This type of pipe is used to discharge combusted gases either to the out
side of the building or into the individual flue gas pipes. Combustive air
can be taken in from zones different from the discharge zones. The two-
way accessory includes a discharge fitting Ø 110 mm and an air intake fit
ting Ø 110 mm.
The 90° elbow is used to connect the boiler to the discharge and intake
pipes according to requirements. It can also be used as an extra elbow to
couple to the pipe or to the 45° elbow.
Insertion of a 90° elbow reduces the total length of the pipe by 0.5 me
tres.
Insertion of a 45° elbow reduces the total length of the pipe by 0.25 me
tres.
The first 90° elbow is not taken into account in calculating the maximum
length available.

These types of pipes are used to discharge the combustion products from
several boilers interlinked in cascade via a shared flue gas collector. The
collector must be used solely to connect the boilers to the flue gas pipe.
The diameters available are 150 mm and 200 mm. A range of accessories
is available on request.

For this type of extraction, each boiler must be fitted with a flue
gas valve (non-return valve) Ø 110/110 mm.
The calculation of the length of the flue gas pipe must be made by
a qualified technician during the system design phase, in accord
ance with the requirements of the prevailing standards.
