REMOVAL OF COMBUSTION PRODUCTS
4.1
ø80 dual duct system for combustion product removal and air intake (type C
53
)
For this type of boiler, combustion product removal and air intake take place through separate Ø80
mm dual ducts, using the Ø80 dual duct outlet kit, code CGAS000265. Evolution Solar HDX boilers
are equipped with this type of fume removal by default.
The maximum length of piping that can be installed is 12 metres, which is the maximum sum of the
metres of the air intake duct and the metres of the combustion product removal duct. Each 90º
elbow, or each two 45º elbows, will reduce the available length by 1 m. One horizontal metre is the
equivalent of 2 metres.
It is recommended to fit the exhaustion duct in a slightly upwardly-inclined direction, at around 2º -
3º, thus preventing any water and condensation from dripping out.
