CHIMNEY COWL

The chimney draft also depends on the chimney cowl.
The chimney cowl should assure the smoke discharge even during windy days, having into account that it must exceed the top of the roof
(drawing D32).
The chimney cowl must comply with the following requirements:
• It must have the same interior section of the chimney.
• It must have a usable exit section that is two times the one of the interior of the chimney.
• It must be constructed so that the rain, snow or any other objet do not enter inside.
• It must be easily accessible in order to do servicing and cleaning tasks.
It the chimney cowl is metallic, due to its own design adapted to the diameter of the pipe, the smoke discharge is assured. There are different
models of metallic chimney cowl, fixed, anti-return, and rotary or extractor.

OUTSIDE AIR INTAKE

For the proper operation of the insert, it is essential that there is air enough for the combustion and re/oxygenation of the environment where it
is installed. In the case of houses built under the requirements of "energy efficiency" with a great degree of air tightness, it is possible that the
air intake is not guaranteed *the fitter must assure compliance with the Technical Building Code. This means that the air must be able to move
for the combustion through some openings connected to the exterior, even when doors and windows are closed. Moreover, it must comply
with the following requirements:
