Using an existing Chimney - 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!

  • Using an existing Chimney


    I am planning on installing a pre made pizza oven into my kitchen as I have just bought the house, what I am wondering is if I can use the existing chimney as a flue?
    At the minute there is an old central heating system in place which is being removed and the area is going to be my kitchen.

    Current look (soon to be removed down to bare brick) ignore the decor the room is bare now but I do not have a pic

    I plan to contruct a base for the oven to sit on so that I can slide the pre-made oven in.
    What type of pre made oven would be suited best and would a front prositioned flue by best to use in the origional chimney or whould I use a flue all the way to the top (10 metres).

    All advice welcome

    thanks in advance

    Re: Using an existing Chimney

    I think it's commonly agreed that a wood fired pizza oven needs the flue at the front, in the arch, to work properly. This makes indoor installations tricky usually, requiring quite a large space to work with -- not only the depth of the oven, but also an additional vent hood on the outside with a powered vent fan (separate from the flue) to catch stray smoke, especially on startup.

    The 'front flue' itself isn't typically a problem as it doesn't need to go straight up -- many custom build WFOs angle the flue as it leaves the arch so that it goes back over the dome and leaves the roof directly over the dome or anywhere else. The same can be done with a premade oven, I would think plenty of flue pipe companies make elbows etc that could route the flue to your existing stack.

      The answer to the question is no, you can't vent your oven into an existing flue , if it is used to vent another appliance, or fireplace...... if you are building to code.
