I had a load going, closed the bypass and cut the air back to about .3. I had the floating flame at the top of the glass, but the combustor wasn't glowing. I went outside to take a look...fairly heavy smoke coming out of the stack. I went back in and opened the air to about .8, got more flame, and the combustor kicked in. Then I cut the air all the way back. Combustor got to glowing brightly. No smoke coming out.
What gives? I thought the combustor was supposed to be burning any available smoke, no matter what was going on in the firebox. I also thought that just because the combustor wasn't glowing did not mean it wasn't working. Apparently that's not the case here. One reason I bought this stove was because it is rated low in emissions. I don't want to be bothered with having to make sure that the combustor is doing its job, and adjusting the burn if it isn't. Any ideas? Any Keystone burners had this problem?
