Hello,
this thread might not fit perfectly into the planning section, but there isn’t a more suitable subforum. Besides, it’s about planning how to get the fireplace to work properly.
I have already searched several trade forums but couldn’t find a solution to my problem.
It concerns a probably poorly built open fireplace in a semi-open room:
The room is a freestanding area that can be fully opened on two sides, a kind of garden/leisure/grill/windbreak space. An open fireplace was built along one long wall, but not really by a professional. It’s all abroad, after all.
Therefore, it’s not about any DIN standards, regulations, or legal requirements, nor do we need any heating effect. The main function is grilling and creating a cozy atmosphere.
The fireplace is masonry, with an opening to the room of 90cm (35 inches) wide and 95cm (37 inches) high. The flue above is built with offset bricks inward and leads into a square chimney (also masonry) measuring 35cm by 38cm (14 by 15 inches). This chimney section is 1.4m (4.6 feet) high and has a cover with side openings.
And, of course, it doesn’t work properly: smoke spreads everywhere, through the chimney but just as much into the room.
Here are the pictures:
Front view:
Looking upward at an angle, the concrete beams are supposed to support the chimney:
View into the chimney; the chimney cap is 70cm (28 inches), and the chimney itself is 1.4m (4.6 feet):
Now I’m wondering if the cross-section of the chimney for an open fireplace can be smaller than the air intake, meaning the open area?
Does the chimney opening at the top have to be the same size as the entrance area of the chimney, or can it be smaller because of a rain cover?
Does the chimney need a damper?
Would additional fresh air supply through a separate opening at the back of the firebox help?
Is there maybe a website with standard construction methods for open fireplaces, similar to what exists for wells?
I would immediately ask, hire, and pay a chimney sweep or fireplace builder, but believe me, such professions do not exist here, and I’m really far away.
So many thanks in advance for any basic information about fireplace and chimney construction.

the best approach is to contact the local chimney sweep master. If you do not know their name, simply look up the chimney sweep association online. There you will find the appropriate contact person.

@ ansgarm74:
Thanks for the great tip, "ansgarm74," but that really doesn’t help.
Believe me, there are no certified chimney sweeps, trade associations, Yellow Pages, or anything like that here.
