Pellet features
The boiler has been tested with all types of pellets present on the market. The pellet 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 boiler 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 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 the DIN 51731 and the O-NORM M7135 are written
in the packaging;

Packages are intact since pellets tend to absorb humidity. Humidity not only
reduces the calorific value and increases exhaust flue gas, but swells the product
which could create problems in the boiler.
International Standards must be respected for the manufacturing of pellets as in France, Austria,
Germany and recently in some Eastern countries, also complying 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 boiler
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.
