Chimney Cap; The Pellets - Extraflame LP30 Manuel Utilisateur

CHIMNEY CAP

The chimney cap must comply with the following requisites:
have an internal section equivalent to that of the chimney;
have useful outlet section not lower than double the chimney internal section;
be built in order to avoid rain, snow, foreign bodies penetrating the chimney and so that, in the event of winds in any
direction and inclination, the discharge of the fuel products is assured.
be positioned in a way to guarantee an adequate dispersion and dilution of the combustion products and, however, outside
the refl ux area in which the formation of counterpressures occurs. Such area has diff erent dimensions and confi guration
depending on the covering inclination angle. It is therefore necessary to adopt the minimum heights indicated in the fi gure
layouts below.
The chimney cap must not have mechanical intake means.
