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!

  • Does my oven need a chimney?

    I've been wanting to build a pizza oven for ages and some time ago I saw an oven built without a chimney, just a simple dome with a door. My oven will be built outside, so I was wondering if the chimney is really necessary, or is it like a woodburner where the hot chimney sucks the air into the fire to get it really going?

    Ovens have certainly been built that way, but I'd have to say that they will not draw properly or create the desired venturi effect needed for complete combustion and really HOT fires. Add to that the inevitable smoke staining on the front of the oven. Build a chimney.

      Thanks Jim, I have struggled in the past with a woodburner which was fitted with a down-sized flue so I know what you mean. I have to say I quite like the smoke staining effect though!!

        Re: Does my oven need a chimney?

        PerryPizza, I have two neighbors with wood fired ovens that were built without chimneys. The biggest drawback I have noticed is not the soot staining but when they are being fired the flames (that those of us have going up the chimney) bend out and up the front of the oven. The most recently viewed one was at my neighbor's birthday party this past weekend. This particular oven was also built without any landing and was in my opinion quite dangerous to the unwary when firing up. The owner had stand guard to keep back the curious who wanted to get close and "see". He usually uses if for bread not for pizza and doesn't have crowds.

        Neither oven has any problem with airflow and they both were built with the entry to interior dome height proportion very close to 63%. One is sort of on the French Canadian lines where it's footprint is an oval and the other is like mine.. a hemisphere/dome.

          Its actually quite easy to get the staining effect with a chimney...

            Wiley,

            These ovens vent out of the front opening? That does sound dangerous. The title is "does my oven need a chimney" - I'm sure they would work without one, but I assumed that there would at least be a hole for venting. I discover something new here everyday....

              1000F heat and flames coming out the front opening? No thanks. Build a chimney (it's not too hard).

                Does my oven need a chimney? Do I need eyebrows? Build a chimney. I even added height to my chimney because it was close to the house, but it draws great, and I rarely choke on any smoke while it is heating up.

                  To summarize. Yes, you need a chimney. :-)

                  But seriously, you really do. It not only keeps smoke, fire and hot air away from your eyebrows, it also creates the draw effect that moves hot air effectively inside your oven, creating natural convection which makes your oven heat up and cook better.

                    Thanks for the responses, I will build a chimney!

                    The truth is I had always intended to, although I'd still like to hear from anyone who actually uses an oven without a chimney just out of curiosity. These certainly seem to be in the minority amongst the people on this forum! It is interesting that Wily has two neighbors who use this kind of oven, I can just imagine the scenario he describes...

                      I think it's like a car without a windshield (or windscreen, depending on your version of English). It still works, but the experience just isn't the same.

                      There is no upside to not having one -- the only reason to not have a chimney is either expense or effort.
