INSTALLATION OF SEPARATE
DUCTS ø 80 - ø 60
(fig. 7 - fig. 8)
The kit with dedicated pipes enables to
separate the exhaust fumes pipes from the
air suction pipes (fig. 7):
- The kit with dedicated ø 80 pipes,
code. 8089912, includes a
SUCTION
DIAPHRAGM THAT IS NOT
used for these
models. To be able to use the air tap, cut
its base with a tool (A) and assemble it
(B).
- The kits with dedicated ø 60 pipes, code
8089913, include a suction collar that
replaces the boiler collar (C).
It is now possible to insert an expansion
or bend in polypropylene without gaskets
or sealant.
The maximum overall length, resul-
ting from the sum of all the suction and
discharge pipes, is determined by the
load losses of the single connected acces-
sories and should not exceed 15 mm H
2
O
(ATTENTION: the total length of each pipe
should not exceed 25 m, even if the total
loss is below the maximum applicable
loss.)
See
Table 1-1/a
for information on the
load losses of single accessories and the
example of fig. 8 for information on how to
calculate load losses.
ATTENTION: Only the “25-30” versions
are supplied with steel diaphragm code
6028605 to be positioned on the fumes

IMPORTANT:
- The insertion of each additional 90° bend
with a diameter of 60/100 reduces the
available section by 1.5 meters.
- The insertion of each additional 90° bend
with a diameter of 80/125 reduces the
available section by 2 meters.
- Each additional 45° curve installed redu-
ces the available length by 1.0 metres.
- During assembly it is important to make
sure that the kit with axial pipes. (1) is
positioned horizontally.
NOTE
Before connecting accessories, it is always
advisable to lubricate the internal part of
the gaskets with silicon products. Avoid
using oils and greases.
