How to improve venting for an existing built-in oven?

"Gulf" said not to force the smoke mechanically - could you say more about this please?
Is it because of the danger of forcing smoke into another part of the shared flue?

Hmmm, I'm struggling to do this from memory, but hopefully I'll be there on-site in a few weeks.
I have some clear actions when I get there:
1. check that (some) smoke is in fact going up through the slit
2. check the size of the slit
3. look into building an external flue

I'm in the USA right now, but I seem to remember the chimney does carry some smoke (i.e. I can see smoke coming out of the chimney on the roof), just not all of it - that suggests the chimney is (at least partially) clear.
I do need to get up on the roof and test it when I get there.
Any suggestions for an easy test?
Not sure how much the pics will help.
There's a pic of the setup - oven + pizza oven built in to the house.
The chimney goes up through the roof, but it's not shared with any of the house chimneys.
Then there's a pic of the oven - there's no vent or flu inside the oven, just a narrow gap immediately behind the metal doors, about half an inch.
If there were a flow, I can imagine the smoke being sucked up through that slit on its way out of the oven. I'm thinking I just need to get that flow moving.
Thanks for the detailed reply. Looking at an enhanced view of your photo. It seems like the smoke is sucked up into a much bigger "gap" than "half an inch" Please confirm.
Regards,
Mark

My opinion is that you will need to build/install another chimney/flue just out side the cooking chamber of the "pizza oven".

The Italian place has an outdoor pizza oven and regular oven side-by-side, both venting to a small chimney in the roof.
We use local wood for both ovens, and there's a huge amount of smoke - when my nephews visited from the UK, they wore snorkeling masks while cooking!
Is this just a matter of getting the right wood? The right draw?
Is there some way to force the smoke up the chimney without investing in a large (expensive) chimney fan?
Thanks in advance for any tips, pointers.

Hi Sbuxton,
Welcome to the forum. Sharing a chimney/flue with multiple sources usually leads to problems. I'm a little concerned about the size and type of shared chimney you have. Flues for conventional ovens and stoves are really just vents to exhaust cooking smells and carbon dioxide if they are gas fired. A little more information and pics may help. But, DO NOT add any kind of forced exhaust vent to the wood fired oven since it is sharing a chimney that is attached to the house.Last edited by Gulf; 06-19-2021, 07:06 PM.
