Firewood
Only burn wood that has been seasoned for at least one full year (two years is better).
If the wood has not been seasoned or dried, energy will be lost in evaporating the wa-
ter held in the wood. Furthermore, condensation or creosote might occur in the stove
and pipe when damp wood is burnt.
Freshly cut wood contains approx. 60-70% water and is completely unsuited for burn-
ing.
Log size should be about 2” (5 cm) less than the width of the firebox

All types of wood heat equally per pound; however, the density of wood is not the
same as is shown in the table below, where the combustible value of wood dried for
two years with a moisture of 15-20% is taken into account. See table to the left.
Drying and storage
Wood to be used for burning in a stove should be dried for two years to ensure optimal
burning.
Here are some storage tips:
• Cut and split the wood before storing.
• Keep the woodpile in a dry sunny place, protected from the rain. Do not cover the
pile with plastic, because that prevents the wood from drying properly.
• Stack the wood with enough space between the rows to ensure good air circulation.
• Bring the logs inside the house two-three days prior to use.
