60/100 flue length can be increased up to 19.9 metres by
adjusting the parameter C3 to 5. Refer to servicing instructions
for this operation.
80/125 flue length can be increased up to 99 metres by
adjusting the parameter C3 to 5. 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.
