14.4 Heating
1) Combustion air damper maximum 50 % opened (regulator to middle position). Otherwise the
amount of fuel laid burns off too quickly and the temperatures on the appliance become too
high.
2) Throttle valve, if present, 50 % opened. Otherwise the amount of fuel laid burns off quickly.
3) Completely open all available warm air grilles.
4) If there are only embers left in the firebox, stoke up.
14.5 Putting on wood
Please note that the fireplace inserts are not slow-burn fires. These are temporary-burning fires, i.e.
longer continual operation is achieved through repeated stoking up.
No loose or easily flammable items of clothing should be worn when laying the fire.
The right time for stoking up has come when the fuel has almost burnt down to the ember phase.
Place only if more embers are present. Further deposits of wood are then generally no longer neces-
sary.
If nevertheless you would like to continue operating the system, the deposit intervals must be exten-
ded and the deposit quantity reduced (by 0.5 – 1 kg).
Putting more wood on:
1) Fully open air control lever.
ð
This prevents any eddies that would allow flue
gases to escape. If there is one, fully open the
throttle valve.
2) Fully open throttle valve.
3) Slowly open door.
4) Put wood on.
5) Close doors.
6) When the wood is burning properly, close the air con-
trol lever back to about ½ position and close throttle
valve again up to 2/3 (turn to the left).
14.6 Heating in the transition period
In the transition period, i.e. during high external temperatures, a sudden temperature rise can disrupt
the chimney draft so that the fuel gases are not completely drawn off. In this case the appliance must
be filled with smaller quantities of fuel and operated with the air damper/-controller on a higher set-
ting so that the available fuel combusts more quickly (with a flame developing) and the chimney draft
stabilized as a result.
TIP
To prevent resistance in the firebed, the ashes should be removed more frequently.
14.7 Heating with the ceramic flue (heat recovery surface)
If your system is fitted with a ceramic flue (or with a metal heat recovery surface), the the following must
be observed during heating operation:
• During heating operation via the heat recovery surface, the firebox door must not be opened (es-
cape of exhaust gas). When putting more wood on, the deflection flap must first be opened. Only
then can the firebox door be opened.
