I have made a few comments here and there about the ACC stoves that came out from Quadrafire. Everyone seems to be curious and I got some more info so I thought I would post it.
It has two air control levers on the right of the stove. The one on the bottom is dual function. Sliding it all the way back engages the ACC timer and opens both the front and rear air. The front air is controlled by the timer and is often called the "startup" air. The read air flap is controlled directly by the lever and is the primary air. After engaging the startup air you just slide the lever forward into the range noted on the sticker (low / med / hi ) for different burn rates. The second air control handle is just a pie piece welded to the lever. It slides over a cutout hole and controls the air flow to the air wash in the front of the stove. A little air from this will also bleed down into the front "startup" air hole by design. The manifold tubes work the same as always in the Quadrafire stoves. There is a channel that goes to the back bottom of the stove and the tubes draw air from there. The stronger the draft, the more air will come through those tubes. If an OAK is hooked up the manifold tubes draw air from that.
