Have you added a adjustment flap as was shown above?

Fuel mix ratio is a key part of any/all efficient combustion operations. :idea:

I have the same problem: coal builds up on the grate, and the stove doesn't get hot.

I have two Alaska stoves. They're on different chimneys. One stove (in my "front room") burns hot as can be - it works absolutely fine. the other in my "back room" - not at all, especially when it gets cold outside. The colder it gets outside, the worse the "back" stove performs. When it's warmer out, the "back" stove burns really hot.

My problem began after I installed a stainless steel liner in a chimney that was built around 1940 (best guess). It's made of brick but that's all - no liner (until I put the stainless liner in it).

Most people I talk to say there's too much draft. Unfortunately, I can choke the draft just about completely (using a manual damper) and it doesn't help. I restrict air intake - it helped but only a little.

I really wish I could figure out that the problem is.

Oh, I bought a whole new burner assembly. I put it in the front stove and took the old one from the front stove - because I knew it was working perfectly - and put it in the back stove. Even with a known, good burner assembly, the back stove still produces little heat, especially when it's cold outside.
