3. BRIEF INFORMATION ON FUEL - PELLETS
What are pellets?
Wood pellets are a standardised fuel. Every manufacturer must adhere to certain
conditions in order to enable flawless, energy-efficient heating. Pellets are made
from wooden waste, from sawmills and planning workshops, as well as from
residue from forestry operations. These “starting products” are crushed, dried,
and pressed into Pellet “Fuel” without any bonding agent.
ENplus – Pellets
This new pellets are a standard sets new benchmarks in the European pellet
market. The traceability of pellets is ensured thanks to the use of identification
numbers. The pellet manufacturers’ production facilities and manufacturing
processes are reviewed every year. A quality assurance system ensures
the pellets comply with the requirements of the new standard and that the
conditions for trouble-free heating are guaranteed

Note
Please ask your pellet stove dealer for tested fuel and a list of monitored fuel
manufacturers.
Using poor quality or prohibited pellet fuel will have a negative effect on the
function of your pellet stove and can also lead to the warranty becoming null
and void, as well as the product liability connected with this. Observe waste
incineration legislation!
Only burn pellets that have been inspected according to ÖNORM, DIN Plus
or ENplus-A1.
Pellet storage
In order to guarantee problem free burning of the wooden pellets, it is imperative
necessary to store the fuel as dry as possible and free from impurities.
Pellets should not be kept in sacks outdoors or stored in a manner where
they are exposed to the environment. This can lead to blockages in the screw
conveyor
Note
“screw stoppers” are excluded from the warranty.
Note
Your pellet stove is only approved for the burning of wood or pellets of
tested quality. Burning straw, maize, woodchips etc. is not permitted! Non-
observance of these regulations makes void all warranty and guarantee
claims and may impair the safety of the unit!
