To locate the centre of the hole for the passage of the pipes in the wall, refer to Fig. 14:
Please consider that the horizontal concentric piping must have a slope towards the boiler of at least 3 mm/
m, to allow the condensation which forms in the flues to flow back to the boiler, and avoid external dripping.
The concentric pipes should be sealed with the relative pipe coupling seal at the points of coupling to the
wall. The external piping must protrude from the wall between 10 and 60 mm (Fig.15).
