To guarantee reliability and operation over time of the ducting system, make sure:
- it is used in average atmospheric and environmental conditions, according to current regulations (absence of combustion products,
dusts or gases that can alter the normal thermophysical or chemical conditions; existence of temperatures coming within the stand-
ard range of daily variation, etc.).
- Installation and maintenance must be performed according to the indications supplied by the manufacturer included with the "green
range" ducting system chosen and in compliance with the regulations in force.
- The maximum length specified by the manufacturer must be respected; in this regard:
- The maximum length of the Ø60 rigid ducted vertical section is 25 metres. This length is obtained by considering the complete Ø 80
inlet terminal, 1m of Ø 80 exhaust pipe and the two Ø 80 90° bends at the outlet of the indoor unit.
- The maximum length of the Ø80 flexible ducted vertical section is 25 metres. This length is obtained by taking into account the com-
plete Ø80 inlet terminal, 1m of Ø80 pipe in the outlet, the two Ø80 90° bends at the outlet of the indoor unit and two changes of direc-
tion of the flexible hose inside the chimney/utility room.
- The maximum length of the Ø80 rigid ducted vertical section is 45 metres. This length is obtained by considering the complete Ø80
inlet terminal, 1m of Ø80 exhaust pipe, the two Ø80 90° bends at the outlet of the indoor unit.
- The maximum length of the Ø 50 flexible ducted vertical section is 8 metres straight. This length is obtained by considering the com-
plete Ø 80 inlet terminal, 1 m of Ø 80 outlet pipe, two Ø 80 90° bends at the outlet of the unit and the reduced Ø 80/50 T-union.
