3.13 Connecting the collectors to the exterior ventilation ducts
The collectors can be joined to the ventilation ducts allowing the transport of hot air towards the
ventilation unit.
Ventilation ducts with acoustic insulation applied to their interior is recommended. It is also
possible to paint the ducts black. The absence of insulation or black paint is not recommended
but is not critical to the system’s performance.
