4.2 Double conduit to coaxial exhaustion transformation (Only for EV 20/30 HFC)
The boiler Evolution is given prepared for the exhaustion of the products of combustion and air
intake by means of the system of double conduit of Ø80. When you want to carry out the
exhaustion of combustion gases by means of coaxial tube of Ø80/125, you will use for it a Kit
adaptor for coaxial tube Ø80/125 (given under order) Code CGAS
Kit adaptor for coaxial tube

80/125
Cod. CGA Cod. CGAS000222
The transformation will be able to realize with two different mounting setups:
1. Back exit: it will be enough with disassembling the combustion air intake of the boiler,
unscrewing the three screw, mount the adaptor in the exit of flue gases of the boiler backwards
and using the flexible tube of entry of air, connect it to the adaptor.
2. Lateral or upwards exit: it will be realized in the same way, but to mount the adaptor kit
laterally it is necessary to mount an elbow of 90º Ø80 (code CGAS000147), before the adaptor
in the exit of flue gases.
In the following pictures they can observe both setups:
