New Forno Bravo Forum Feature

Forno Bravo Forum Community,

You will notice a new forum at the top of the main page called, "Ask Me Anything". This forum will be used for live one hour "Ask Me Anything" (AMA) sessions hosted by people who are knowledgeable in different areas pertaining to wood fired ovens. How it works:
- Each AMA will have a "sticky" thread where the community can post questions they would like answered during the live session. This will allow everyone to participate even if you can't be online for the live session. These questions will not be answered by the host until the live AMA; if you need an answer quickly, you should post it in the appropriate Forum area for the community to respond.
- Another thread will be posted for the live AMA. Registered users who are logged in during the live session can interact with the host by asking questions and receiving responses.
- The live thread will remain in the AMA forum to view after the session.

To kick off our AMA feature, we have invited author, chef and master bread maker and host of Pizza Quest, Peter Reinhart, to be our first host! Peter will be in the Forum on Monday, February 15th, from 7:00 - 8:00 pm EST. If you are unable to be online during the live session, you can post your questions in the sticky post. Peter will answer those questions during the live session on February 15th. You can view Peter's answers to your questions as well as what happened during the live session in the session thread.

We hope you enjoy this new feature! Please let us know if there is a topic that you'd like to have as an AMA and we'll look for a host!

Dome Installation Video - Casa / Premio / Modena


For many of you who bought a modular oven, you may have asked how we put the domes together when we build them. For those of you considering one of our ovens, we shot a video to make your install easier.

Check it out on our You Tube Channel.


If the link doesn't work, simply go to You Tube and type Forno Bravo Channel. The video title is How to Set your Forno Bravo Oven Dome Pieces.

Thanks for participating in our Forum. We will have more video content available soon.

  • Oven vent

    As a newbie I have to ask... Why do I need a chimney vent? I noticed the traditional ovens did not seem to have them and just featured the door opening.

    Well put mick.....I agree totally except the bit about smoke in the eyes. My mates got a tunnel oven internal chimney which you cap off after flashing up the fire. The heat coming out that entrance is real hot. More than one person has lost their eyebrows putting wood in that oven!!!!

      Thanks very much! My yard is rarely calm so I will include one in my plans.

        Re: Oven vent

        I have a vent question for the group. I am designing my WFO to look like a fish with the entry being its mouth, the oven hump being its body and the tail at the rear to be added. I would like to vent my WFO via the usual location behind the entry. I would like to route the vent using 6" round stainless steel flex tubes over the oven hump and exit toward to rear via a fin as a cosmetic. The fin-vent exit is 12" above the top of the completed dome and 18" above the vent opening. Question: Would this design work? How much rise would I need to get a good draft given a 36" diameter floor, 19" dome height (using catenary curve equation), and 12" high entry. I have looked at the flow equation that many are using but it does not allow this variation. Thanks for your interest and response.

          Re: Oven vent

          Thanks for the response. No, i have yet to purchase the hardware. I am just a few dollars short and three miles from getting it from a specialty shop here in SD. I came across a thread ref the ratio of vent opening area to door opening area should be greater than 10 percent. With a 6" round vent to a 12" hemispherical door door, my ratio comes out to 36 pi / 72 pi equalling .5. I thought sufficient, but I may have misunderstood what the ratio should be. I can go 8" round. This will give me a .89 ratio. Comment?

            Re: Oven vent

            I agree. If I go from a large vent area to a smaller vent area the flow velocity does increase ... per aerodynamic theory. There will be flow with both 6" or 8" diameter pipes with the 6" at much higher rate of flow, Q dot. I am ready to go either way given empirical data from completed WFOs. I could also use a single walled vent piping from Home Depot to test the flow parameters at different diameters and at various venting angles before I finalize the vent system. Hope more responsescome in timely enough. Thanks for your response.
