detailed Vent / chimney photos - 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!

    Sorry about the newbie question.

    I have pretty much figured out all the details except the vent, thanks to this forum and photo's. Am I correct in assuming that the exaust leaves the chamber to reach the vent? I would really appreciate a photo or description of that constuction. Most of what I can find here is the chamber constuction. Also, if a door is used, wouldn't it have to be on the outside of the vent?

    Buongiorno Les,

    Yes, the hot air leaves the oven through the front door, and is exhausted through a vent above the front door. Air is breathed in through the lower half of the oven chamber opening, drawn in a circular pattern through the oven chamber, then pulled through a vent above the door opening. A round oven design draws very well, and smoke is typically not an issue.

    The door is left open during fire-in-the-oven cooking, and closed for retained heat cooking.

    Hope this is helpful.

      Just to clarify, a door is used for retained heat cooking, and is inside the vent. Otherwise, it would pull hot air out during baking. In retained heat cooking the fire is raked out of the oven in to another container.

      The form of the vent opening is usually some sort of funnel. The easiest method of doing this is to have a vent welded up from heavy gage sheet iron:


      You can also make up the vent funnel by cutting fire bricks. They come in "splits" or half thickness bricks that are easier to cut into shapes.

        I made the vent, just by using firebricks. It was an easy work and I like the results.
