ᐅ What should you do if the wrong chimney has been installed?

For our new build, the architect planned for a chimney because we wanted a wood-burning stove in the hallway. It was clear from the start that it would be a room-sealed stove and that the chimney needed an air supply. The bricklayer took care of that. The stove installer connected the room-sealed stove. During the first test run today, it was found that the stove isn’t burning properly because it’s not getting enough oxygen. It only burned well when a) the flap was open or b) the duct on the opposite wall was open. The stove installer tried shining a light up the chimney from the bottom through the duct and noticed that the flue pipe almost completely fills the chimney, leaving barely any room for air supply. He suspects the wrong type of chimney was installed. Bingo! So, we immediately called the main contractor, who did the brickwork (around 7 PM today). He wants to check his paperwork tomorrow to see what kind of chimney the building materials supplier actually charged him for... The stove installer also knew of a case where the bricklayers used so much mortar when building the chimney that there was no room left for air supply from above. That required a very complicated fix, poking around on the roof to clear it again. Anyway, it’s a big mess! I’m afraid we might now have to take the stove’s air supply from the living areas, which is obviously problematic in a newly built, fully insulated house.
Does anyone have any experience with this?

In the worst case, you might not be allowed to use the fireplace.

Extracting the air from the living space won’t work either because a well-sealed house doesn’t allow enough air to flow in. Is the stove located on an exterior wall or is there a basement beneath it?Neither. It’s located on an interior wall in the hallway on the ground floor. Behind one side is the kitchen—there’s a custom-built kitchen cabinet in front of it. On the other side is the living room. When we opened the vent in the living room last night, the stove burned really well. Originally, we planned to place a CD shelf in front of the not-so-attractive vents, which we would move once a year when the chimney sweep comes. That shelf is gone now. My husband thinks it can’t be changed anymore. Just keep the vent open and loosely place a plant in front of it. When the stove is burning, open all the doors in the house so that the 120 sqm (1290 sq ft) living area provides enough oxygen; if necessary, open a window from time to time. I read somewhere that 5 sqm (54 sq ft) of living space per kilowatt of stove output is needed for air supply. The stove has 4.9 kW.H

Would it be possible to install a fresh air duct INSIDE the flue pipe, if it’s large enough? Of course, not a makeshift solution, but an approved system.
Otherwise, a surface-mounted solution 😎Where exactly would the surface-mounted solution go? It would have to pass through a core drilling in the ceiling, through the upper apartment, through the attic, and up to the roof?In der Ruine14 Oct 2021 14:57Heidi1965 schrieb:

If the stove does not get enough air, the flue cannot draft properly.
So many things can go wrong. Several people have already died because they underestimated the dangers.
Keep in mind, we are talking about fire inside the house.
