If the telescopic flue terminal is used it is not always necessary
to cut an extension pack.
1.
Measure the total flue length ‘L’ from the centre of the boiler
outlet to the outside wall.
2.
Subtract 65mm from this dimension.
3.
Subtract 950mm for each ‘D’ pack to be used.
4.
If the remainder Y is 300mm - 500mm this can be taken up
by the adjustment in the telescopic flue.
5.
If the remainder Y is 500mm - 950mm it will be necessary
to use a further ‘D’ pack cut to 400mm.
6.
If the remainder Y is less than 300mm, shorten the
previous ‘D’ pack to suit required length 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.
