Round Smoke Stacks
Comes in sizes from 6 to 24 inches in diameter.
Round stove pipe style smoke stack for exhausting the unburned gases and excess heat from the evaporator arch. Our smoke stack is entirely made from either galvanized steel or stainless steel and comes seamed together with a crimp on one end and a bead on the other for quick sturdy installation. All smoke stacks come in 3-foot sections.
Leader recommends that the stack on a wood fired evaporator be a minimum of twice the length of the evaporator (ie. 4x12 evaporator has 24 feet of stack), and 1.5x for an oil fired evaporator (in the example 18 feet of stack height). In all cases, the smoke stack should clear the peak of the roof and be unobstructed by any surrounding trees.
Why Buy Stainless?
Stainless steel has a much longer life expectancy than galvanized smoke stack. The highly corosive carbon buildup on the inside of smoke stack, mixed with moisture will break down the galvanized stack, and the excessive heat generated from a maple syrup evaporator will compromize the protective galvanized coating, exposing the raw steel. This will cause rust to begin to form and eventually holes will develop within the smoke stack. With stainless steel this process is extremely slow because the material is not coated, it has natural inhibitors to stop rusting and corosion. Stainless steel stacks will last 3-5 times longer than a galvanized smoke stack.
