Ask Me Anything New Forum Feature

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.

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 to 8 inch round

    Building a 42" Pompeii and now planning my vent area. I recall on my last oven I think it was a 14 inch by 4 1\2" rectangular opening transitioning to the 6" in pipe on my smaller oven. Now with this bigger oven I am dealing with an 8 inch pipe and wondering what the recomended size of the lower rectangular opening should be before it transitions up to the 8 inch internal pipe? I was thinking the same size as my 36 inch oven as the door opening is the same size and just smooth it from the 14 x 4.5" rectangle to the 8 inch round.

    Is this ok or is there a better choice for the size on the rectangle part of the flue at the oven entrance?

    Thanks Wayne

    I've had a couple of glasses of wine and used a cheap calculator (doesn't have pi). It looks like the volume is good to go.

      Thanks Les

      I hope those were small glasses of Wine and I hope they were delicious!

      I will go with the 14"x4 1/2" transition to the 8 inch circle. Appreciate it!

      Should you sober up before I head to the job site tomorrow morning and you change your mind feel free to set me straight.

        Re: flue size to 8 inch round

        I'd make the transition as large as practical Wayne, to ensure at start up that all the smoke is captured and directed up into the 8" flue.
        My oven is a 40"Pompeii and has a large chimney void which works exceptionally well. Pictures are on my build posting.
        However, the deeper you make it, the further you will need to reach into the oven.

        Prevention is better than cure, - do it right the first time!
