We bought a farm that has 3 wood burners in the house. Two are Englander stoves, very straight forward, and one is a Cemi. The Cemi is in great shape, but I'm not sure what the two small levers at the to of it are for, also was wondering if there was a way to control the draft? Or is that what the two levers are for ? LOL. Just give me a simple stove cause I'm simple too LOL. Thanx in advance.
