e1) S 350 (21.8) W20 to W35 C3, C4, C5 Forest wood chips, hard, untreated
e2) S 350 (21.8) W35 to W50 C3, C4, C5 Forest wood chips, soft/hard, untreated
e3) S 350 (21.8) W50 to W60 C3, C4, C5 Forest wood chips, soft, untreated
f1) S 400 (24.9) W35 to W50 C3, C4, C5 Forest wood chips, hard, untreated
f2) S 400 (24.9) W50 to W60 C3, C4, C5 Forest wood chips, soft/hard, untreated
g) S 130 (8.1) less than W15 C3, C4, C5 Shavings & chips from wood remnants, dry, mixed
h) S 200 (12.5) less than W15 C3, C4, C5 Shavings & chips from wood remnants, dry, mixed
i) S 250 (15.6) less than W15 C3, C4, C5 Shavings & chips from wood remnants, dry, mixed
j) S 350 (21.8) less than W15 P3 Briquettes from wood remnants 20mm (3/4 in) to max. 60 mm (2 in)
k1) S 650 (40.6) less than W10 Pellets P1 conforming to standards, untreated up to 10 mm (3/8 in)
k2) S 650 less than W10 Pellets P2 conforming to standards, untreated D 11 (3/8 in) to 20 mm (3/4 in)
6) Maximum water content allowed, W, (percentage by weight of the total mass)
The maximum water content allowed in the fuel when entering the furnace should be taken from the spec sheets for
the furnace series. With a pre-dryer installed between the furnace and the fuel storage site, extra water content can
be in the fuel stored (see specifications in reference to the order). The water content influences the maximum
furnace output possible, the heat emission required to the pre-dryer and thus the maximum heat emission possible
to the consumers.
7) Other information
7.1) Ash and cleaning
Untreated wood without bark has a proportion of ash less than 0.5% of the fuel mass supplied. All the
specifications regarding cleaning involved are based on untreated wood with bark attached with an ash amount
of 0.8%. The cleaning and maintenance involved for other wood fuels should be adapted according to the
amount, the specific weight and the behavior of the ash.
7.2) Changing fuels
A great change in fuel quality, such as bulk density, water content, dust proportion or ash content might make a
manual correction of the firing parameters necessary (see Operating Manual).
8) Non-woody fuels from biomass
Non-woody fuels from biomass, such as needles, foliage, grain, straw, fruit pits, etc, are usually unsuited as fuel for
trouble-free operation and thus are not approved.
