Flue size for an indoor pizza oven - Forno Bravo Forum: The Wood-Fired Oven Community



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!

  • Flue size for an indoor pizza oven


    I'm building a 36" pizza oven indoors and there is already a heater of sorts on site connected to a flue that is approximately 10ft high.

    I wonder... would it be unwise to use that flu for pizza oven purposes?

    Otherwise, what is the cheapest possible type of flue I can purchase? Must it be stainless steel or would a simple wood stove flue suffice? The pizza oven will only be fired a few times this summer so we don't need a permanent solution.

    Thank you for all your help.

    It would not be OK to share a flue. What size will depend.

      Thank you Tscarborough. I don't intend to share the flue. I will remove the device that is currently there and build a pizza oven in its place. Is it not ok to then attach the flue to the pizza oven?

        I see. If it is the correct size and design (triple walled), then you could use it. The size would probably be 8" or larger for a 36" with a long run.

          I think, from the looks of it, it is single walled but i'm not on location at the moment to verify. Does it need to be triple walled for safety purposes? Will single walled not be safe?

          So, if I understand correctly, the longer the flue, the larger the diameter? I imagine a 6" diameter will not draw well?
