The secondary air intake favours the carbon that was not burnt during the first combustion can suffer a post-combustion. This increases the
efficiency and assures that the glass keeps clean.
• In models Volga and Londres, It is possible to adjust the primary and the secondary air intake with the same control (see drawing D1).
• In models of the Kenia series, Madrid Visión, Madrid Rústico, Canadá Visión, Canadá Rústico and Loire-P, the secondary air intake
control is placed on the top of the door and its movement is from the left to the right. The higher entry air is corresponded with the
higher side of the triangle (see drawing D7).
• In Panamá series models, this regulation is located under the door. It is the regulation located on the left of the ash pan (see drawing
D8). When the regulation is completely extracted (outside) it means a greater air entry.
• In all the others models this entry of air exists but it is not adjustable. It is usually placed on the top of the inside of the door, between
the door and the glass (see drawing D9).
Double combustion
Some models of inserts include a double combustion.
With this system we get a second preheated air
input inside the combustion chamber. This allows
a second combustion of the gases not burnt in the
first combustion that achieves a high performance
efficiency, a great fuel saving and reductions in
pollutant emissions.
• The models of the Kenia series, except the
double face models, have this air intake control
hidden behind the lower cover. Its movement is
from the left to the right. The higher entry air is corresponded with the higher side of the triangle (see drawing D10).
• In Panamá series models, this regulation is located under the door. It is the regulation located on the right of the ash pan (see drawing
D11). When the regulation is completely extracted (outside) it means a
greater air entry.
• In all the other models such as Everest Visión, Everest, Lugo, Merida,
Merida-P Bristol and the Canadá, Madrid, Florida and Londres series, this
entry of preheated air exists but it is not adjustable. The air supply is usually
made by little drillings on the back wall of the combustion chamber (see
drawing D12).
The combustion is not always stable. In fact, it can be affected by the weather
conditions or the outside temperature. This modifies the draw of the insert. For this
reason, our inserts have a baffle plate (or double baffle plate) and a draft-diverter
valve that controls and improves the draw.
