Believe me, those weren't my words. I find the level of knowledge and will to help here invaluable. I was less than happy to hear those remarks myself although sort of expected them. We're all human and make mistakes but it takes a big person to admit one and correct it and unfortunately, this manufacturer failed that test.

Found a couple ways to reduce smoke. Biggest idea is start the fire slowly and build it up.... avoid using paper or cardboard... use kindling at first. Use the door on an angle with the opening being about 3 to 4 inches to allow draw and force smoke up the chimney without suffocating the fire. Preheating the flue helps at first as well.
A good hardwood like fruit wood (we use apple/cherry and apricot) helps allot.... no green wood and avoid sappy woods. I increased the length of our chimney and that helps draw the smoke. Have seen indoor wood fired ovens with a vent placed in front of the opening to draw any smoke that escapes out of the oven. Would be a shame not to use the oven.

Thnx.
My curiosity was getting the best of me. It looks like NYC couldn't get satisfaction from manufacturer or couldn't make his original oven work. I think I may have the same oven as his. I have not installed it yet but spent a great deal of effort making a structural support for it. I'm now nervous that I may be heading down a similar path (of disappointment). I'm hoping to get a bit more feedback prior to throwing in the towel on my current purchase.

Anybody with experience or knowledge of the Stone Age WFO I'd appreciate your input.

Thnx,
GWN

I responded to your post on another board saying that I thought the oven was a joke. I didn't realize you had already purchased yours. Sorry for being so blunt. I agree with Mick that there is stuff you can do to improve it.

What I don't know however is whether or not the width to depth ratio is such a problem that it will never draw correctly. In looking at the plans, it appears that once constructed, the oven chamber will be 41 inches wide by about 36 inches deep. I have READ (no personal experience) that with the oven being wider than it is deep, can not be made to draw properly. I would do research to see if that aspect is as significant as I have heard it is.

Other than that, adding the insulation and plugging the existing chimney in favor of a proper flue chminey forward, will help.

I'd make sure I got the names of some existing customers and talk to them to see how it draws/works.

Thnx Bill, I will consider these recommendations. I'm in process of checking with existing owners/users.

Question for you or others: The unit has a 3" high heat concrete floor slab. This was going to be placed over a 3.5 " concrete support slab. With all the insulation advice, I'm considering not using the 3" floor slab that comes with the kit and substituting 3" of rigid insulation under 3/8" cement board with refractory (the cooking surface) bricks over all.

I can't do both at this point as the surrounding structure is built & elevations are critical.

Thnx

Don

The one option I was attempting to convey was to substitute the conc floor slab for insulation covered with cement board. the bricks would go on top of this. this would not change any heights or ratios.

Responding to Micks post I checked the dome ratio and as it stands (as designed) is 0.58, which according to Mick's post, is too low. If I put the bricks inside the oven walls instead of under the walls the ratio would be much closer to ideal. From what I read, I just have to be sure this an expansion joint (or space) at the wall/brick to avoid complications with heat expansion.

I have lots to think about. I have to talk to some folks who have /operate one.

it has a 3" concrete floor slab as part of the kit. High heat resistant I'm told. it also comes with the appropriate fire bricks to place on top of this. The assembly plans are not 100% clear as a picture shows all of the concrete pieces mortared together PRIOR to installing the fire bricks, yet the drawing shows the bricks UNDER the walls of the oven (which would mean they are laid prior to fitting the arched dome (walls) on top. I will have to get clarification from manufacturer.
