  • chimney pipe/stove pipe questions

    What size of pipe is recommended for the 42" oven?
    What about triple wall chimney pipe - will that work? It iis stainless steel.
    And how long should it be?
    It's "Metalbestos...Type SS-II"
    and it's 30" long. Could I use this?

    Cecelia,

    Triple wall stainless steel will work fine -- it's a tad thick for what you get, but it will work.

    What is the inside dimension? You want 8".

      I can get it for 35 bucks! I am waiting to find out if the inner dimension is 8" - keeping my fingers crossed!

        What about chimney caps? I am using a clay (terra cotta) chimney - actually, an 8" thimble. I am assuming I'll need some sort of cap but what purpose does a cap serve and what do I need - as in MUST have? Do I need downdraft protection? Or just weather cover?

          Carbon from your chimney will wash down the flue and end up on your landing if you don't have a chimney cap. It may help with downdrafts, but that's the main problem if you aren't providing a critter barier for an indoor oven.

            And a spark grate of course.

              So nothing fancy is required? Taken to a simple extreme, I could just place a non-combustible cover on top (above) the thimble, slap on a screen grate thing and, voila?

              Sorry for the simple questions. I just need to understand why I do things, what I need to accomplish, before I move ahead. Once I understand I can make decisions based on whim and caprice if I'm so moved. So thanks. This oven building can get obsessive and this forum is just a brilliant collection of enablers.

                Well, i didn't get the chimney pipe - oh well. I'll keep looking - but it's kinda expensive at FornoBravo - Is it that expensive everywhere?
                Where do you get the terra cotta chimney?
                Could we build a chimney out of brick?

                Am I correct in saying there doesn't have to be an opening with a vent at all - of course the smoke would end up coming right out in your face, I suppose - not much different than my junk electric oven at the moment!
