flexible tube (80 mm) introduced through the chimney of the building.
Depending on the configuration of your home, if the suction cup is not suitable, the evacuation of the combustion gases will be via
a flexible tube with a diameter of 80 mm, a tube inserted into the chimney of the building (diagram attached).
Price of the tubing: 10 meters of PP tubing, including accessories, extra €800 including 6% VAT
Important to know: If you replace an old atmospheric boiler connected to a chimney with a condensing boiler, you must surely tub
the chimney. In this case, the supplement of €800 applies.
