15.5 SEPARATED HORIZONTAL FLUE TERMINALS INSTALLATION OPTIONS
IMPORTANT
: Ensure a minimum downward slope of 1 cm toward the outside per each metre of duct length.
In the event of installation of the condensate collection kit, the angle of the drain duct must be directed towards the
boiler.
NB:
For C52 types, terminals for combustion air suction and combustion product extraction must never be fitted on op-
posite walls of the building. The maximum length of the suction duct must be 10 metres.
If the flue duct exceeds 6 m, the condensate collection kit (supplied as an accessory) must be fitted close to the
boiler.
