1.21 CONCENTRIC KIT C
Concentric kit assembly in C
To aid in the removal of possible condensate forming in the exhaust pipe, tilt the pipes towards the appliance with a minimum
slope of 5% (Fig.33)
1. Position the flanged adaptor (14) interposing the concentric gasket (15) on the appliance, fitting it with the screws (13).
2. Insert the non-return valve kit on flue gas Ø80 in the flanged adapter, taking care to remove the spacer Ø 80 th. 5 mm.
Make sure to fill the flue gas non-return valve siphon with water (Fig. 40):
3. Fit the Ø 125 extension in the flanged adapter.
4. Insert the Ø 80/125 bend on the non-return valve.
For maximum extension of the Ø 80/125 flue and for the installation variables, refer to the figure (Fig. 33).Refer to the relative
tables to calculate the resistance factor (Parag. 1.13).
5. Calculate the distances between the bend and the connection to the collective flue and the shaft.
6. Adapt the extension (10), calculating that the inner pipe of the concentric kit must fit as far as it will go into the collective flue. The out-
er pipe must engage up to the door.

permitted with approved original flue, including the specific
non-return valve), makes it possible to intake combustion air di-
rectly from the shaft where the flue gas exhaust is present in the
collective flue.
The connection to the intake shaft is possible with a Ø
125 flue.
The collective flue coupling for the exhaust is possible
with female Ø 80 flue with gasket (Fig. 34).
