Separate-pipes roof outlet
To install this kind of arrangement, the following are avai-
lable on request:
– roof outlet terminal ø 80, length 1240 mm (Code
8091201);
– tile with articulated joint (Code 8091300);
– extension ø 80, length 1000 (Code 8077303);
– int.-ext. ring kit ø 80 (Code 8091500);
– 90° pipe elbow MF ø 80 (Code 8077404);
– locking junction for separate flue kits ø 80 (n° 5) (Code
8092700)
– air-intake terminal ø 80 (Code 8089500);
– doubler fitting (Code 8091400);
– separate-pipes kit ø 80 (Code 8089902);
– 45° elbow MF ø 80 (Code 8077406);
– extension ø 80, length 130 with intake (Code
8077304);
– 90° elbow MF ø 80 with intake (Code 8077407);
– condensation outlet ø 80 (Code 8092800)
When assembling the accessories, remember that the
roof outlet terminal (length 1240 mm) cannot be shorte-
ned and that the articulated joint of the roof tile allows roof
pitches between 25° and 45°. The tile is a plane roofing
pipe (1, Fig. 17) and is provided with a shaped and fol-
ded lead panel (dimensions 160 x 440) for adaptation to
the roof. When joining the tile to the terminal, use the col-
lar inserted on the latter (3, Fig. 17), fastening it in posi-
tion with the three self-tapping screws provided. When
positioning the roof tile make sure to leave a distance of
not less than 430 mm from the discharge top of the roof-
outlet terminal. There is the possibility of doubling the air-
intake and smoke-outlet pipes and then bringing them
back together again so as to obtain a concentric dischar-
ge by using the doubler fitting (7, Fig. 17 bis). In these
cases, when assembling, recover the silicone gasket
used on the terminal adapter (5, Fig. 17), which is to be
replaced by the doubler, and insert it into the seat made
in the doubler.
For this type of discharge the sum of
the maximum rectilinear development allowed for the
pipes must not exceed 16 metres. Pipe bends may be
inserted, but remember that each bend penalizes the
rectilinear stretch by 1 m, both on the smoke dischar-
ge and on the air intake portions of piping.
When calculating the lengths of pipe, take into account
the parameters given in section 2.7.2.
Below are illustrated some of the connecting systems that
may be adopted (Fig. 17 bis).
