Pellet features

The thermo stove has been tested with all types of pellets present on the market. The pellets used must have the following features:



Diameter 6 mm;



Maximum length 35 mm;



Maximum humidity content 8 – 9 %;



100% wood. Total absence of additives.



1.1 % maximum ash residue

For good thermo stove efficiency, we recommend the use of good quality pellets. Pellets must be poured into the tank using a shovel and not

directly from the bag.

In order to recognise pellet of quality it is necessary that:



It is manufactured with constant diameter cylinders and it has a smooth and glossy surface;



There is not a lot of sawdust inside the packaging;



If the pellet is poured into a container of water it will tend to sink if it is a quality pellet, while if it is not, it will tend to float;



The conditions of the quality certification and in particular the compliance with international Standards such as EN 14961-2 Wood pellet class A1-A2

(maximum moisture level of 10%), should be indicated on the packaging;



Packages are intact since pellets tend to absorb humidity. Humidity not only reduces the calorific value and increases exhaust gas, but it also swells

the product which could create problems in the thermo stove.

International Standards must be respected for the manufacturing of pellets as in France, Austria, Germany and recently some countries from Eastern,

also must comply with the EN 14961-2, DIN 51731 and the O-NORM M7135 Standards in the production phase. These Standards establish the minimum

values in order to check pellet quality. In Italy there is no official Standard, but it is recommended to use pellets that respect the previously-mentioned

Standards.

The use of poor pellets or pellets made of any other material can lead to damage of the thermo stove functions and can also make the

warranty null and void and make the manufacturer exempt from all responsibility.

In order to guarantee combustion without problems the pellets must be kept in a dry place.

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.
