� For extractor versions (13A), connect the other end of the exhaust pipe to the flue. For filter versions (13F), fit deflector F to the support and secure it to the bracket supplied using 4 screws, then connect the exhaust pipe to the connection ring located on the deflector. � Fit the nuts with fixing hooks (14) supplied inside the top and bottom sections of the flues at the rectangular slots. A total of 10 nuts must be fitted. � Join the two top sections of the flue to cover the support (15) so that one of the slots on the sections is situated on the same side of the control panel and the other on the opposite side. Screw the two sections together with 4 screws (2 each side- see the plan diagram for joining the two sections). � Fix the top flue assembly to the support, near the ceiling, with two screws (16 - one each side).
