Connection to a steel chimney
When fitting a connection from a top outlet stove
directly to a steel chimney, we recommend fit-
ting the chimney tube inside the flue gas spigot
so that any soot and condensation drops into
the stove itself rather than collecting on the ex-
terior surface of the stove.
For connections to chimneys that are run through
ceilings, all national and local regulations regar-
ding distance to flammable material must be fol-
lowed. It is important that the chimney is fitted
with roof support so that the top panel of the
stove is not required to bear the entire weight
of the chimney (excessive weight may damage
the stove).

Combustion air and Ventilation
The insert stove is approved as a room air depen-
dent insert stove in accordance with EN 13240.
All the combustion air in the inset stove comes
from the room in which it is fitted. However, by
connecting a sealed air inlet to the insert stove’s
air intake connector, the stove can be supplied
with external combustion air. In this respect, the
following requirements must be met:
• Only approved materials may be used from
the ventilation unit to the air inlet vent.
• The air inlet vent must be fitted correctly and
insulated to prevent formation of condensate.
The cross section of the vent and grille must
be at least 78 cm².
• If the vent leads out into the open air, please
note that the grille must be fitted with suitable
wind protection. There must be no risk that
the grille can get clogged by leaves, etc.
Ventilation
Adequate ventilation must be provided in ac-
cordance with building regulations (Doc J Oct
2010) especially when installing in newer build
properties when the stove is not going to be in-
stalled to an outside air supply.
The Scan-Line Napoli has a nominal output of
less than 5 kW and does not need additional
ventilation in older properties where it will be
ventilatedby natural leakage.
Houses built after 2008 where the air leakage
rate is less than than 5 m

then a ven-
tilator equivalent to 550 mm

per kW output will
be required (4.5 kW x 550 mm = 2475 mm

) un-
less the stove is connected to an outside fresh
air supply.
