Pellet properties
The appliance has been tested with all types of pellets available on the market. The pellets must have the following
properties:
- Diameter 6 mm.
- Maximum length 35 mm.
- Maximum humidity content 8 – 9 %.
- 100% wood. Totally additive-free.
- Maximum ash residue 1.1 %.
To obtain good performance from the appliance, we recommend using good quality pellets. Pellets should be poured
into the tank using a shovel, and not directly from the bag.
Good quality pellets should have the following properties:
- Constant diameter cylinders with a smooth, shiny surface;
- There should not be a lot of sawdust inside the packaging;
- After grabbing a bunch of pellets and placing them into a container filled with water, good-quality pellets will sink and
poor-quality ones will tend to float;
- The quality certification data, in particular conformity to international standards such as EN14961-2, DIN 51731 and
O-NORM M7135, should be indicated on the packaging;
- The packages should be intact since pellets tend to absorb humidity. Humidity not only reduces the calorific value
and increases the amount of flue gases expelled, but also causes swelling of the product which may create problems
with the appliance.
The production of pellets must be compliant with some international standards (such as EN14961-2, DIN 51731 and O-
NORM M7135) which establish minimum values for quality checks on pellets. To facilitate the right choice of the
combustible material you can find below one of the most common certification marks identifying the quality of the pellets:
