(especially plastic) damages the compact fireplace
and the flue, and furthermore it is prohibited by
the law on toxic substance emissions.
Quantity of fuel
Avoid introducing an excessive quantity of fuel
and reaching overheating values that exceed those
indicated for the design. The fireplace may be
damaged.
• Use small pieces of firewood
• Create a bed of embers
• To avoid the accumulation of dirt on the glass,
leave the door a bit open during the first few
minutes. This allows any condensation that
forms at the beginning to evaporate without
accumulating on the glass.
Control of the power of the fireplace is achieved
through air inlets. Since fireplace performance
also depends on flue draft, openings have to be
controlled according to your personal experience.
• Responding to modern demands also implies
assuming a number
Respecting nature is one of the most important
of these requirements. Our products are
always the most up-to-date solutions in terms
of technological development. This is the
fundamental premise for a clean, efficient and
irreproachable operation of our fireplaces.
4 - COMBUSTION
CLEAN COMBUSTION
The fundamental premises for clean combustion
include:
Wood has to be dry and non-treated - indicative
value: 15% relative humidity, wood stored in a dry
and well ventilated place for at least 2-3 years.
A fireplace is not a "waste disposal installation".
Combustion of waste and unsuitable material,
such as plastic, treated wood, etc. leads to poor
combustion and cancellation of the warranty!
Further consequences include damaging and
dirtying the device, the flue and the environment.
Too much wood causes overheating: the material
is excessively stressed and the fireplace produces
negative values of combustion gas.
Too little wood or excessively large logs do not
allow the fireplace to reach the best operational
temperature. In this case combustion gas values
are negative too.
of responsibilities.
Warning: Only compressed wooden logs, dry
firewood and lignite blocks can be burnt in
this fireplace. It is not possible to burn plastic,
carpentry treated wood (e.g.: fossil coal blocks or
textiles). Using the fireplace with a fuel different
from that indicated in the manual will render any
manufacturer warranty void.
Combustion inside the fireplace is possible thanks
to the combination of the inflow and outflow of air.
Air is the element that controls the fuel.
Important: Use the supplied glove to control the
primary and secondary air inlets.
Primary air
Completely opening and then closing the primary
air intake allows the combustion to proceed by in-
ertia and heat for a few hours.
Secondary air
During operation it is advisable to keep the sec-
ondary air intake always open.
In this way combustion quality improves; you avoid
useless environment contamination and the glass
remains clean, furthermore it helps avoiding soot
build-up in the fireplace.
You should not continuously supply firewood to
the fireplace because in this way you interrupt
combustion transformation
performance decreases.
First phase: loss of humidity and combustion of
gas substances.
Second phase: transformation of firewood into
coal, increase of heating value and weight loss.
Third phase: maximum combustion performance.
Fourth phase: slow combustion and progressive
power decrease.
Clean firewood combustion is a process similar to
natural decomposition, which means that the CO2
(carbon dioxide) being freed does not increase
or alter the original concentration of CO2 in the
atmosphere.
