Air necessary for combustion
All types of combustion need air (oxygen). Hence, every stove extracts air from the room in which it is
installed and then the air has to be returned. Bad combustion may be caused by poor air circulation
inside the house and this often occurs in modern homes, which have hermetically sealed doors and
windows. The situation can also be problematical when, on the other hand, there are drafts inside the
room (generated by fans in the kitchen or bathroom for example).
To avoid this type of problem we recommend installing a permanent ventilation grid in a window or near
the stove. Air intake directly from the outside is compulsory.
WARNING!
Use only certified pipes of steel preferably. Pipes in synthetic material must never be used.
Comburent air duct
We recommend to vent the flow of air for combustion purposes directly from the outside through a pipe
with diameter 40 mm, located behind the stove (see page 29) that allows a better combustion with no
risk against safety.
When the installation takes place it is necessary to verify the minimum distances of the comburent air
duct taken directly from the outside as (for example) a window or an open door can take off the
comburent air necessary to the stove (see hereunder table). The duct outlet must be covered with a grid
strainer against birds. If extractor fans are used in the same room or place where the appliance is
installed this may create problems.
