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 stove is approved as a room air dependent
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 con-
necting a sealed air inlet to the stove’s air intake
connector, the stove can be supplied with exter-
nal 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.
• The stove has been tested with 3 m of 100
mm pipe, with 3 90 degree bends.
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 Ambition has a nominal output of less than
Ambition 5: 4,9 kW and Ambition 8: 6,5 kW and
does not need additional ventilation in older
properties where it will be ventilated by 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.
