I have a Country Comfort model cc160, the smallest model that country comfort made, at least to my knowledge. I have used this stove all winter for 20 years now. These stoves were made very very well made , heavy wall steel. Mine has the blower unit and it will heat my well insulated house with no problem. I close off the bedrooms I am not using, so this stove is heating about 1600 sq. ft.. I have had to replace 3 bricks in 20 years service, and I just replaced the Roxwool insulating blanket on top of the baffle bricks. My stove is a small fire box, it lights off real fast, drafts well, and gets up to a hot temp. quickly. the secondaries lite off fairly quick, I think because of the small firebox. These stoves are a real work horse, and they look good too, clean it and paint it. Your stove actually looks to be in real good shape, from what I can see in your picts. I saw no signs of over firing, but be sure to inspect it very good. Buyer beware. My stove only has 2 controls, not counting the blower fan switch, Primary Air,, and Air Wash for the glass door.. I do not have an O.A.K. but this stove drafts well enough without it. These are a jacketed convection stove, so a fan does help the stove put out the heat. This is all I can tell you about my stove, I hope you have as good use of your stove as mine has given me.. By the way, this stove will absolutely not work without VERY WELL seasoned wood.. It just will not perform without VERY DRY WOOD.. If you try to burn less than dry wood in it, you will be cussing the stove for being no good.. This is my experience with this brand, hope it helps. Looked for my manual, cant put my hands on it.
