Insulating the flue?? - Forno Bravo Forum: The Wood-Fired Oven Community



Photo Galleries are back! Instructions below.

Dear forum users,
Thank you for your patience with the Photo galleries. We've got your galleries online!
We have finished writing a custom script to migrate the PhotoPlog to vBulletin5’s albums.

Unfortunately V-Bulletin killed the "Photoplogs" in their software upgrade which was unforeseen and we're the first development group to have written a script for getting the galleries back... that said, it took some time to reverse engineer the code and get the albums to move over seamlessly!

Forum users will be able to access their “PhotoPlog” images through their user profile page by clicking on the “Media” tab.
They will also be able to browse other albums by going to the albums page. (On the forum site, there is a link in the black bar beside “Forums” to the albums.)

In order for users to create an album please follow the steps below.
1) Go to user profile page and click “Media”
2) Click Add Photos
3) Enter Photo Gallery Title in the first field
4) Click Upload or Select from Photo Album to add photos
5) Click Post
6) Once posted, the album will be created as a “Topic” on the albums page for the public to see. The topic title will be the “Photo Gallery Title” they created before uploading their photos.

To create this migration path we used vBulletin5’s default album structure. Unfortunately, it won’t work like the “PhotoPlog” but is an album/gallery component on the forum now.

  • Insulating the flue??

    Hi all,

    Have been on the site for a while now but have only just recently been able to work on the WFO. Would like to say a quick thank you to the forum and all the guys for being a great source of advice. I could not have gone this far without the help of this awesome community!!!! you guys rock!!

    I have just finished building a 48" dome and am about to attach a 6" galv flue on top of the vent. I have a guy making me an 8" clay flue to cover the 6" and have half a bag of vermiculite left over from the insulating slab. Can I / should I pour this loose between the 6" and 8" flues??

    I live in quite a rural area and would like the oven as insulated as possible to reduce any fire risk. Will also be putting a spark arrestor on the flue and a stainless mesh door for firing the oven.

    Any comments would be appreciated.

    Your plan should work fine, except the galvanized stove pipe liner. First - ofgassing hot zinc is not something you want around food, second - it's likely to rot out from corrosion is two or three seasons. I'd spring for stainless pipe here if you can get it, if not, get the black stuff they sell to go with woodstoves.

    A final consideration: six inch is a small flue, and 48 is a large oven. If you want to avoid smoke leakage on startup, you may want to switch to an 8.

      Hi dmun,

      Thanx for the reply.

      Would it be better just to use the 8" clay flue?

      Would this get too hot? or is a double flue just overkill?
