In calculating the lengths of the pipes, the maximum length must also take into con-
sideration the values for the exhaust/air intake end terminals, as well as 90° elbows
for coaxial systems.
The C52 types must comply with the following requirements:
1. The discharge/intake vent pipes must have the same diameter of ø 80 mm.
2. If an elbow is inserted into the discharge/ventilation system, the calculation of the
overall extension must take into consideration the values for each curve, as indi-
cated in the table.
3. The exhaust pipe must extend at least 0.5 m above the ridge of the roof if it is
located on a side other than that for the air intake (this is not obligatory if the
exhaust and air intake pipes are located on the same side of the building).
