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.
If the combustion air is to be channelled, remove the clamp that keeps the pipe fastened to the structure of the product, pull the flexible
pipe and connect to the wall by making a hole for the air to be drawn from outside.
CONNECTION OF THE SMOKE EXHAUST DUCT
When making the hole for the passage of the smoke discharge pipe, one must take into account the possible presence of flammable
materials. If the hole must be made through a wooden wall or thermolabile material, the INSTALLER MUST first of all use the appropriate
wall fitting (minimum diameter 13 cm) and suitably insulate the pipe of the product that passes through it using adequate insulating
materials (1.3 - 5 cm thick with minimum thermal conductivity 0.07 W/m°K).
The same minimum distance must be applied if the pipe of the product must pass through vertical or horizontal sections near the
thermolabile wall. It is recommended to use an insulated double-wall pipe in external sections in order to prevent condensation from
forming. The combustion chamber works in negative pressure.
