Not sure I understand why the smoker would not be able to produce enough heat? I have seen one in person but didn't look at the size of the fire pot. I would assume it would be sized according to size of the unit.

I was not questioning the Yoder. I love mine, YS640. I was following the idea of converting a stick burner to a pellet burning unit. I feel lowering the exit from the cooking chamber to below the grate would go a long way towards making it a more efficient.

here's what I was thinking, please forgive the sloppy image, but I hope this gets the point across better than my initial post.

PS I concede PG500 has similar capabilities.  Thanks for sharing that.

Look at Louisiana, Same principle, Just set up differently. The sear station/fire pot is located on the left side of the barrel. Close it up for smoking & there is an optional cold smoker bx you can buy that mounts on the right side of the unit.
