Results from the table were obtained using pellets certified according to the Austrian and German DIN 51731, DIN PLUS and
ÖNORM M 7135 standards. Note that the CEN (European Committee for Standardization) is currently defining future European
legislations which will regulate the technical specification of this fuel and the economic and environmental aspects related to this
production area.
Fuel characteristics
This stove is mainly characterized by the fact that it uses natural fuel (wood pellet) which is produced in environment-friendly manner
from wood industry waste(chips/sawdust). Chips and sawdust from wood processing operations are, after proper cleaning and drying,
compressed under extremely high pressure to form small cylinders of pure wood: pellets. Each small cylinder may vary in size and thickness,
from 1 to 3 cm in lengthandfrom 6 to 8 mm indiameter.
Wood pellet is mainlycharacterized by low humidity values (less than 12%) and high density (= 600 kg/m
3
), as well as its uniqueness and
compactness which provide high calorie value of this fuel (LHV 4100–5000 kcal/kg).
Wood pellet used as fuel must have excellent qualitative characteristics, such as defined in standards DIN 51731, ONORM M 7135 and
EN plus A1.Example of basic data is listed below.
Standard DIN plus proposes a combination of qualitative parameters proposed by the DIN 51731 standardand the Austrian ÖNORM M
7135 standard.
ATTENTION: Pellet should be produced exclusively from untreated wood sawdust without additional materials.
It is absolutely prohibited to use any liquid or solid fuels other than pellet as a stove fuel.
ATTENTION: In order to optimize the appliance functionality it is recommended to usewood pellets certified by accredited body. The
use of pellets, ones not listed by the manufacturer, may result in appliance malfunction and render the warrantyvoid.
Storingandhandling pelletis an important task and should be performed with care.
-
Fuel must be kept in dry and warm environment.
-
Handle pellet with care to avoid excessive grinding and becoming sawdust.
Compliance of these two simple rules will provide better combustion efficiency and help maintain proper functionality of moving
mechanical components.

1 At the most 20% of pellet can be larger than 7.5 times the diameter D.
2 Standard DIN prohibits the use of any additional substances. However, this prohibition does not apply to smaller heating
systems.
3 At the most 5% of pellet can belonger than 40 mm, maximum length 45 mm.
