4.2 Changing from dual duct fume removal to coaxial fume removal
The Evolution boiler has a Ø80 dual duct system for the removal of combustion products and air
intake. If you prefer the removal of combustion products to be made by means of a Ø80/125 coaxial
tube, you may use the Ø80/125 coaxial tube adaptor kit (supplied to order), code
CGAS000213.

The changeover may be made with two different assembly configurations:
1. Rear outlet: simply remove the combustion air intake from the boiler, unscrewing the three
screws holding it in place, mount the adaptor on the fume outlet towards the rear, and use the
flexible air inlet tube to connect it to the adaptor.
2. Side or top outlet: the procedure is the same, but to mount the adaptor kit laterally a 90º Ø80
elbow (code CGAS000147) needs to be fitted before the adaptor at the fume outlet.
The two
configurations are shown in the
