5– FLUE CONNECTIONS
Air combustion is taken directly in the building and by-products are released outside trough a vertical chimney
During the commissioning and maintenance, make sure that:
-
Air combustion inlet and by-products outlets are not blocked.
-
For coaxial flue assembly, check that the 2 circuits (air combustion inlet and by-products outlet) are
independent and airtight ; Check pipes assembly and seals..
-
Not to damage the flue pipes seals when assembling the conduits onto the device, check the sealing
after assembly..
-
The assembly of the flue pipes must be carried out so that no water can penetrate into the device
(danger electrical hazard). For this purpose, please use a purge T-piece and a condensate drain, …
-
For greater lengths, it is essential to provide a condensate drain; this also applies to assemblies using
coaxial flue.
B22 - for MH Eco/MC Eco 16/21/28/35/50/60/80 type
Air combustion is taken inside the building and by-products are
released outside.
The
K B22-80 (ø80), K B22-100 (ø100)
and
K B22-130 (ø130) kits
are made of a T piece (4), 2 one m pipes (3), a terminal part (1). The
K B22-80 kit
is delivered with a sliding drip.
The flue shall be higher than the roof level (400mm minimum).
H dimension is equal to 2150 mm.
It is possible to shorten, lengthen or lead astray the flue thanks to
a wide range of flue accessories (0.5 or 1 m pipes, elbows,…)
* Remark: Flashing(2) is not included
5-2 Connection of flue pipe- B22—for MH, MC and MV Eco types
B22 - for MV Eco 35/50/60/80 type
L’air de combustion est aspiré directement dans le local et
l’évacuation des fumées se fait verticalement en toiture.
Air combustion is taken inside the building and by-products are
released outside.
The
K B2280V (ø 80)
and
K B22130V (ø 130) kits
are made of
a 90° elbow (6), one pipe of 0,5 m (5), a T piece (4), two pipes of
1 m (3) and one terminal part (1). The flue shall be higher than the
roof level (400 mm minimum).
H dimension is equal to 2150 mm.
It is possible to shorten, lengthen or lead astray the flue thanks to
a wide range of flue accessories (0.5 or 1 m pipes, elbows,…)
* Remark: Flashing(2) is not included
Check that air renewal is sufficient: a minimum of 100 m3/h air flow per Minigaz is required
Flue pipes sections shall at less be equal to the starting section. Flue pipes shall be vertical or at the maximum with a
45 °angle.
Total length of flue shall not exceed 6 m ( taking into account than pressure drops in a 45° or 90° elbow are
similar to losses in a 1 m pipe).
If the length of the outside flue is more than 2 meters an insulation shall be installed
