Connection with 80 mm pipe system
The unit can be connected to a system of
separate air/flue pipes for a wall or rooftop
outlet as shown on the fig. 10 - 11. Numerous
accessories are available on request to meet
the various installation requirements.
Please refer to the flue manual catalogue or the
price list for additional components.
To check you do not exceed the maximum
permissible flue length, it is necessary to make
a simple calculation before installation:
1. For each component, tables 4 - 5 provide an
"equivalent loss in metres", depending on
the position of installation of the component
(with air intake or flue extraction, vertical
or horizontal).
The loss is called "equivalent length" since it
is compared to the loss of one metre of flue
(defined as equal to 1). For example, a bend
at 90° of Ø80 in flue run has an equivalent loss
of 2.5 linear metres, i.e. it has a loss equal to
that of 2.5 metres of flue length.
2. After completely designing the layout of
the system, add up the losses in equivalent
metres, depending on the installation posi-
tion, of all the components and accessories
in the system.
3. Check that the total calculated loss is less
than or equal to 55 equivalent metres, i.e.
the maximum permissible for this model
of boiler.
For complete flue options please con-
tact FERROLI or check our comprensive
flue manual.
