INSTALLATION
a
If there are other heating or extraction devices inside
the room, the air vents must guarantee a sufficient
amount of air for properly operating all the devices,
in accordance with the regulations in force and the
manufacturer's indications.
Only sealed appliances (e.g. C-type gas appliances,
■
according to the UNI 7129 standard) or appliances
that do not cause a lower pressure compared with
the external environment can pre-exist or be installed
in the place where the wood-burning appliance is in-
stalled.

FUME EXHAUST
l
The fume exhaust is an important function for the
product's efficient operation. It must be made by
qualified personnel and in accordance with the reg-
ulations in force, with regard to both its dimensions
and the materials used to build it.
a
The product works with the combustion chamber in
negative pressure and the fume exhaust under pres-
sure; it is essential that the fume exhaust duct is her-
metically sealed.
For example purposes, we list below the main parts making it up; for
detailed information on the various possible solutions, consult the
successive chapters.

In making the flue gas exhaust, the following indications MUST be
observed:
- the flue must have a minimum cross-section with a diameter equal
to or larger than the appliance's fume exhaust as specified in the
chapter
"Technical
Specifications"
- it is mandatory to have an initial vertical section of at least 500
mm to ensure proper fume exhaustion
- it must go upwards, after the vertical section, for the entire remain-
ing part, with a gradient equal to or above 45%, the inclined section
must not be longer than
1/4
or flue, and nonetheless must not be longer than 2000 mm
- make no more than 2 direction changes, besides the one deriving
from the rear connection of the appliance to the flue, using elbows
with 45° angle or tee fittings
- always use a tee fitting with inspection cap at each horizontal or
vertical variation in the fume exhaust path
- if they are not self-supporting, anchor the pipes with appropriate
collars to the wall, so that their weight does not interfere with the
proper exhaustion of the combustion fumes
- the pipes must guarantee the fume tightness indicated in the
echnical
Specifications" chapter, and must nonetheless withstand
at least 400°C
- the pipes must have a double wall (thermally insulated) or be
suitably insulated with rock wool.
