must be used with caution to avoid harmful overheating of the
stove
Fuels such as poplar-pine-linden-chestnut have a low calorific value as
the wood is soft, i.e. tender, and does not last long. The humidity
content is fundamental for all types of wood.
A high percentage humidity causes condensation to form in
the smoke duct, causing an alteration to the draught and
generating smoke and considerable soot deposits in the
combustion chamber, on the door glazing and on the flue
pipe, with the subsequent possible fire hazard in the same; in
addition, it leads to a much lower global efficiency.
The use of humid or treated wood releases a larger than
normal quantity of smoke, which could soil the glass more
quickly. The poor performance of the flue pipe can also
compromise the cleanliness of the glass, considering that the
smoke remains in the combustion chamber longer than usual.
Do not use treated fuels (painted or lacquered wood)
or non-compliant fuels (plastic or derivatives) which
could release toxic substances or pollutants.
Do not burn waste.
The gases produced by combustion resulting from the
use of unsuitable fuel could damage the stove, the
flue pipe, pollute and compromise your health.
5.3. USING THE STOVE
5.3.1. FUEL LOADING
To load the fuel, simply open the door by lifting the handle and pulling
the door towards you.
During use, the metal parts and the glazing reach very high
temperatures, so it is necessary to use a heat protective glove (not
included).
During combustion, the door to the combustion chamber must
remain closed.
It is forbidden to load larger quantities of fuel than
those specified in the technical datasheets of each
individual product.
Excessive quantities of fuel introduced into the
combustion chamber could damage and warp the
combustion chamber and the structure of the stove.
MCZ will not be held liable for any damage caused by
fuel overloads or by the use of fuels which do not
comply with the specifications.
5.3.2. COMBUSTION CONTROL
The combustion and therefore the combustion air inlet is controlled via
a single control lever.
The inlet air is either:
