Measuring the flue (standard flue)

▶ Measure from the outside of the wall to the centre line of the flue
turret to determine length L.
▶ Subtract 50mm from the length L to give the correct dimension to the
flue elbow connection.
▶ If the length L falls within the telescopic range of 350 to 570mm,
then no cutting will be required.
▶ If the required length is less than 350mm the standard telescopic flue
can be modified, refer to following section.
▶ If the required length is greater than 570mm, then flue extensions
will have to be used. Refer to the 60/100 Horizontal Flue Instruction
manual provided in the telescopic flue kit.
