The ducts used for channelling must be the correct size. The ducts from and toward the outside must be thermally insulated
and not subject to vibrations.
The exhaust and supply piping, with nominal diameter equal to 125 mm, must be fixed to the corresponding device points
with clamps or other suitable fastening systems.
If air exhaust or inlet occurs from the roof, the use of a suitable device is required to prevent the formation of condensate
and the entry of rain water.
Condensate drain
During normal operation, condensate forms at the bottom of the device
inside a double tray which has two drains toward the outside. The
connection points are set at the rear bottom of the device. The
condensate drain can be created by connecting two flexible hoses, with
an internal diameter equal to approximately 16 mm, to the drains. Install
both siphons (not supplied) to prevent the formation of air bubbles.
Important instructions:
Winter operation: highly probable formation of condensate; connection of
drain piping with a siphon is mandatory. (fig 8 pos.A) Summer operation:
probable formation of condensate; connection of drain piping is
recommended, with a siphon. (fig 8 pos.B)

Make sure that the device is level to ensure proper functioning.
Diagonally cut the end of the piping.
Note: Set the siphon in compliance with the dimensions
indicated in fig. 9; otherwise, regular operation of the
appliance cannot be guaranteed.
The condensate drain can also be formed making use of the
sewer system of the dwelling.
