Caution
Ensure that the flue gas discharge pipes are securely attached to
the wall with suitable retaining flanges to prevent any damage and
guarantee the tightness of every gasket in the circuit.

This type of pipe is used to discharge exhaust gases and draw in
combustion air, whether outside the building or in the flue gas pipes. The
90° coaxial elbow is used to connect the boiler to the discharge/intake
pipes in every direction due to the 360° rotation option. It can also be used
as an extra elbow in combination with the coaxial pipe or the 45° elbow. If
discharging to the outside, the discharge/intake pipe must stick out of the
wall by at least 18 mm to allow fitting of the aluminium rosette and its
sealing unit and thus prevent any infiltration of water.
Insertion of a 90° elbow reduces the total length of the pipe by 1 metres.
Insertion of a 45° elbow reduces the total length of the pipe by 0.5
metres.
The first 90° elbow is not taken into account in calculating the maximum
length available.
