VAIO Operating and installation instructions
7. Heating instructions – wood
When the stove is heated for the first time, the paint on its surface hardens. For this reason, the door and
ash drawer should be opened very carefully to prevent the gaskets from sticking to the paint. The paint
may also give off an unpleasant odour, therefore you must make sure that the room is well ventilated.
On the subject fire safety
Approved fuels
VAIO-wood-burning stoves are EN approved in accordance with standard regulations for burning wood
only. We recommend using dried wood with a maximum residual moisture content of 18%. If wood with
a higher moisture content is used, this can result in the accumulation of soot, harmful emissions and
inefficient fuel economy. We advise purchasing a hygrometer to regularly check that the firewood has the
correct moisture content before burning it.
Recommended types of wood
Types of wood such as birch, beech, oak, elm, ash, conifers, and fruit trees can be used as fuel for this
stove. The difference between the different types of wood is not in the fuel value, but in the weight per unit
volume. Since beech weighs more per cubic metre than the same amount of common spruce, it takes
more common spruce to produce the same amount of heat that would be produced from one cubic metre
of beech.
Banned fuel types
Folgende Brennstoffe dürfen nicht verfeuert werden:
• printed paper • chipboard • plastic • rubber • flammable liquids
• Arubbish such as milk cartons • painted, varnished or waterproof timber.
Burning of these materials is prohibited because during combustion, they develop substances that are
harmful to health and the environment. These substances could also damage your wood-burning stove
and chimney, invalidating the warranty.
Storing the wood
A water content of maximum 18% can be achieved by storing the wood outdoors under cover for at least
one year (or preferably two). Wood stored indoors can become too dry and therefore burn too quickly. Ho-
wever, this does not apply to kindling wood which should be stored indoors for a few days before use.
