Fuels such as poplar, pine, lime and chestnut have a low calorific value,
being soft woods, soft in the sense of being pulpy, and they do not burn
long. For all listed types, the humidity contained in them is a
fundamental factor.
A high percentage of moisture produces condensation in the
smoke duct causing an alteration in the draught and
generating smoke and a significant deposit of soot in the
firebox, on the glass of the door and in the flue pipe with a
possible risk of a chimney fire later on. It also causes a
considerable overall drop in efficiency.
The use of damp or treated wood emits a higher quantity of
smoke than normal that can dirty glass faster. Also the low
performance of the chimney flue can jeopardise glass
cleanliness since smoke remains in the combustion chamber
longer than normal.
Do not use treated fuels (such as painted or varnished
wood) or unsuitable materials (such as plastics and
derivatives), which could release toxic or polluting
substances.
Do not burn rubbish.
The gases produced by combustion based on the use
of unsuitable fuels cause damage to the stove and the
chimney, they cause pollution and can significantly
compromise your health.
5.3. STOVE USE
5.3.1. LOADING THE FUEL
To load fuel, simply open the door by rotating/lifting the handle and
pulling the door open.
During use, the metal parts and the glass reach high temperatures, so it
is necessary to use the special thermal glove supplied.
During combustion, the combustion chamber door must remain
closed.
Loading quantities of fuel over those indicated in the
technical sheets for each single product is prohibited.
Excessive quantities of fuel in the combustion
chamber could damage and deform the furnace and
stove structure.
MCZ is not liable for any damages caused by
overloaded fuel of the use of fuel that does not meet
specifications.
5.3.2. CONTROL OF COMBUSTION
According to the stove model, combustion regulation and therefore
combustion air intake is slightly different but always adjustable using a
simple lever or knob. Simply moving or rotating this lever increases or
decreases the quantity of air entering the combustion chamber.
Entering air is divided in:
Wood drying
