Operation the damper (optional)
Depending on the situation, an external damper can be connected to the
Heat Pure (see section 3.6). Attention! It is not necessary to install a
damper in all situations! After the installer has installed the damper, you
can operate it using the knob on the side of the surround.
When using an original Kal-fire damper, the letters “Auf or +” on the
knob show the open position. “Zu or -” is the closed position. Set the
required position by turning the knob. The position of the damper
depends on the draught in the flue and the way the appliance is being
used:
When lighting the
fire
Damper fully open.
When burning with
closed door
The damper can be closed to 20-50% which will
calm the flames. If you want to top up wood,
open the damper completely, before opening
the door. When the wood is burning to your
satisfaction, you can partly close the damper
again.
When burning with
open door
Fully and permanently open the damper.
