This type of pipe is used to discharge exhaust gases either to the outside
of the building or into the individual flue gas pipes. Combustion 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 fitting 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
metres.
Insertion of a 45° elbow reduces the total length of the pipe by 0.25
metres.
The first 90° elbow is not taken into account in calculating the maximum
length available.

Pipes in cascade (not provided)
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.
