no flames or to be observed any more, bring the air combustion valve in
the glow keeping position.
The air valve should never be put in this position during the burning and
degassing phase, as by sudden oxygen admission (for ex. opening of the
firing door) the in the combustion chamber “standing gases” can react
with the oxygen.
Adding fuel in a warm fireplace
Bring the combustion air valve in the starting up position („Anheizen“=
AUF ) and load the desired amount of fuel on the glow.
When loading the fuel on the glow bed the fuel is warmed up and the
contained humidity is driven out and evaporates. This leads to a temper-
ature reduction in the combustion chamber. The volatile fuel components
driven out at the same time need sufficiently combustion air so that this
emission-technical phase is fast gone through and the temperature in the
post combustion chamber exceeds ca. 450°C (depending on the type of
insert).
If no more fuel is needed, at the end of the combustion, this means when
no flames are to be observed any more, bring the air combustion valve in
the glow keeping position ("Gluthaltung" = ZU).
The air valve should never be put in this position during the burning and
degassing phase, as by sudden oxygen admission (for ex. opening of the
