By means of a splitting kit a two-pipe system may also be installed. In case exhaust and intake flues not supplied by BAXI S.p.A. have been installed, these must be certified for the type of use and must have a maximum pressure drop in according to the values reported in the table (par 12.1). - Page 15 Horizontal flue terminal Ø 110/160 mm installation options LAS flue duct Ø 110/160 mm installation options L max = 10 m Vertical flue terminal Ø 110/160 mm installation options This type of installation can be carried out both on a flat or pitched roof by fitting a terminal, an appropriate weathering tile and sleeve, (supplementary fittings supplied on demand).
- Page 16 … separated flue-air ducting This type of ducting allows to disengage exhaust flue gases both outside the building and into single flue ducts. Comburant air may be drawn in at a different site from where the flue terminal is located. The splitting kit consists of an air cap (160/110) and of an air duct adaptor.
- Page 17 Separated horizontal flue terminals installation options IMPORTANT - Make sure there is a minimum downward slope of 1 cm per metre of duct towards the boiler. Make sure the flue and air ducts are firmly fixed to the wall with suitable brackets. (L1 + L2) max = 27 m The maximum length of the suction duct must be 7 metres.
