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 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.
