Remeha Quinta 85
36
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).

NOTE:
this system may not be used in areas with adverse wind conditions (i.e. in
some coastal regions).
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

7.3.7 Modular
installations
For flue gas-side and air-side connections for multiple boilers in cascade configuration,
refer to Broag for advice.

7.4.1 Condensate and AAV discharge
Discharge the condensate and AAV relief via a tundish, directly into a drain. Only use
synthetic material for the connecting piping, because of the acidity (pH 2 - 5) and allow
a min. of 30 mm per M to ensure a good flow rate. Fill the siphon with clean water
before firing the boiler. It is not advisable to discharge into an outside gutter, because
of the risk of freezing.
