6.5.2. Smoke flap regulation control
* It controls the passage/exit of smoke when the door is opened, that is, when the
equipment is in operation and you want to refill the equipment with more firewood,
when you open the door the flap will open automatically, Figure 16. This will allow a
greater and easier passage of smoke through the chimney, avoiding the return of
smoke from the equipment into the room.

* Note: if the installation has a poor draft, it is possible to adjust the flap stop in order
to facilitate the passage of smoke through the chimney, Figure 17. This operation must
be carried out by a specialised technician.
