OUTDOOR INSTALLATION

SHOT
The gases that are formed during combustion, when heated, undergo an increase in volume and,
therefore, assume a lower density with respect to the surrounding cooler air.
This difference in temperature between the inside and outside of the chimney determines a
depression, called thermal depression, which is greater the higher the flue is and the higher the
temperature.
The draft of the smoke duct must be able to overcome all the resistances of the smoke circuit in
such a way that the smoke produced in the stove, during combustion, is sucked in and dispersed in
the atmosphere through the evacuation duct and the discharge duct. fumes.
There are several meteorological factors that influence the operation of the flue, such as rain, fog,
snow, altitude, but the most important is, without a doubt, the wind, which has the capacity to cause
not only thermal depression , but also dynamic depression.
The action of the wind varies depending on whether it is ascending, horizontal or descending wind:
1. An ascending wind always has the effect of increasing the depression and, therefore, the threw.
2. A horizontal wind increases the depression in case of correct installation of the finishing of the
chimney.
3. A downwind always has the effect of lowering the depression and sometimes the invest.
Excess draft causes overheating of the combustion and, therefore, loss of effectiveness of the stove.
Part of the combustion gases, together with small fuel particles, are sucked into the flue before being
burned. This reduces the efficiency of the stove, increases the consumption of pellets and causes
the emission of polluting fumes.
Simultaneously, the high temperature of the fuel, due to excess oxygen, wears out the combustion
chamber prematurely.
On the other hand, insufficient draft reduces combustion, cools the stove, produces smoke casts in
the environment that reduce the efficiency of the stove, and causes dangerous deposits in the flue.
