Coupling type horizontal concentric kit Ø 60/100.
e exhaust pipe (60 mm Ø) is tted inside the aspiration
pipe (100 mm Ø).
Connection to the boiler is done using a 90° bend (2) that can
be positioned in any direction and which, by means of the
necessary extensions, is connected to the specic aspiration
and exhaust terminal (3).
e maximum overall permitted length beyond the rst bend
(2) is 3 straight horizontal metres.
Coupling type horizontal concentric kit Ø 80/125.
e exhaust pipe (80 mm Ø) is tted inside the aspiration
pipe (125 mm Ø).
Connection to the boiler is done using a 90° 60/100 Ø bend
(2) that can be positioned in any direction and which, by
means of the 60/100-80/125 adapter (3) and necessary ex-
tensions, is connected to the specic aspiration and exhaust
terminal (4).
e maximum overall permitted length beyond the rst bend
(2) is 7.3 straight horizontal metres.

Sealed chamber, fan-assisted conguration
(type C).
Exhaust.
Connection to the fumes exhaust pipes is through a ange (1)
or a anged curve to x to the tting (4) at the top of the sealed
chamber, placing a shaped seal in between (6).
e ange diers according to whether the system is used split
or concentric.
In the rst case, the passage for the intake of combustion air
(5) is closed while in the second case it is used.
To ensure correct operation of the boiler it is necessary to put
a diaphragm (7) on the exhaust tting, between it and the
ange used (1).
ere are dierent diameter diaphragms, mounted according
to the type of pipe and its length (see boiler instruction
booklet).
Intake.
Using the split system, connection to the intake pipes is done
in exactly the same way as for the exhaust pipes, connecting
to one of the two 80 mm Ø holes (2) at the top of the sealed
chamber.
e unused hole is closed with one of the plastic caps (3)
supplied with the boiler.
If coaxial pipes are used, the intake of combustion air is done
exploiting the concentric hole, outside the exhaust tting
(5).
Intake and Exhaust Kits.
e kits and their accessories permit use of four concentric
systems and two split systems.
As regards pressure losses relating to each accessory, the various
possible combinations and the use of the diaphragms depen-
ding on the length of the pipes used, follow the instructions
given for the intake and exhaust terminals (see the boiler
instruction booklet).
e coupling of the accessories (bends, extensions and termi-
nals) is the tted type while sealing is guaranteed by silicone
lip seals.
