Pellet features
The central heating cooker has been tested with all types of pellets available 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 a good performance of the central heating cooker, we recommend using good quality pellets.
Pellets should be poured into the tank using a shovel, and not directly from the bag.
To recognise good quality pellet, make sure:
It is made up of constant diameter cylinders, and has a smooth, glossy surface;
There is not a lot of sawdust inside the packaging;
If the pellet is poured into a container full of water, it will sink if it is good quality, and
it will tend to float if it is not;
The references of quality certifications and in particular 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 as pellet tends to absorb humidity. Humidity not only reduces
the calorific value and increases flue gas, but swells the product, which could create
problems in the central heating cooker.
International standards must be complied with for pellet manufacture as already happens in
France, Austria, Germany, and recently some Eastern countries, which also have to comply with
DIN 51731 and O-NORM M7135 standards in the production phase. These standards establish the
minimum values to check pellet quality. In Italy there are not official rules, but it is recommended
using pellet meeting the previously-mentioned standards.
The use of poor pellet or any other material can damage the central heating cooker features,
voiding the warranty and exempting the manufacturer from all responsibility.
In order to ensure problem-free combustion, the pellets must be kept in a dry place.
