Different Pressure Zones - REMEHA Quinta 45 Technical Information

Example: Quinta 45, total length 10 m, 2 bends 90°.
80 mm: 10 m + 2 x 2 = 14 m < 16 m: flue OK.
Note: If the design parameters are outside the values shown in the above table or
there is any doubt over the flue system, please contact our technical department for
calculation to be undertaken.

The Remeha Quinta boilers (twin connection only) are 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).
