I've only had this stove for less than two days now, but my question is: Is there anyway to know if the primary air slider is actually doing its job? The slider sits in a welded casing so its impossible to see what going on inside. I've yet to see a difference with the slider all of the way open or closed. I can feel the air entering in the intake hole in the back of the stove. But when I close the slider and keep my hand there at the same time, there appears to be no reduction of airflow. It seems once a fire is going and the slider is closed all of the way there is no way to further cut the fire down. And if a fire is dying out, opening the slider doesnt seem to boost the flame like I would expect it to. I'm wondering it the slider is suppose to sit inside a little track of sort. I'm able to take the slider handle and push is downward and a few inches. So if I "bounce" the handle down and then back up. I can hear what should be the baffle or damper that is hooked onto the primary handle lever. It all seems so loose, I can move the primary handle right and left also and hear the baffle clang against the sides of little chamber. Maybe its normal, but being it all seems so loose, it makes me wonder if it somehow fell out of some kind of track. I was digging around for a schematic drawing of the stove but I wasnt able to locate one. I didnt get a manual, being the unit was a display model, and I didnt see one on the online manual.
