4” chimney ... is it big enough?

[fox]

Hi guys, I am looking to buy a cast oven from the U.K. but there is not much choice with only two options that I can find!

There are several nice looking multi component ovens for sale but they are made fro insulating materials... I don’t really get that but it seems to be popular!

Anyway the one I most like the look of in the Vitcas high mass oven however I have a concern with the chimney opening size as it is only 4”.
it appears they use the same chimney on all their models .
so my question is ... will a 4” chimney be ok on a 32” oven?

At least with Forno Bravo oven plans, the recommended chimney size for a 32" is 6"ID. There have been several cast ovens built or being built by UK currently. Look in "Other Oven Types".

Nick JC did a nice job on his. It this section, there are list of material suppliers. I thought you already built an oven?

Thanks I will have a look.
Yes I built a mould and in fact made 6 ovens!
Unfortunately my mold has taken a beating and would need a lot of work to get it in one piece again ha ha.
The last oven I made in the mold got really stuck and I had to break the mold to get it out, my fault for being complacent and not waxing it properly.
Anyway I have have another friend wanting one built so I thought it would be easier to buy one than re build the mold
I just assumed there would be a choice of ovens to pick from but no.... I enquired about a FrnoBravo model but I was told to contact this guy in NZ as regarded U.K. sellers but he (she) did not reply.
There is one other choice but I was not so keen however it does have an 8” chimney opening.
