Exhaust connections :
Double flow ventilation system 2 x Ø 80 mm (type C53)
Any duct crossing a wall that exceeds the ambient temperature by more than 60°C must be thermally insulated at the site of this
crossing. The insulation can be carried out using an appropriate insulating material with a thickness ≥ 10mm and a thermal conductivity
≤ 0,04 W/m.K (e.g.: glass wool). The terminals for combustion air intake and waste gas exhaust must not be installed on opposite walls
of the building.

Each time an extra 90° is needed (or 2 at 45°), the length (L)
must be reduced by 2m.
Double flow ventilation system 2 x Ø 80 mm for individual
or collective flue (type C83)
The flow of condensates from collective flue systems into the boiler is
not allowed.

Individual or collective flue
The c83 exhaust connection is performed by piercing into an
individual or collective flue (1). The diameter of duct (1) is to be
calculated depending on the total power of the appliances connected.
