Only use good quality wooden pellets with a 6 mm diameter and a maximum
length of 30 mm. There are different kinds of wooden pellets with different prop-
erties and varying quality available on the market. Good quality pellets can be
recognised as follows:
- diameter 6 mm.
- maximum length 30 mm.
- wooden pellets comply with 6mm DIN+ / Ö-norm+ / EN+ or equivalent.
- properly compressed, no residual adhesive, resin or additives.
- smooth, shiny surface
- uniform length and low dust content
- residual water content: <10%
- ash content: <0.5%
- good quality pellets sink when placed in water
Poor quality fuel can generally be recognised as follows:
- different diameter than the required 6 mm and/or various diameters
- varying lengths, higher percentage of shorter pellets
- the surfaces exhibit vertical and/or horizontal cracks
- high dust content
- dull surface
- floats in water
Poor fuel may result in:
- poor combustion
- frequent blocking of the combustion chamber
- increased pellet consumption
- low heat output and low efficiency
- soot on glass
- more ash and unburnt granules
- higher maintenance costs
Even when good, standardised pellets are used, it is not unusual for
G
there to be differences in the combustion speed, ash production and
build-up of debris. If a different type of pellet is used to the ones used
during commissioning, the stove must be set up again by a Stover-
approved service technician.
G
Store and transport the pellets in absolutely dry conditions. Wooden
pellets can expand considerably when they come into contact with
water.
Contact the Stover sales person or approved Stover fitter for more information
about pellets.
