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:
Indication of the standard,
base reference for the quality
classes ENplus
Indication of the quality class
of the certified pellet
(preferable A1)
The use of poor quality pellets or any other material can damage the appliance operation, voiding the warranty and exempting the manufacturer
from all liability.
In order to guarantee trouble-free combustion, the pellets must be stored in a dry place.
REQUIREMENTS OF THE PLACE OF INSTALLATION
Positioning
The initial phase for best installation of the appliance is to determine its optimum location; the following elements need to be considered:
-
The possibility of creating an external air vent;
-
The possibility of creating a straight flue, preferably coaxial to the outlet of the appliance;
-
Ease of access for cleaning the appliance, the flue gas exhaust pipes and the flue.
The unit must be installed on a floor with a suitable load capacity. If the existing building does not fulfil this requirement appropriate measures (e.g. load
distribution plate) must be taken.
The minimum safety distance from flammable materials must be at least 200 mm from the sides and 800 mm from the front of the appliance.
Relocating the appliance should not be done by forcing on the handle, glass or ceramics.
The installation must guarantee easy access for cleaning the appliance, the flue gas exhaust pipes and the flue, and any subsequent maintenance
operation by the Authorised technical assistance centre.
Once you have found the best location for the appliance, position it following the instructions given below.
The appliance must not be installed in small rooms, bedrooms, bathrooms or in areas with an explosive atmosphere.
