Important criteria of wood pellets according to the ISO 17225-2 from 2014:
Quality A1 Quality A2
diameter (mm)
6 or 8
length(mm)
3,15 to 40
moisture content (% by mass)
<=10
ash content (% by mass)
<=0,7 <=1,2
mechanical strength (% by mass)
>=97,5
finest content (% by mass)
<=1
overlength (40 – 45 mm)
<=1
heating value (kWh/kg)
4,6 to 5,3
bulk density (kg/m³)
>=600 600 – 700
nitrogen content (% by mass)
<=0,3 <=0,5
sulphur content (% by mass)
<=0,04 <=0,05
chlorine content (% by mass)
<=0,02
ash fusion temperature* (C°)
>=1200 >=1100
* This value is only mandatory for ENplus certified pellets. It refers to the temperature at
which the wood ash deforms and thus can lead to scorification in the combustion chamber.
Poor quality pellets can impair operation of your heating system and have an adverse effect
on the storage and conveying equipment. Only high-grade pellets can assure reliable and
problem-free operation of the pellet-fired boiler and the conveying systems. If necessary,
have the supplier confirm the quality of the pellets.
ENplus certificate
ENplus certified pellets are available for quality classes A1
and A2. Manufacturers and suppliers of high quality wood
pellets and further information can be found under

1.4 Approvals and Compatibility to Pellet Boilers
There are approvals of various boiler manufacturers for the A.B.S. Flexilo
TROUGH.
Through individual solutions of extraction devices and conveying systems in special cases
connections to the silo can be created.
Please comply with your country-specific standards and directives regarding
assembly and operation of the silo! Observe the information contained in these
instructions! It is binding and must be observed.
