Wood features

Wood is one of the most precious materials offered by nature.
For heating purposes, it must be verified that the features of the wood satisfy some important requisites that must not be ignored, the most important of
which is without a doubt the correct seasoning or drying, in other words the wood must have the correct amount of humidity, around 10-15%, therefore also
the period of the year in which it is felled becomes important. This should coincide with winter. The correct seasoning (at least 2 years) allows to have a fuel
with excellent yield and not very polluting.
It must be kept in covered, well-aired places, already cut appropriately into pieces suitable for the hearth of the thermo stove.
The wood is divided into softwood and hardwood on the basis of the weight in kg of a cubed metre of material. A softwood that weighs about 300-350
kg/m3 is fir, pine, poplar, European alder, chestnut, willow, while hardwood that weighs about 350-400 kg/m3 is beech, ash, carpine, acacia and oak.
Softwood ignites easily, is consumed quickly and develops a long flame and is used in ovens that require a long flame pass. Hardwood is more compact,
the combustion is slower with short flame, lasts longer and is more suitable for domestic central heating.
The wood to be burned for heating purposes has different features according to the plant variety from which it is obtained. Not all woods are the same and
the features regarding the drying time and the calorific value vary from plant to plant. The calorific value depends on the level of humidity and its density.
Woods of excellent quality are beech, carpine ash and acacia
Avoid resinous woods.
The calorific value of the different types of woods depends a lot on their humidity and consequently the
power of the thermo stove is directly affected by the type of wood used, on average a well-seasoned wood has a calorific value of 3200 kcal/kg.

REQUIREMENTS OF THE PLACE OF INSTALLATION

Positioning

The initial phase for better installation of the thermo stove is
that of identifying its best location. Evaluate the following elements to do this:

Possibility of creating an external air vent;

Possibility of creating a straight flue and possibly coaxial at the thermo stove outlet;

Possibility of creating piping necessary to discharge boiling;

Proximity to the main liquid collector and /or the boiler if one already exists);

Proximity or ease of connection to the water system;

Ease of access for cleaning the thermo stove, the flue gas exhaust pipes and the flue.
The thermo stove must be installed on a floor with suitable load capacity. If the existing building does not fulfil this requirement appropriate measures (e.g.
load distribution plate) must be taken.
Once the best location for the appliance is determined, it is possible to position the thermo stove, following the indications below.

Spaces around and above the thermo stove

The figure below indicates the minimum measurements to respect when positioning the thermo stove according to the walls.
Any shelves or suspending ceilings assembled above the thermo stove must be at least 110 cm away from the upper part of the same.

External air vent

While it is running the thermo stove withdraws air from the environment in which it is installed; It is essential that the air is restored through an external
air vent.
If the wall behind the stove is an outside wall, make a 20 cm diameter hole (minimum section 100 cm
Furniture and mobile objects must be positioned at least 15 cm from the thermo stove sides walls; these objects must be moved when servicing the thermo
stove.
It is forbidden to hang shelves or build suspended ceilings above the thermo stove at a distance measuring less than 110 cm.
Protect all structures that can catch fire from heat radiation.
