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.

Dome Installation Video - Casa / Premio / Modena


For many of you who bought a modular oven, you may have asked how we put the domes together when we build them. For those of you considering one of our ovens, we shot a video to make your install easier.

Check it out on our You Tube Channel.


If the link doesn't work, simply go to You Tube and type Forno Bravo Channel. The video title is How to Set your Forno Bravo Oven Dome Pieces.

Thanks for participating in our Forum. We will have more video content available soon.

  • Why double walled chimney pipe?

    I've got most of my framing done around the oven and getting ready to start on the roof. I have an 8" diameter steel pipe with a damper that came with the oven and was planning to extend it with double walled pipe and spark arrestor. Looking at the dimensions of the double walled pipe and allowing for clearance, it seems to me that it will look a little oversized (too wide) for the look I was going for.

    Is there a reason why regular single walled pipe can't be used? Are steel studs and HB considered combustables?

    Hi Dan,

    As long as you are doing to insulate around your single wall pipe, and of course set it back from combustibles, you can use single wall steel pipe. Metal studs and HB are not combustible, though you will want to build an enclosure around the pipe and insulate it.

    In fact, the Casa and Premio vent pieces are designed to take single wall pipe (in cm's not inches), without an adapter.

    The advantage of the double wall pipe is that all the insulating work is done for you. It's easy to just snap it all together, and know that it is UL approved and that is will stay hot on the inside (which keeps it clean and drawing well) and cool on the outside. That said, it is more expensive.

    Hope this helps.

      Thanks James,

      I realize the benefits of the double walled pipe, but esthetically it just seems too wide. I'll try drawing it up with a chase around it (although it will be wider), it may look ok.

        Can anyone tell me - If I used single-walled pipe, what kind and depth of insulation would I need in order to brick in around it?

          I would think that an inch of insulating blanket, or two inches of vermiculite concrete would be about right. Remember, single wall pipe is for freestanding ovens only. Code won't allow it for use in structures.
