EXHAUST AND SUPPLY NETWORK
The ducting installation is composed of insulated PVC ducting
The duct layout should be as simple as possible :
- avoid long ducting runs and severe angles or bends
- install the duct with large sweeping bends
- the flexible duct should not be deformed or flattened
The exhaust network consists of Ø125 mm flexible ducting for the kitchen and Ø80 mm for other rooms such as
bathrooms, toilets etc.
The spigot of the exhaust fan is connected to a roof outlet with duct of Ø150 mm.
The supply network consists of derivations Y branch Ø150/ Ø125/ Ø60. In the case of large dwelling, it is possible
to use a derivation Ø150/Ø150/Ø150 in order to realise parallel supply networks
The fresh air intake is done with duct in Ø150 mm.
IMPORTANTADVICE
: cover the overall duct system with a layer of glass wool (70 mm) so as to avoid
condensation.
