The charge pressure, with the system cold,
must be between 1 and 1.2 bar.
To empty the system, turn the boiler off
and act on the boiler drain (5 fig. 6).
NB: In "12 T" vers. loading is achieved by
the cock mounted externally from the
installer.

INSTALLATION OF
COAXIAL DUCT
ø 60/100 - ø 80/125
(fig. 8)
The axial suction and discharge pipes are
supplied in a special kit (that can be purcha-
sed separ at el y) along wit h assembl y
instructions.
The diagrams of fig. 8 illustrate some
examples of different types of discharge
modalities allowed and the maximum
lengths that can be reached.
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.

INSTALLATION OF SEPARATE
DUCTS ø 80 - ø 60 (figs. 9-9/a)
The kit with dedicated pipes enables to
separate the exhaust fumes pipes from the
air suction pipes (fig. 9):
- for ø 80 pipes, divider code 8093050 is
provided upon request.
- for ø 60 pipes, divider code 8093060 is
provided upon request.
The maximum overall length, resulting
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 10 mm H
(version 12 T) - 15 mm H
30-35)
(ATTENTION: the total length of each pipe
should not exceed 50 m, even if the total
loss is below the maximum applicable
loss.)

load losses of single accessories and the

Connection to existing flues
The ø 80 or ø 60 exhaust pipe can also be
O
connected to existing flues.
When the boiler runs at low temperature,
it is possible to use standard flues provided
that:
- The flue is not be used by other boilers.
- The interior of the flue is protected to
prevent a direct contact with condensa-
tion from the boiler. The products of
combustion must be conveyed through a
