Fitting the fl ue system
For a correct installation of the fl ue pipe, re-
fer to the sheet provided together with the
pre-selected kit.
The horizontal routes of the fl ue pipes must
incline about 1.5 degrees (25 mm per me-
ter); therefore the terminal must be higher
than the intake at the boiler.
The single coaxial pipe with the terminal
must be fi tted horizontal as the drainpipe is
already angled with the correct incline.

The horizontal routes of the fl ue pipes must
incline about 1.5 degrees (25 mm per me-
ter).
The terminal must be higher
than the infeed boiler side.
INSTALLATION
The single coaxial pipe with terminal must
be horizontal because the drain pipe is al-
ready angled.
The following kits to be connected to the
boiler are available:
Wall fl ue exhaust kit ( Fig. 6.8 A)
Type C
Fig. 6.8
Coaxial pipe Ø 60/100 mm with a nominal
length of 915 mm.
This kit allows the fl ues to be exhausted in
the rear wall or at the side of the boiler.
The minimum length of the pipe must be no
less than 0.5 m, whilst the maximum with
the aid of extensions must not exceed 10
m.
Vertical fl ue exhaust kit with 90° bend
( Fig. 6.8 B)
Coaxial pipe Ø 60/100 mm.
This kit allows the boiler exhaust axis to be
lifted by 635 mm.
The length must be no less than 0.5 m,
whilst the maximum with the aid of exten-
sions must not exceed 10 m in horizontal
and however, the terminal must always ex-
haust horizontally.
