Chimney Placement on RF Conversion

Post by DDave » January 8th, 2019, 9:17 pm

Now that this smoker is done

Image

our next project at the high school is to convert this guy to a reverse flow.

Image

Image

We will be ditching the old firebox and chimneys and after it is converted it will be put on this trailer.

Image

I ran the numbers through the Pit Calculator and have come up with a chimney size of 6.5" in diameter by 34" high. But I have some questions about placement.

Since the doors have already been cut to the center it's not going to be easy to place the chimney in the center on top.

Image

There's not much room on the end either.

Image

So I figure our options are something like . . .

A:) Place it behind the cut of the door which will put it off center slightly and as close to the end as the "flat" part of the tank allows.

Or

B:) Something like this.
Image

Or

C:) Centered but having one side longer if necessary to accomodate the shape of the tank.
Image

Which would you recommend?

This stack location is like one of your examples and works very well. Stack is 8" and oversized for pit (free pipe). Image

Either way will work. Looks like a fun project. I'll bet that little bitty fire box had a hard time keeping all that hot.

A or C....no real difference either way as they are both mounted high and will vent the top of the chamber. I tend to be pretty ocd so personally like the look of a centered stack better so would lean toward ‘C’ for just the appearance.
