COATING AND INSTALLATION OF THE INSERT
When the insert is installed in a facing or an old chimney it is essential the space among the top and the sides of the equipment and the
fireproof material of the hood (which block the base of the chimney) will be constantly ventilated. For this reason, it is necessary to keep an
fresh air entry on the bottom of the facing and an exit on the top (hot air exit) by the hood. The function will be improved due to there is a
natural convection circuit. Every one of these openings must be free and not blocked with a surface of 3 dm2 at least (for example, grille 30
x 10 cm.).
