The Modena HE range
sets a new standard
for the domestic boiler
market. It is the smallest,
lightest and quietest
boiler in its class and
comes with a choice of a
5 or 2 year full parts and
labour manufacturer’s
warranty*.
NOx Class 5+ and
SEDBUK A ratings
demonstrate the
Modena’s outstanding
energy efficiency
standards to provide
what every customer
wants – an exceptionally
reliable boiler that
combines high
performance with
lower fuel bills.
At just 600mm high
the Modena can be
sited in the most
awkward of spaces; a
liftweight of between
28kg and 31.5kg allows
for one-man installation
and an operating noise
level of less than
40dB means it can
hardly be heard.

Note For non standard flue lengths over 1m a fall of 3mm (or preferably greater) per

Essential to the boiler’s operation is the
availability of fresh, clean air and the ability
to dispose of combustion products. This is
achieved through the installation of a flue
which provides ducts to the outside of the
premises.
To optimise safety and performance, Ferroli
flues must always be used with Ferroli
boilers. Ferroli has a comprehensive range
of accessories to suit complex installations
and to enable the extension of flue lengths.
The diagram above shows typical flueing
options.

Notes
In addition, the terminal must not be
nearer than 300mm to an opening in the
building fabric formed for the purpose of
accommodating a built-in element such as
a window frame.
Condensing terminal positions: if the flue is to
be terminated at low level then the potential
effect of the plume must be considered.
The plume should not be directed:
– across a frequently used access route
– towards a window
– across a neighbouring property
For more information on terminal positions
please contact our technical department.
The distance from a fanned draught appliance
terminal installed parallel to a boundary may
not be less than 300mm in accordance with
the diagram below.
