1. A maximum of 6 extension ducts (one suitably

together.

(39") should be supported with the bracket
provided, suitably adjusted - refer to Frame 33.
3. Only use water as a lubricant during assembly.
Do not use mineral based oils.

35 FITTING THE KIT

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 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 Y -
400mm.
6. If the remainder Y is under 300mm,
shorten the previous 'D' pack to 400mm
