Dome Installation Video - Casa / Premio / Modena

Hello,

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.

  • Slip Joint or not?

    Hi Out there,

    I will be building an outer arch out of Bullnose bricks 9". I'm leaving the half bricks out to create a toothing which will be filled with 3" of blanket 1" of vermiculite/fondu then 3/4" of render 41/2" of the Facade bricks will overlap 41/2" of the firebrick inner arch should this overlap be a slip joint would appreciate any thoughts.Bricks

    The outer arch looks from the pic like it will be in contact with the heat and flames?
    If so it will crack with the heating and cooling cycle.

      Hi Bricky in Oz,
      I'm thinking the same. Perhaps a 5mm gap between the to arches as both are selfsuporting.Or because its the furtherist from the fire a bed of fire clay or ramming puttey between the two could work.bricks

          About 6:1 vermicrete will work well too.

              Hi Bricky in Oz,
              Just thinking that if i cut a channel into the internal and external bricksto take the rope it would act as an anchor and a great seal still allowing say a3mm gap to difuse heat transfer to the facade. Bricks

                I just use Portland. It is in a slightly cooler area and seems to work ok. Fondue is a bit of an overkill IMO when used outside the main oven. It is also way more expensive.
