Use the drain tap to empty the system (9).
Turn off the boiler before doing this.
2.6 FLUES/CHIMNEYS
The flue or chimney used to release the
products of combustion into the atmosphe-
re must comply with current legislation.
2.6. 1 Passing flue pipes through
an existing chimney
When renovating or passing flue pipes
through an existing chimney, use only flues
which are declared suitable for the purpo-
se by the manufacturer, following the
instructions for installation and use provi-
ded by the manufacturer.
2.7 INSTALLATION COAXIAL DUCT
(vers. "BF TS")
The air inlet-smoke outlet assembly ø
60/100 is supplied in a kit code 8084811
complete with mounting instructions. With
the curve supplied in the kit the maximum
horizontal length of the flue must not
exceed 3.5 metres in model "25 BF TS" - 3
metres in models "30 - 35 BF TS". The dia-
grams in fig. 6 illustrate a number of exam-
ples of different coaxial outlets.
2.7. 1 Coaxial flue diaphragm
The boiler is supplied as standard with a ø
86 diaphragm (version "25 - 35 BF TS")
and ø 87.5 diaphragm (model "30 BF TS").
With outlet type C12-C42, install diaph-
ragm ø 86 or ø 87.5 only if the coaxial
flue is less than 1 metres long. For C32
discharge options, it is necessary to order
the optional diaphragm separately and use
it in accordance with the instructions provi-
ded in figure 7.

IMPORTANT:
– Each additional 90° curve installed reduces the available
length by 0.90 metres.
– Each additional 45° curve installed reduces the available
length by 0.45 metres.
– It is advisable to assemble the condensation collector
(8) on vertical segments exceeding 2.5 metres in length
and to limit maximum length to 4 metres.
With outlet type C12-C42, install diaphragm ø 86 or ø 87.5 only if the coaxial flue is
less than 1 metres long.
With outlet type C32, use the following diaphragms, depending on flue length and without
any additional curves:
