    Default Sugar shack smoke stack question

    So the sugar shack smoke stack consists of duct tubing made up of a 2í horizontal section, elbow, then up 10í vertical. Problem- The system is outside of the shack hence exposed to the elements and the horizontal piece rots out every season or two. Any suggestions on how to protect it? I was told to drill a drain hole. Thanks in advance! Ps- I no longer use the pre heat coil feed tank system)

    It's hard to see it clearly in the picture. Are you saying precip. is coming down the smoke stack and rotting the horizontal piece from the inside? If so, a stack cover will take care of that. A cheaper version is to put a bucket over the top in the off season or when you are not boiling. If you use a metal bucket you can put it on when you are finished boiling.

    for many years the end of our arch was outside the shack we used old metal roofing to make back wall of the shack next to the stack. Our chimney was made out of 1/4" steel material though, it collected scale but never rusted out. it was outside until last season we build a new arch and moved the whole setup just inside the metal roofing so it's out of the weather. re used the whole stack just cut the width down. Still need to do something about a roof jack though.

    Thanks woodville! Yeah the pic sucks. I do cover the stack after use but the moisture is still finding itís way down. Iím not sure if itís rusting more from inside out or outside in. As Iím now thinking since Iím not using the pre heat and rear tank feed any longer, Iím thinking that there area can probably be more enclosed by boxing it in with cement board or maybe corrugated roofing material making sure thereís ample space around the stack.

    I think the heat rusts out the thin wall duct tubing. Easier/cheaper just to replace it every couple years than trying to make it last longer.

    I agree. I use single wall stove pipe and I have to replace it every other year, inside and out. The heat just breaks it down. The only way to avoid it is go stainless or heavy gauge.
