I have a cowl on it already all be it a very old one.
So if I do the test with the smoke should it draw it up all the time or would more lb heat make it draw better and eliminate down draft?
got my chimney swept 3months ago. All was fire i bought a self lighting fire log and all smoke went up the chimney. I then added wood it was fine.
recently i bought some coal to test it out before winter.
i lit some wood and paper before the coal but there was smoke pouring into the house...
