Ariston 47-116-08. 47-116-09, 47-116-13, 41-116-01 KW 27 kW Exhaust/Air Maximum Extension

In calculating the lengths of the pipes, the maximum length must also take into consideration 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.The maximum combined flue length is 17 m for Models Genus 23/27 MFFI/RFFI and 15 m for Model Genus 30 MFFI. In this case the minimum length for the air intake pipe is 1 meter; the maximum length of ver tical exhaust pipe must be a maximum of 12 m.

3.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 indicated in the table.

4.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).
