Draw Collar
I have been fighting a downdraft problem for years , at times so bad, it was even impossible to to get a draw going . My stove is in the lower level of the house with a 20' flu, in a cold outside chase .Tried the Draw Collar , let it pre-heat for about 15 minutes , had the stove loaded and ready to go before hand , and it worked beautifully, " As Advertised " what a relief to know I can now get a fire going under conditions that were difficult, at best, before.Thanks for a product that works!! Here's hoping it has longevity .
