spark arrestor vs. chimnet vent cap - Forno Bravo Forum: The Wood-Fired Oven Community



New Forno Bravo Forum Feature

Forno Bravo Forum Community,

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.

To kick off our AMA feature, we have invited author, chef and master bread maker and host of Pizza Quest, Peter Reinhart, to be our first host! Peter will be in the Forum on Monday, February 15th, from 7:00 - 8:00 pm EST. If you are unable to be online during the live session, you can post your questions in the sticky post. Peter will answer those questions during the live session on February 15th. You can view Peter's answers to your questions as well as what happened during the live session in the session thread.

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!

    what is the difference between a chimney cap and a spark arrestor? are they one and the same?

    I think in practice, you end up doing both jobs with the same part at the top of your chimney.

    These are two separate jobs: spark arrestor to keep sparks from the fire from leaving the scene and causing a problem: chimney cap to keep the rain and snow from washing soot back down the chimney, but they are commonly built into the same part.

      A spark arrestor incorporates a perforated surface of some sort. The perforations job is to hold back particulates, this would include sparks. Some are woven metal screen and others are perforated plate. The screen offers more open area, is less expensive and has less affect on the draft. Some chimney caps incorporate this feature others do not, spark arrestors also are made without a chimney cap funcion

        HI Jlaw,
        I built a spark arrester on my chimney for no other reason that if the council or other authorities ever query my oven , I at least have done the right thing as I live in the foothills and in a fire danger area.
        I have never seen any sparks run up let alone out the top of the 10 foot flue.
