Does anyone have any recommendations on which power flue is the quietest and if any offer the ability to shutoff the vent to prevent draughts (I've heard Matchless fires have some kind of system to close the vent off, I'm not sure if this can be retro-fitted to any other system though)
I can not understand why the previous occupants decided not to use the original class-2 flue - I've seen you can get open fires that can be used with these type of flues.
Thanks in advance for any advice.
