Because of the flexibility of the telescopic flue terminal it is not
always necessary to cut an extension pack.
1. Measure the total flue length from the centre of the boiler
outlet to the outside wall.
2. Subtract 70mm from this dimension.
3. Subtract 950mm for each ‘D’ pack to be used.
4. If the remainder Y is 300mm -
525mm this can be taken up 70
by the adjustment in the
telescopic flue.
5. If the remainder Y is 525mm -
950mm it will be necessary to
cut a ‘D’ pack to 400mm.

6. If the remainder Y is less than 300mm, shorten the
previous ‘D’ pack to 400mm and adjust the telescopic
terminal.
7. Measure and mark the length on the flue, to ensure a
square cut mark the flue all the way around and cut to
length.
