the following extraction/suction systems. Before installation, check and carefully observe the above prescriptions. Also,
comply with the provisions concerning the positioning of wall and/or roof terminals and the minimum distances from win-
dows, walls, vents, etc.
Installation type C10
In case of flues under pressure in a collective flue, before installation and at subsequent maintenance operations, close

Installation of the boiler according to type C10 must be carried out by specialist personnel doing the calcula-
tions required by current regulations in compliance with the maximum positive pressure of the flue and the
boiler.
