5.3.- Combustion products exhaustion and air intake horizontally-arranged coaxial
device ø80-125 (type C13) (Only for TRO Evolution System)
The combustion products exhaustion and air intake can be carried out through concentric
pipes of Ø80 mm. for the combustion products exhaustion and Ø125 mm. for the air intake
by means of the horizontally-arranged outlet Kit 1m Ø80-125 code CGAS000189.
The maximum horizontal length counted from the boiler, including the kit end, is 6 metres
(TRO Evolution 30 System) and 8 metres (TRO Evolution 20 System). Each elbow of 90°, or two
of 45°, reduces the available length by 1 metre,.
It is recommended that the flue gases outlet pipe be fitted slightly upwardly-inclined 2º to 3º
thus preventing water and condensate projections from being ejected outside.
