I have a query about the fluing options on the Worceter Greenstart
30HE.

I wish to vent into an existing brick lined chimney. I will require a
800mm offset and then a riser of about 1500mm to enter the chimney.

Will I require a flue liner, and could you recommend a cowl to go on
the top of the chimney?

Or is the best option to extend the flue from the boiler to top and
out of the chimney, my worry is that the moisture in the exhaust could
cause problems unless vented outside.

Can't wait for that chocolate box picture this winter with the "smoke
effect house"

Thanks
