Configuration of air intake and flue gas discharge ducts
Type B23
Boiler intended for connection to an existing flue system external to the boiler room. Combustion air is taken directly from the boiler room itself
while flue gas is conveyed to the outside.
The boiler does not require any cowl while it must be equipped with a fan mounted before the combustion chamber/heat exchanger.
Type B53
Boiler intended for connection, via an independent duct, to the flue gas discharge terminal. Combustion air is taken directly from the boiler
room itself while flue gas is conveyed to the outside.
The boiler does not require any cowl while it must be equipped with a fan mounted before the combustion chamber/heat exchanger.
Type C13
Boiler intended for connection to horizontal air intake / flue gas discharge ducts connected to the outside by means of coaxial or split ducts.
The minimum distance between the air intake duct and the flue gas discharge duct must be at least 250 mm, whereas both terminals must be
contained within a square measuring 500 x 500 mm.
The boiler is to be equipped with a fan mounted before the combustion chamber/heat exchanger.
Type C33
Boiler intended for connection to vertical air intake / flue gas discharge ducts connected to the outside by means of coaxial or split ducts.
The minimum distance between the air intake duct and the flue gas discharge duct must be at least 250 mm, whereas both terminals must be
contained within a square measuring 500 x 500 mm.
The boiler is to be equipped with a fan mounted before the combustion chamber/heat exchanger.
Type C43
Boiler intended for connection to collective chimney pipe system that includes two ducts, one for air intake and one for flue gas exhaustion.
These ducts may be coaxial or split.
The chimney must be compliant with applicable legislation and standards.
The boiler is to be equipped with a fan mounted before the combustion chamber/heat exchanger.
Type C53
Boiler with separate pipes for air intake and flue gas discharge.
These flues may discharge in areas at a different pressure.
The terminals may not face each other from opposed walls.
The boiler is to be equipped with a fan mounted before the combustion chamber/heat exchanger.
Type C83
Boiler intended to be connected to combustion air terminal and to a single flue gas discharge terminal or collective chimney.
The chimney must be compliant with applicable legislation and standards.
The boiler is to be equipped with a fan mounted before the combustion chamber/heat exchanger.
4.6.1.
Ø 100/60 mm or Ø 125/80 mm air intake/flue gas discharge via coaxial ducts
The information given is with reference to air intake/flue gas discharge ducts made from smooth, rigid pipes approved and
supplied by the manufacturer.
Type C13
KC 24
Minimum permissible length of horizontal coaxial pipes is 1 meter, not including the first elbow connected to the boiler.
Maximum permissible length of Ø 100/60 mm horizontal coaxial pipes is 10 meters not including the first elbow connected to the boiler.
Maximum permissible length of Ø 125/80 mm horizontal coaxial pipes is 14.5 meter not including the first elbow connected to the boiler.
For each additional 1 meter of straight pipe maximum permissible length is to be reduced by 1 meter.
For each additional 90° elbow, maximum permissible length is to be reduced by 1 meter.
For each additional 45° elbow, maximum permissible length is to be reduced by 0.5 meter.
The wall terminal reduces maximum permissible length by 1.5 meters.
The air intake duct is to be tilted down by 1% toward its exit, in order to avoid rain water to enter it.
KC 28
Minimum permissible length of horizontal coaxial pipes is 1 meter, not including the first elbow connected to the boiler.
Maximum permissible length of Ø 100/60 mm horizontal coaxial pipes is 9 meter not including the first elbow connected to the boiler.
Maximum permissible length of Ø 125/80 mm horizontal coaxial pipes is 13.5 meter not including the first elbow connected to the boiler.
For each additional 1 meter of straight pipe maximum permissible length is to be reduced by 1 meter.
For each additional 90° elbow, maximum permissible length is to be reduced by 1 meter.
For each additional 45° elbow, maximum permissible length is to be reduced by 0.5 meter.
The wall terminal reduces maximum permissible length by 1.5 meters.
The air intake duct is to be tilted down by 1% toward its exit, in order to avoid rain water to enter it.
