stove. The duct must be independent and
exclusive to a single equipment; must be
completely clear and clean before installing the
stove.
The masonry chimney or other equivalent
material should preferably be circular, about 20
cm in diameter, or alternatively, it should be
20x20 cm. If the existing duct is oversized, it
must be fully intubated. When there is a too
large section, the draft is reduced, causes rapid
cooling of the fumes, and consequently:
condensation and tar formation. If the duct is
too narrow, it will prevent sufficient evacuation
of the smoke and can lead to its return to the air
inlets of the stove (and possible smoke exit into
the room).
The chimney must be smoke-tight (pay
attention
to
the
impermeable to the weather to prevent water
from entering the chimney, and resistant to
mechanical shocks.
2.5. CHIMNEY ON THE ROOF
The shape of the roof outlet must favor the
escape of smoke, even in the event of wind.
The
chimney
must
corresponding to at least twice the diameter of
the duct. In cases of backflow problems, where
all the conditions necessary for the chimney to
work properly have been observed, an anti-
wind device must be installed. You must make
sure that the chimney prevents the entry of rain.
If the chimney passes near the top of the roof,
it must exceed it by about 60 cm, in any other
area of the roof, the chimney must be 100 cm
above the roof. Special care must be taken to
avoid obstacles (walls, trees, etc.) within a
radius of 8 to 10 m, to prevent any smoke
joining
of
materials),

an
outlet
backflow. If the chimney is placed together with
others, they must have a height difference of
about 50 cm between them, being arranged in
the form of a ladder.

USER INSTRUCTIONS
Local, national, and European regulations and
standards regarding the use of this appliance
must be observed.
3.1. FUELS - FIREWOOD
Your Flamebox equipment is not an
incinerator and as such, for normal
operation, you should only use dry wood with a
humidity level of less than 20%. To obtain this
level of humidity/drying, the wood must be cut
and split, and after a period of exposure to the
weather, stored in an airy shelter, for a
minimum period of 6 to 12 months for soft wood
and 12 to 24 months. for hardwoods. It is
important to mention that in Portugal we use the
term "dry firewood" to identify non-green
firewood and firewood with low humidity. They
are distinct characteristics, green firewood
comes from trees that have been cut recently
and therefore is unsuitable for burning; in turn,
low-moisture firewood is firewood from trees
that have been cut for several months (or
years) and that, after splitting, have been
subjected to a natural drying period (as
described above) and kept from the weather. It
is this firewood that you should use in your
equipment, although on the market you will
hardly find firewood with a moisture content of
less than 30%. Therefore, we recommend that
you purchase the firewood a few months in
advance and allow it to dry in an airy place
without being in direct contact with the ground.
