Hello,
I am in the process of placing the gas boiler which will take over from the wood. The evacuation is in chimney, put there is initially 2 meters of conduit in horizontal. In fact, that makes a 60/100 to 80/125 adapter elbow then a 125 pipe, elbow and sheath adapter (or vice versa) in the chimney.
I wonder about the horizontal part, am I good with 80/125 or I stay on 60/100?

thank you for your comeback
