Right!!? Bad mouth everyone and walk away.... really helpful and productive... Isn't part of the reason for a forum like this is; one, ask questions, and two complain or critique products to see what others think of the product and or help others with said item or issue....? Maybe I'm way off, but probably not. MightyWhitey
Man it looks like she has (4) 30" sections which would be ten feet of pipe.Pipe may be too short to produce a good draft.Would be nice to see where the roof peak is in relation to the chimney pipe.I thought I read somewhere that Blaze King stoves need 13 or 15 feet of chimney to draft right.Her stove may need a certain height to draft well.Which ever stove she has.
Would have to go back through this thread again, but pretty sure it's also 15'... Edit: Yes, here...Draft Inducer
I see four sections of pipe above the Tee.If those sections are four foot sections she'll have 16 feet,If those section are 30 " or 36" she only has ten to twelve feet of pipe which would be too short for drafting.If it is 16 ft she'll probably need another length of pipe.
IIRC this is Supervent pipe...so those would be 36" (+24" & 12" up top there) so 12' outside, plus the pipe height inside too...minus (2) 90* elbows (might be one 90 and (2) 45's now?) so yeah, the effective chimney height is a little short IMO...
I'm testing the vacu-stack now so far it didn't change the draft or help with cold startups draft, but I need more time. Will increasing the chimney height help with better draft (smoke spillage if you dont warm flue) on cold days during cold flue startups? Or just better draft during the burn to prevent smoke spillage from door? Going to try adding a extending chimney section and inside double wall after that. Thanks for the help.
Plenty of sites on how chimneys work. Read #3 from this one. How Do Chimneys Work & Why Are They Important? | Long Roofing None of my stoves have double wall inside of the house....with the exception of that little bit before the ceiling. I have always run single wall pipe to that point. Cold start ups are a condition that has to be overcome....typically by building small hot fire first...like just some paper crumbled up.
I should have added that only one time in my years of wood burning, the chimney height was inadequate (or so I thought). Turns out, the unit needed more combustion air. An OAK would have solved that problem...heck, even leaving a basement window cracked open would have solved that problem! But, I got rid of that new stove anyway. I don't think it was even a month old!
