4.5.3 Burnout
– automatic detection
Burnout characteristics are determined by MES thermal distribution mod-
ule WVF.
If only “Solid fuel operation” is set on the WVF, “Burnout” with embers
maintenance is undertaken. With all other settings on the WVF, a normal
burnout is undertaken.
– normal
A normal burnout is always undertaken, i.e. the wood is burnt as best as
possible until no more remains without
embers maintenance.
– Embers maintenance
Burnout with embers maintenance is always undertaken, i.e. basic embers
are maintained to make it easier to light up again.
Factory setting: normal
