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.

REQUISITES 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 130 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 100cm
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 130 cm.
Protect all structures that can catch fire from heat radiation.
The hole must be protected externally with a fixed grid. Periodically check that the grid is not obstructed by leaves or similar, thus blocking the air
passage.
If it is not possible to realise the air vent in the wall behind the thermo stove, make the hole in a perimeter wall where the thermo stove is installed.
If it not possible to realise the external air vent in the same room where the thermo stove is installed, this hole can be made in an adjoining room as long as
this room communicates permanently, by means of a transit hole (20cm minimum diameter).
The UNI 10683 Standard PROHIBITS the withdrawal of combustion air from garages, combustible material warehouses, or from activities where
there is a fire hazard.
Do not connect the external air vent to the thermo stove through piping. If there are other heating or suction appliances in the room, air vents
must guarantee an air volume necessary for the proper functioning of all devices.
Only sealed appliances (e.g. C type gas appliances, according to the UNI 7129 Standard) or appliances that do not cause a lower pressure
compared with the external environment can pre-exist or be installed in the place where the thermo stove must be installed.
Extractor fan can cause functioning problems to the thermo stove when they are installed in the same room or space where the appliance is found.
