CMtech®: is an exclusive mixture of refractory materials and is designed to withstand very high temperatures and thermal
shocks. Such a high performance is made possible thanks to the thickness and physical structure of the CMtech® material,
which may only become damaged in very exceptional cases (cracks and/or erosion) if subjected to high impact stress. It is
therefore highly recommended to load the wood logs into the combustion chamber with the utmost care, leaning the logs
instead of throwing them against the walls in CMtech®. The same care must be used while handling the CMtech® parts during
the maintenance works. Also note that any fissures and crackles on the CMtech® lining surface do not negatively affect the
efficiency of the material and are not prejudicial to the performance and correct functioning of the appliance.

1.4 Firewood
The following paragraphs provide technical and practical information regarding the fuel used, so that the user will understand the
importance that Caminetti Montegrappa gives to the selection and preparation of the fuel, and the correct use of the appliance, which
will have a significant impact on proper functioning as well as minimizing fuel consumption and pollution.
Renewable, coming from trees and plants, which grow under the action of sun light.
Organic, being produced by living organisms.
Neutral as regards carbon dioxide released into the atmosphere ("neutral CO₂"), since the CO₂ produced after the combustion
is that absorbed during photosynthesis.
Clean since burning wood efficiently and completely produces only natural substances that are abundantly present
everywhere in our environment in non-toxic concentrations for the living organisms.


1.4.1 Characteristics of firewood
Firewood is usually classified into softwood (poor or fair quality) and hardwood (good quality) depending upon its specific weight;
hardwood, which weighs more than softwood, allows to reduce the amount of wood needed.

Softwood weighs about 300-350 kg/cu.m (with 15/20% moisture content):
it is easy to ignite, it burns rapidly and provides a lively fire.
Softwood includes the following species: fir, ailanthus, locust, chestnut, cypress, cornelian cherry, mulberry, larch, alder, pine,
poplar, willow, elder and lime.
Hardwood weighs about 350-400 kg/cu.m (with 15/20% moisture content):
it has a higher density and is less resinous than softwood, it burns slowly and keeps a low flame (suitable for home heating).
Hardwood includes the following species: maple, white birch, hornbeam, bitter oak, cherry, beech, ash, holm-oak, walnut, olive,
elm, pear, plane, oak and false acacia (those highlighted are among the best wood types).
As seen above, firewood for heating has different features according to the tree species it comes from. There are different types of
wood and their properties in terms of heat value vary from species to species. The heating value of wood fuel (kcal/kg) is the
quantity of heat produced after the complete combustion of 1 kg of wood.
The heating value of the different wood types is not only affected by the density, but also by their moisture content; as a
consequence the output and the efficiency of the appliance is strictly dependent upon the type of wood burned (normally the
heating value of a well seasoned wood is 3200 kcal/kg).
Here find some comparative data:
SOFTWOOD = kcal/kg 2800 - 3400.
HARDWOOD = kcal/kg 3400 - 3900.
WOOD BRIQUETTES = kcal/kg 3850 - 4200.
WOOD PELLET = kcal/kg 4200 - 4600.
Firewood is:
Corticated timber at a natural state, in pieces or not (logs, or briquettes free of any binders or additives, kindling, shavings from
processing trees), deadwood like branches and pine cones.
Wood residues created by the furniture manufacturing or the construction industry, provided they are not painted or treated.
Firewood is not:
Any wood scrap coming from house demolition, restoration or renovation, or coming from packing material (pallets), wooden
furniture, Formica, even if mixed with natural wood.
Any other wood material such as painted, varnished and treated wood scraps even if mixed with natural firewood.
Wood is the only source of energy that is:
Softwood produces more creosote with consequential need for more frequent cleaning of your chimney flue.
The only fuel admitted for the appliance use is firewood and its by-products.
The use of any other type of solid fuel (e.g. coal) is FORBIDDEN.
If possible, avoid the use of resinous wood as it can produce obstructions, which damage the inner parts of the
appliance firebox and the chimney flue.

1.4.2 Preparing firewood
The firewood manufacturing processes vary greatly depending upon the final type of fuel to produce: wood pieces, briquettes or
pellets.
Wood pellets or briquettes are produced only in big sawmills that have large quantities of shavings and sawdust at disposal, which
become valuable products for an appealing market.
Individuals who are landowners can easily obtain the amount of wood that will be needed for their home heating.
Those who are not landowners can address dealers experienced in firewood combustion, who can advise about quality and wood
species locally available.
The most important steps in producing firewood are the following:
Cutting of trees or suckers (usually on waning moon or in winter).
Trimming of the smaller branches from the trunk (usually when they are less than 4 cm in diameter).
Cutting of trunks and branches into 1 m long logs.
Cutting of the bigger logs in half along their length (quartering).
Piling of the sawn logs in a dry, ventilated location favouring preliminary wood drying.
Covering the upper part of wood piles with clothes as shelf from the rain.
Cutting of the wood logs into small pieces whose length will vary to suit the user's needs. Final wood stacking in a dry,
ventilated location away from rain and humidity.
Air-drying for at least:
2 years (outdoor).
1 year (indoor, in an adequate place).

1.4.3 Purchasing firewood
The units of measurement commonly used in selling firewood are mainly three:
Cubic metre (cu.m): unit of measurement referring to any type of wood and corresponding to 1cu m of solid wood (the weight
of 1cu m of wood varies greatly depending upon species and humidity).
Stere (metre) (sm): unit of measurement referring to the stacked wood pieces and corresponding to 1 cu.m including the air
space between the pieces of stacked wood. The amount of wood contained in a space of 1 stere depends upon species,
relative moisture content, diametre and shape of the wood pieces, and the way in which they have been stacked (one stere of
wood logs 1 m long corresponds to approximately 0,7 cu.m of wood).
Quintal (q): officially suppressed, this unit of measurement (100 kg; 0,1 t) is still the most widely used in selling firewood.
"Deadwood" does not necessarily mean "dry wood": the dryness of wood is greatly determined by the time it takes
to dry but also by the place where wood is stored for seasoning. Should the wood be stacked for a long amount of
time without providing any protection or be kept in a humid, unsufficiently aerated place, it will rot and decay
easily under the action of mildew with consequential lost of its heating value.
Knowing the type of firewood and its moisture content, if it is sold on a space basis, allows you to get an idea of its heating
value, whereas it is not necessary to know the species of wood if it is sold on a weight basis as with an equal moisture
content the heat value differs slightly.
The heating value of wood varies greatly depending upon its moisture content, thus when you buy wood as a source of
energy it would be better knowing its moisture content.
If we compare as a way of example a piece of beech having a moisture content of 30% with a well seasoned piece of the
same wood type having a moisture content of 15%, the latter will release 25% more heat. When the moisture content is
50% the heat value is reduced by the half.
Purchase of green, damp or wet wood, could mean that you are also buying the water inside. To be sure the firewood you
have purchased has been seasoned for about one year, you should always buy your firewood in the summertime (June-
July) since trees are mostly cut in autumn.
Be careful with any painted or treated wood whose combustion can give off harmful fumes, and whose use is only allowed
in authorized combustion plants.

1.4.4 Combustion
When wood burns there are three stages of combustion:
DRYING: Moisture in wood is removed by evaporation by means of the surrounding fire. Any type of wood contains a
percentage of moisture. Since part of the heat produced by the fire is used for evaporation, it is more convenient and less
polluting to burn well-seasoned wood (max. 20% moisture) rather than green wood freshly cut (with 50% moisture or more).
This stage is over when the wood temperature reaches 100°C (water boiling point).
PYROLYSIS: At a higher temperature wood breaks down chemically and volatile gases and char are formed. When temperature
is between 260°C and 315°C this char and a small amount of these gases break into flames and wood burns. Most of these
gases will then be expelled through the chimney unless the temperature of the appliance is high enough to burn them. As
soon as these gases pass through the chimney they will mix with moisture to form creosote.
GASIFICATION AND COMBUSTION: Gases (smoke) and charcoal (wood residues) burn. Charcoal start burning and releases heat
between 540°C and 705°C, then become ash. Most of the usable heat is produced during this stage. Volatile gases, when mixed
with the proper amount of oxygen, ignite when temperature is between 600°C and 650°C. But gases rarely reach the above
temperature, unless they are conveyed towards flames or towards an area inside the firebox where this temperature has been
reached.

In practice the three stages are interwoven in a complex way during the combustion of every single piece of wood.
The incomplete combustion of wood results in toxic emissions. Note that the worst is the emission level the lower the heat
produced by the combustion process (e.g.: the use of big wood pieces results in slow combustion and low temperatures within the
fireplace, which affects negatively both the appliance and the chimney; the use of green, damp wood, which cannot burn
completely, results in soot and creosote formation collecting rapidly on the chimney walls).
On the contrary, in case of complete combustion (with well-seasoned wood and pieces of appropriate size) we reach a higher
temperature thus reducing the overall amount of the wood needed.
To ensure complete combustion and high efficiency the following conditions must be met:
The wood used must be dry and well-seasoned (with about 15/20% moisture content).
Your wood-burning appliance must be designed in such a way as to ensure that:
High temperatures are reached into the firebox.
Gases emitted in the combustion process are kept at very high temperatures for long time.
There is a sufficient amount of oxygen the gases emitted in the combustion process.
Compared with the past, new wood-burning appliances have been ameliorated with the aim of reducing emissions and increasing
efficiency.
This appliance has a fumes baffle at the top of the hearth, which ensures a higher and steadier temperature inside the combustion
chamber, which maximizes combustion and reduces wood consumption and the release of pollutant emissions.
On the fire bed remain the ashes, which are organic residues that may be used in gardening as soil fertilizer (about 2-3 litres once a
year every 10 sq.m).
