    2-INSTALLATION INSTRUCTIONS COMBUSTION AIR (2) During operation a certain amount of air is drawn from the room in which the product is installed and this air must be supplemented through an external air inlet. The combustion air in this product is autonomously drawn directly from the front grille, however, the user can have the air drawn from outside by removing the clamp on the pipe and connecting it directly to outside.

  • Page 13: Connection To The External Air Intake

    2-INSTALLATION INSTRUCTIONS CONNECTION TO THE EXTERNAL AIR INTAKE It is essential for the room where the product is installed to be adequately ventilated in order to guarantee sufficient air for proper combustion in the appliance. This is possible by means of suitable ventilation openings in the room itself or in an interconnected room through a permanent opening between the rooms.

  • Page 15 2-INSTALLATION INSTRUCTIONS OPERATING PROBLEMS RELATED TO DRAUGHT DEFECTS IN THE CHIMNEY Among all the weather and geographical conditions that affect chimney operation (rain, fog, snow, altitude a.s.l., exposure to sunlight, orientation to the cardinal points, etc.), the wind is certainly the most determinant. In fact, besides the thermal depression caused by the difference in temperature between inside and outside the chimney, there is another type of depression (or overpressure): dynamic pressure caused by the wind.
