Suitable fuel
The firewood must be air-dry, i.e. it must have dried for
at least one year and have a water content under 20%.
We recommend using half-metre split logs with an
average diameter of 10 cm.
Do not split round logs with a diameter under 8 cm;
instead place them between the split logs in the
middle.
Boards may only be added between the logs and in no
case should they be included in the first layer as they
would block the burn-through opening in the grate.
Small pieces of fuel may only be burned as a minor
addition placed among the split logs, but never in the
bottom layer. The smaller the pieces, the less of them
may be added.
Wood briquettes measuring 6 cm to 10 cm in diameter
in compliance with ISO 17225-3:2014.
Only 1 oversized split log or 1 stump piece can be
placed in the top layer, but no more. Complete
burning may require 2 combustion phases.
Unsuitable fuel
Wet fuel with a moisture content in excess of 20% may
not be burned as it results in condensation which can
lead to corrosion of the boiler's fuel chamber walls.
The following also may not be burned: rubbish, paper
and cardboard (only for start-up), wood dust from
sanding, sawdust, pieces of wood smaller than thumb-
sized, coal and coke, and fuels generally prohibited by
local air quality regulations, such as old railway
sleepers, plastic-coated plywood, impregnated wood,
etc.
