Never store freshly cut wood in a cellar, as air and
sunshine are required for drying. However, dried
wood can be stored in a well ventilated cellar.
Storage over one summer results in a moisture con-
■
tent of approx. 40 %. Wood must be stored for sev-
eral years to achieve approx. 20 % moisture content.
Ideal log dimensions
Fig. 4
■
Split log length 45 to 50 cm.
■
Shorter logs must be layered without air gaps in the
boiler hopper.
25 cm logs can be inserted in line one after another.
■
Heating up manually
Before heating up: Check that all required conditions
have been met. (see chapter "Heat-up preparations"
from page 10.
Note
Differing log dimensions can only be layered with
gaps. Gaps reduce the boiler output and increase the
risk of ineffective gasification.
