drying and storage
drying wood takes time� proper air drying takes approx� 2 years�
here are some tips:
• Store the wood sawn, split and stacked in an airy, sunny place, which is protected
against rain (the south side of the house is particularly suitable)�
• Store the firewood stacks at a hand’s breadth apart, as this ensures that the air flow-
ing through takes the moisture with it�
• avoid covering the firewood stacks with plastic, as this prevents the moisture from
escaping�
• It is a good idea to bring the firewood into the house 2-3 days before you need it�
room ventilation and stoves
there must not be an extractor fan fitted in the same room as the stove as this can cause
the stove to emit smoke and fumes into the room�
the stove requires a permanent and adequate air supply in order for it to operate safely
and efficiently�
In accordance with current building regulations the installer may have fitted a permanent
air supply vent into the room in which the stove is installed to provide combustion air� this
air vent should not under any circumstances be shut off or sealed�
ONLY USE RECOMMENDED FUELS
