The back of the Corsair evaporator comes with a perforated knock-out and studs to make installation of a new blower as quick and effortless as can be.
Using a Forced Draft Kit allows you to burn less seasoned / larger pieces of firewood. It also does a great job helping to consume the firewood complete. At the end of a boil, you will see very little coal in the firebox.
When purchasing the entire Forced Draft Kit (includes both the blower and the grates), there is a discount as opposed to purchasing each separately.
