Extending externally is fine. If the gasses cool and condense even

IIRC, the Keston allows a max of only 4m of flue draining back
into the boiler. Anything longer than this and you have to add
additional condensate drain-off points. It shows you how to make
them in the boiler instructions.
This is a Worcester. The makers are best contacted for situations like
this.
