4.3 Combustion products exhaustion and air intake horizontally-arranged coaxial device
ø80-125 (type C
13
)
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
for model EV 30 FDX; and 5 metres for model EV 40 FDX. Each elbow of 90°, or two of 45°,
reduces the available length by 0.6 metres.
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.
