5.3 Concentric Flue Kit Connection. The connection for combustion air intake
and smoke exhaust is made horizontally or vertically towards the outside
of the room.
WARNING
The fumes condensates should not flow inside the unit,
risk of corrosion. If it is needed, foresee a condensate collector. In case
of horizontal concentric installation, foresee a slope of 2° minimum and
opposed to the unit to drain the condensate.
5.4 Mounting type C12: Flue pipe diameter: 130 mm
5.4.1
Two single elbows at 90°
5.4.2
Two single extensions of 1 m
5.4.3
Concentric wall terminal
•
Condensate trap
NOTE
It is possible to
extend or divert the

approved accessories.
5.5 Roof type C32: Flue pipe diameter: 130 mm
5.5.1
Two single extensions
5.5.2
1 concentric roof terminal
•
Condensate trap
NOTE
It is possible to extend or divert the concentric kit with
approved accessories. The use of flues involves a perfect
sealing. To check the installation, it is necessary to use a
non-aggresive libricant for the gasket, example: soapy water.
NOTE
The junctions must be sealed and rigid. The
section of flue must be at least equal to the diameter
of the heater outlet. The smoke exhaust cannot be
vertical or at 45° minimum. The total length of the
connection cannot exceed 6 m, knowing that:
elbow 90" or 45° = 1 m of flue. If the outside
part of the flue is higher than 2m,
foresee an insulated pipe.
