2-INSTALLATION INSTRUCTIONS
CONNECTION OF THE SMOKE EXHAUST DUCT
When drilling the hole for the smoke exhaust pipe, the possible presence of flammable materials must be considered. If the hole must be
made through a wooden wall or thermolabile material, the INSTALLER MUST first use the relative wall fitting (minimum diam. 13 cm)
and adequately insulate the pipe of the product that passes through it, using suitable insulating material (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.
