Connect any eventual channelling to the hot air distribution circuit to the equipment upper delivery flange, interposing a
vibration damper joint to prevent vibrations being transmitted to the pipes.
WARNING!
The dimensioning of eventual air inlet and outlet channels has to be previewed by qualified personnel in
compliance with the maximal performances of the heater as indicated in the "TECHNICAL DATA".
Connect any channelling in the air recovery circuit to the side opening. The equipment is made to take the connection on
the left and on the right side. To adapt the air intake side it is enough to invert the mounting of the side closing panel/s

guards and protections, which consist of the following:
Air recovery grid/s;
Side closing panel/s;
Burner guard.
