10 FUEL
10.1 FUEL
• Use top-quality pellets because they have influence in the calorific value and in ash remains.
• Pellets features are: dimension Ø6-7mm (D06 Class), maximum lenght 40 mm, calorific value 5kWh/kg, humidity ≤ 10%, ash
remains ≤ 0,7%, they must be correctly pressed and not much mealy, without sizing agents, resins and other additives (class
A1 pellets according to ISO 17225-2 (type ENplus-A1) are recommended).
• Not adequate pellets cause a bad combustion, a frequent burning pot obstruction and exhaust conduits obstruction. Further it
decreases the calorific value, soils the glass and increases consumptions and ash and unburnt granules quantity.
Humid pellets cause a bad combustion and running, so please assure you that they are stored in dry places and
far at least one meter from the stove and/or any other source of heat.
• It is advisable to try different type of pellets available on the market and to choose that which gives the best performance.
• The use of bad quality pellets can damage the stove so that the warranty and manufacturer liability fall.
• Pellets of variable quality and size are available on the market: the smaller the pellet, the greater the fuel supply, resulting in
poor combustion
Depending on the type of pellets it could be necessary a parameters adjustment, please contact an Authorized
Assistance Service.
