3.2.6.2. Air intake and flue gas discharge configuration – model KR 55
These values refer to air intake and flue gas discharge systems comprised of original smooth and rigid pipes supplied
by the Manufacturer.
Types B23 and B53 (Ø 80 mm)
With this type of boiler, place one of the caps and seals provided
on one of the two air intakes in the top of the boiler.
The minimum length of the flue gas discharge pipe is 1 metre.
The maximum length of the flue gas discharge pipes is 55 metres.
With pipes up to 30 metres in length, fit a 47mm air intake dia-
phragm in the other air intake in the top of the boiler.
For each additional 90° elbow the maximum length must be redu-
ced by 2.5 metres.
For each additional 45° elbow the maximum length must be redu-
ced by 2 metres.
The roof terminal decreases the maximum length by 1 metre.
The wall terminal decreases the maximum length by 1 metre.
Type C13 (Ø 60/100 mm or 80/125 mm)
With this type of boiler, place both caps and seals on both air inta-
kes in the top of the boiler.
The minimum length for horizontal coaxial pipes is 1 metre, exclu-
ding the first elbow connected to the boiler.
The maximum length for 60/100 horizontal coaxial pipes is 5 me-
tres, excluding the first elbow connected to the boiler.
The maximum length for 80/125 horizontal coaxial pipes is 13
metres, excluding the first elbow connected to the boiler.
For each additional 90° elbow the maximum length must be redu-
ced by 1 metres.
For each additional 45° elbow the maximum length must be redu-
ced by 0.5 metres.
The wall terminal decreases the maximum length by 1 metre.
The air intake part must be angled 1% downwards in the outlet
direction to prevent rainwater from getting in.
Type C33 (Ø 60/100 mm or 80/125 mm)
With this type of boiler, place both caps and seals on both air inta-
kes in the top of the boiler.
The minimum length for vertical coaxial pipes is 1 metre.
The maximum length for 60/100 vertical coaxial pipes is 5 metres.
The maximum length for 80/125 vertical coaxial pipes is 13 metres.
For each additional 90° elbow the maximum length must be redu-
ced by 1 metres.
For each additional 45° elbow the maximum length must be redu-
ced by 0.5 metres.
The roof terminal decreases the maximum length by 1 metre.
Types C43 - C53 - C83 (Ø 80 + 80 mm)
With this type of boiler, place one of the caps and seals provided
on one of the two air intakes in the top of the boiler (the one not
used for air intake).
The minimum length of the air intake pipe is 1 metre.
The minimum length of the flue gas discharge pipe is 1 metre.
The maximum length of air intake and flue gas discharge pipes is
55 metres (adding the intake and discharge length).
With pipes up to 30 metres in length, fit a 47mm air intake dia-
phragm in the air intake in the top of the boiler.
For each additional 90° elbow the maximum length must be redu-
ced by 2.5 metres.
For each additional 45° elbow the maximum length must be redu-
ced by 2 metres.
The roofl terminal decreases the maximum length by 1 metre.
The wall terminal decreases the maximum length by 1 metre.

For each additional 90° elbow the maximum length must be redu-
ced by 3.3 metres.
For each additional 45° elbow the maximum length must be redu-
ced by 1 metres.
The roof terminal decreases the maximum length by 1 metre.
The wall terminal decreases the maximum length by 1 metre.
Types C43 - C53 - C83 (Ø 80 + 100 mm)
The minimum length of the air intake pipe (Ø 80 mm) is 1 metre.
The minimum length of the flue gas discharge pipe (Ø 100 mm) is
1 metre.
The maximum length of air intake and flue gas discharge pipes is
43 metres (adding the intake and discharge length).
For each additional 90° elbow on the air intake pipe the maximum
length must be reduced by 5.5 metres.
For each additional 90° elbow on the flue gas dischage pipe the
