Smokestack help

Post by cparker2277 » January 21st, 2018, 12:59 pm

Okay guys I have a smokestack question . Iv plugged everything into the calculator and it shows a 35.5 inch smokestack. This smoker is going on a BBQ trailer so the smokestack is gonna be on a 45 degree out the back of porch. Because it's on a 45 instead of straight up will the length need to be adjusted?? To me the 45 could slow down draw a little. I'm sure I'm overthinking it but just wanted to make sure. Also what is the correct distance from tuning plates to cooking grate?

I start the grates usually about 3" above the plate. on the stack, I'm not sure it would have any effect. the rule is rise over run so as long as you have more rise (up) than run (horizontal) that should work. I would give it a shot and see what happens.

When I make something on a 45 like that which is supposed to have a specific elevation I use a 16 inch per foot of elevation rule.
Example 12" = 16"
In your case your stack would be 48" long and still be the right elevation.
