AIR CIRCULATION PIPES
It is necessary to create air recirculation inside the structure that covers the insert for correct functioning.
This prevents the appliance from over-heating.
To guarantee this, just realise one or more openings in the lower part and in the upper part of the
covering.
The following measurements must be respected:
Lower part (cold air inlet)  D total minimum surface 600 cm.
The openings in the lower part must be realised below the rest bottom.
Upper part (hot air outlet)  D total minimum surface 600 cm.
The openings in the upper part must be realised above the upper clearance of the insert.
This ventilation system is totally independent from the air intake for combustion!!
