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?

So the stove has been approved and works with the fresh air intake vent open.
Where is the problem now? If @Heidi1965 means the service hatch by "vent," then not everything is fine. This hatch is not meant for fresh air supply but for the chimney sweep and should be kept closed during operation.
An open fireplace door is also not suitable for continuous use.
However, if the stove actually has a fresh air intake vent, contrary to expectations, the situation is different.

hampshire14 Oct 2021 22:24You are right, @In der Ruine, the stove definitely needs its own damper. If not, the proposed solution would be for the builder to provide a different stove.
you should proceed differently:
A: Only agree on things in writing from now on
B: The builder and/or their bulk supplier should offer you a refund because the stove "as installed" cannot be operated properly; it should definitely be possible for you to install a smaller stove that fits the existing pipework
C: The chimney sweep should provide written confirmation whether the stove works properly or not

But if the stove is supposed to be operated with air supply through the chimney, it must have a connection to the chimney—does the stove have this?
If not, it is operated with air supply from the room, and then I think the draft of your chimney simply doesn't match. This would also explain why it works when you open the service flap.
