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.

CLEARANCES

via an openable panel

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
