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!

  • Duravent chimney question

    I've noticed different ways of installing duravent chimneys in combination with a stucco finish. Mostly, they seem to cover the chimney, at least a bit.

    My neighbor is a retired fireman, who says I shouldn't stucco the chimney in place, but instead leave the base accessible for future removal. He says he's seen several of the double wall chimneys burn out over the years, requiring that they be replaced.

    Personally, I'd like to bury it in an inch or so of stucco at the anchor plate to make a smoother stucco transition from the top of the dome to the entryway.
    Now I'm thinking about coating it with vaseline, oil, or some other separating medium to prevent the stucco from sticking to it.

    Anyone have recommendations on this issue?

    Many thanks!

    I'd bury it George. I'm going to do the same thing. ( I should have more time and MONEY now that the Holidays have passed.)

    It's not like your going to be firing it every day.

    I think it will last for years.

    But that is just my opinion.

    How's everything else going?

      Re: Duravent chimney question

      Everything is going great! Thanks for asking.

      That's a great observation regarding the comparative low use of the oven. You're probably correct that it will last a long, long time......

      Still, I think I'm going to wrap the chimney in plastic wrap then place the base coat of stucco, then once it has set, remove the chimney and plastic wrap, and replace the chimney. I'll do the finish coat of stucco directly against the chimney, which should be easy to break out and repair if I do ever need to remove the chimney.

      Thanks for your help.

        BTW.

        I am going to run chicken wire around mine, then mortar, and then the stucco finish.

        I think this will help improve draw....

        I think a little mass will help to keep the chimney heated up.
        Mine is just 18 gauge steel, single walled, so it heats quickly, but cools quickly too. So when the fire burns down, the smoke likes to hit me right in the kisser.

        Anyways..
        If the metal corrodes and rusts, then I guess the mortar becomes the chimney.
        Or maybe the old one will come out in pieces, and a new one slid into place.

          Sounds reasonable. I figure we built 'em, we can always fix 'em.

            That is my thought exactly. If, years from now when we are REALLY old, and the transition thing corrodes, the 1" of stucco will be the chimney. And if you still think you want to replace it, it won't much matter that it is wrapped in plastic or vacoline because it will be disintegrated anyway.
            I say cover it with stucco...the more the better. But I'm just thinkin'. No real knowledge on the subject.

              Dusty, I'm full of partial truths and no real knowledge. I value your opinion. I've seen your work. Thanks for the reassurance.
