I'm considering having our existing boiler replaced with a Keston Celsius 25 and want to continue to use the existing fluing arrangements so that flue gas discharge is at a high level. I can't find enough information on the Keston website to be sure if what I want if feasible.
Current boiler flue:
4" pipe from the top of the boiler enters nearby chimney where it connects with a flue liner that takes it up through the first floor and through the roof space to a weatherproof terminal. The only bends are 45 deg above the boiler and 45 deg into the flue liner at the base of the chimney.Suggested arrangement:
50mm pipe from the boiler to immediately bend 90 deg into the base of the chimney then another 90 deg bend to connect with the existing flue liner.Any thoughts on the feasibility of this approach? Thanks, John Barnes
