What size(diameter) stack on a 30"x10 ??

[mrnorthshore]

Can any one tell me what size (diameter) stack should be on a wood fired 2 1/2 x 10 evaporator. It came with a 12" metal drain pipe for a stack. I just got 20 + feet of double wall stainless pipe for free from contractor,but the only thing is that its 11 inch inside diameter. Can any one tell me if this will be a problem to drop down in size from 12" to 11"?? Thanks

I think you would be fine with 11". The top of my base stack on my 30" is 13 1/2", so I had to have a collar made to go from it down to 12". 11" is'nt much smaller than 12". You would'nt notice a difference between the two I'm sure.

Ours is 12", but like Bucket said 11" is quite close. Might want to go a bit higher (more pull) than you normally would have.

The Leader catalog lists the following stack diameters for their line of 30" wide rigs:
Leader = 10"
King = 10" or 12"
Grimm = 14"
