Operation
The fuel
Duroflame pellet stoves use pellets as fuel. Pellets consist of wood fibres that
are pressed together under very high pressure. After which, without any
additives, they take on their solid form. It is
not permitted to burn any raw
materials other than wood pellets in Duroflame pellet stoves
, not even to light the
stove. If this is done, the warranty will be voided and safety compromised.
It is important that the composition of the pellets is of good quality. The quality of the
pellets affects the combustion and fouling of the stove.
It is allowed to use, as fuel, only sawdust-based natural wood pellets (also called
pellets)
certified class A1 according to standard ISO 17225 2 (ENplus A1 or DIN
Plus)
. Any biomass fuel other than these wood pellets is prohibited.
Characteristics of good pellets are:
Diameter: 6-7 mm
Length: 30 mm
Hard pressed
Free of additives, adhesives and resin
Calorific value of 20,244 kJ/kg
Moisture content of 7%
Bad pellets cause the following problems:
Poor combustion
Clogging the burn pot
Blockage of flue pipes
A quickly soiled window
Lots of ash and unburnt pellets
Please note that damp pellets can cause poor combustion and therefore the
above problems. Store your pellets dry and at least one metre away from the
stove. We recommend choosing your pellets carefully. Using bad pellets can damage
your pellet stove, voiding the manufacturer's guarantee and liability.
