60/100 flue length can be increased up to 17.9 metres by
adjusting the parameter. Refer to servicing instructions for this
operation.
Subtract equivalent length value of bends from the allowable flue
length value.
Flue length determination
Flue duct length (L) is measured from lip of the elbow to end of the
flue terminal.
L
L Flue duct length
a Distance of outer lip of terminal to outer wall, a≤50 mm
Note: Flue ducts are inserted 45 mm into elbows and extensions.

Type C33x (concentric flue system)

The boiler draws combustion air from the outside and expels flue
gas to the outside through a concentric coaxial pipe via the roof.
The terminal outlets from separate combustion and air supply
circuits shall fit inside a square of 50 cm and the distance between
the planes of the two orifices shall be less than 50 cm.

60/100 Vertical flue length can be increased up to 19.2 metres
by adjusting the parameter. Refer to servicing instructions for
this operation.
Subtract equivalent length value of bends from the allowable flue
length value.
80/125 mm flue system
To increase the maximum allowable flue duct length, 80/125 mm
concentric flue ducts can be used instead of 60/100 mm. In this
case, C13x and C33x flue systems should start with a 60/100 to
80/125 adapter coupled to the flue outlet.
