1.4 Fuel
The boiler is suited for the burning of wood in the form of unprocessed firewood. The water content of the fuel
must be between 15 – 25 %. Approximate value: wood stored correctly for around 2 years. The effects of any
deviations from this guideline should be taken into account.
– ½ m split logs:
max. 55 cm long, approx. 8 to max. 15 cm edge length
; if lengths are very different, e.g.
1/3 m adapted filling should be undertaken!;
always split round logs
with a
Ø of more
than 8 cm!
– Wood briquettes:
additional firing with coarse wood briquettes, according to ÖNORM M7135 (max. length
40 cm, Ø 4 – 12 cm) or DIN 51731
– Residual wood:
provided that the wood isn’t pressure impregnated or coated, e.g. timber, residual buil-
ding wood, etc. If using large boards, adapted filling should be undertaken!
Attention!
Do not fill with dusty fuels – risk of explosion!
Information!
Do not use plastic parts, PVC panels, saw dust or impregnated, glued wood residue and the like –
these cause boiler corrosion and are prohibited by legislation on air purity.
