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 ENplus standard sets 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

Your pellet stove is only approved for the burning of pellets of tested quality.
Please ask your pellet stove dealer for tested fuel and a list of monitored fuel
manufacturers.
Note
Only burn pellets that have been inspected according to ENplus - A1. 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.
Note
Burning straw, maize, woodchips etc. is not permitted! Observe waste
incineration legislation! Non-observance of these regulations makes void all
warranty and guarantee claims and may impair the safety of the unit!
Pellet container refilling during operation
Note
CAUTION when filling! Avoid direct contact between the plastic bag and the
hot stove. Immediately remove all pellets that have fallen on the hot stove or
next to the container!
We recommend always having a suitable amount of pellets in the container
to prevent the fire from extinguishing due to a lack of fuel. Check the level
frequently. However the container lid should be kept closed, except during
filling.
If you refill the container during operation (open the container lid), the fan will
speed up and the pellet auger will stop; operation will only be continued once
the container lid is closed again (see operating instruction TOUCH DISPLAY)

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.
