COMBUSTION AIR DRAWN DIRECTLY FROM OUTSIDE

On all our stoves there is the possibility to draw the combustion air directly from outside. With this type of installation
the ventilation grid is no longer necessary, thus eliminating the flows of cold air that compromise the efficiency
of the system.
• Use a pipe with minimum Ø80 mm pipe and a maximum length of 2 metres; to connect the pipe see the back
of the stove.
• During installation step is necessary to verify the minimum distances required for the combustible air inlet as
(for example) an open door or window causes a vortex which could remove the combustible air necessary
to the stove (see the underlying scheme).
• On the external wall it is necessary to install a curve at 90° to protect the combustible air inflow from wind
effects: turn the curve inlet downwards, see Fig. 8 page 10.
• Endow the curve with an external shield grid against birds in such a way that it cannot be obstructed by any
object.
Check with your local authorities if exists any restrictive regulation regarding the combustible
air inlet: if present, they must be applied.

CHIMNEY FLUE CONNECTION

Your stove works through a natural draught. It is obligatory to check that all pipes are realized in compliance
with the following regulation on material selection: EN 1856-1, EN 1856-2 e UNI/TS 11278. All must be effected by
specialized personnel or companies as provided by UNI 10683:2012.
• The connection between the appliance and the chimney flue should be short in order to favor the draught
and to avoid condensation in the pipes.
• The fume conduit should be equivalent or longer than the outlet joint ones.
• Some stove models are endowed with a lateral and/or back exhaust. Check that the unused exhaust is
sealed with the plug given with standard equipment.
