Wood
Hardwood, such as oak, beech, birch and fruit tree
wood is the ideal fuel for your stove. This type of
wood burns slowly with calm flames. Softwood
contains more resins, burns faster and sparks
more.
Use seasoned wood that contains no more than
20% moisture. The wood should have been
seasoned for at least 2 years. Wood with a mois-
ture content of 20% provides 4.2 kWh per kg wood.
Wood with a moisture content of 15% provides 4.4
kWh per kg wood. Freshly felled wood has a mois-
ture content of 60% and only provides 1.6 kWh per
kg wood.
Saw the wood to size and split it while it is still
fresh. Fresh wood is easier to split, and split wood
dries more easily. Store the wood under a roof
where the wind has free access.
Do not use damp wood. Damp logs do not produce
heat as all the energy is used in the evaporation of
moisture. This will result in a lot of smoke and soot
deposits on the appliance door and in the flue. The
water vapour will condense in the appliance and
can leak away through chinks in the stove, causing
black stains on the floor. It may also condense in
the chimney and form creosote. Creosote is a
highly flammable compound and may cause a chim-
ney fire.
Lighting
You can check whether the flue has sufficient draught
by lighting a ball of paper above the baffle plate. A cold
flue often has insufficient draught and consequently,
some smoke may escape into the room instead of up
the chimney. You can avoid this problem by lighting
the fire as described below.
1. Stack two layers of medium sized logs crosswise.
2. Stack two to three layers of kindling crosswise on
top of the logs.
3. Place a firelighter between the bottom layer of kind-
ling and light the firelighter according to the instruc-
tions on the packaging.

4. Close the appliance door and open the air inlet of
the appliance completely; see Position A on the fol-
lowing figure.
5. Allow the fire to develop into a good blaze until
there is a glowing bed of charcoal. You can then
add fuel and adjust the appliance, see the chapter
"Stoking with wood".

Maximum amount of wood
To stoke continuously at the rated power, wood must
be added every 45 minutes. If you use a smaller
amount of wood each time, you can add wood more
often. Each stove is designed to work with a specific
maximum amount of wood. If you use a larger quantity
of wood, the heat output increases. This can cause
the hearth to be overloaded and parts can be dam-
aged.
