Did you say BARO ? that may be your problem. Does YOUR stove call for a Barometric Damper? Dampers kill draft to some extent even when closed. My stove would go out if i had a damper in the flue stream. Others can chime on this here but I don't know of any coal stoves that use dampers.brandonh98 wrote: ↑Fri.

The real test looks like it wont be until next weekend when temps get into the 40's again.
Draft issues due to chimney cap?

You don't know of any coal stoves that use a BARO ???
The OP's unit REQUIRES a BARO.

Well i can always learn something new. It certainly would make my stove even harder to keep lit than it already is.windyhill4.2 wrote: ↑Sun. Mar. 04, 2018 1:12 pmREALLY ??????????????????

Thanks to some members on this forum I gave my chimney some much needed attention. Put on a new crown and a new cap. Removing the old cap made a huge difference in draft. I can easily run in 40+ temps now. I still think I would have issues into the 50's though.
I also replaced all the gaskets on the stove when I shut it down for the summer. Hopefully this will also improve the draft.
Thanks everyone for the inputs.

The Cap should not adversely affect your draft but Any rain falling down the chimney without it certainly will or at least that has been my experience
I also have a 16x16 block chimney with an 8" terra cotta liner

Any cap that hinders the Bernoulli Effect will also hinder draft. A simplistic verbalization of the Bernoulli Principle goes like this: When velocity is high pressure is low at an angle of 90 degrees with respect to the flow, and when velocity is low pressure is high at an angle of 90 degrees with respect to the flow.
Notice in the video simulation of a chimney that velocity across the top of the chimney (and thereby at a 90 degree angle to it) enhances the draft by reducing pressure. Water can be used to simulate a chimney because the same principle works for both water and air.
Daniel Bernoulli quantified the mathematics behind his principle in 1738.

I had more draft with caps than without, kinda strange, but it hardly matters as I have such a strong draft either way. Its a wide open windy area. Unscientific of course, just using my manometer and eyeballs.
The wind got both my caps long before coal fumes did. Even ripped off the one that screwed onto my stainless chimney and I had a screw thru it to hold it in place That constant wiggle breaks them and I gave up.
