terminal must not be less than 700 mm
(fig. 16).

ging them back together again so as to
obtain a concentric discharge by using the
doubler fitting (7 fig. 17).
In these cases, when assembling, recover
the silicone gasket used on the terminal
adapter (5 fig. 16), 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 7.00 mm
H O ("25" vers.) and 11.00 mm H

vers.). When calculating the lengths of pipe,
take into account the parameters given in
the Table 2.
