Flue outlet
Air inlet

The Remeha Quinta boiler (twin connection only) is capable of operating with the air
inlet and flue outlet in different pressure zones (CLV System).
There are some restrictions to the flue/air inlet lengths and max height differences
which have been detailed in

Fig. 09.

Maximum total length of air inlet and flue gas outlet pipework (L) as detailed in table
below (calculation based on using 1 x 90 bend).
