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!

  • Duravent Anchor Plate - Gasket required?

    I completed the flue on my oven today, and need some guidance on how to install the Duravent Anchor plate.

    I have the plate mounted on a flat 12 x 12 square of firebrick splits with a (roughly) round 8" cutout for the chimney. The fit is pretty good.

    I was planning to screw the plate to the firebrick using Tap-cons. I couldn't find stainless so am going with the blue ones.

    But do I need a gasket, or any sort of caulk under the anchor plate? Or is it ok to screw it straight to the brick?

    I used the Selkirk SuperPro pipe and mounting plate. They recommend putting a 1/2" bed of refractory mortar under the plate (I used Heatstop 50); then you torque the fasteners until you get a small amount of squeeze-out, so you know there aren't any gaps. I left the raised bead of squeezed-out mortar in place around the plate as extra protection against leaks.

      I used the Duravent plate and screwed it with tapcons,using a bead of Heastop 50 as the gasget in between.

        Two votes for mortar. thanks guys.

        In the interim I dug out the (rather generic) install instructions from Duravent, and they suggest high heat caulk. I think that would probably not last given the heat from a WFO. But I do have refractory caulk on order to use for my heat break and may try that. I'll see what the texture looks like and go with either that or the mortar.

        To be honest, afte getting this far with the oven, I am really tired of mortar
