Equivalent length of options
45° elbow 80mm 1.0m
90° elbow 80mm 2.0m
Subtract equivalent length value of bends from the allowable flue
length value.
Note: The air intake length is 3metres. In case of longer air intake
use, flue outlet duct length must be shortened with the same length.
Type C83x (twin pipes flue system)
The boiler draws combustion air from outside via a separate supply
pipe routed through the external wall, and expels flue gas to a
shared flue system.
The multi served chimney is a system that is part of the building and
has a separate CE marking. The connection between the boiler and
the shaft and, the connection between the boiler and the air intake
system must be obtained via Daikin.
In C83x type units, condensate flow into the unit is not allowed.
