So I need to back up. After living here for several months, I look on the side of the wood stove. There's this knob bottom right. "Lo," "High." I turn it. Nothing. I take the bolts off to remove the vent to which the knob was attached. Wires go to the face of the interior and then lead to the back of stove. I can't make sense of the few mechanisms, so I enlist my boy. Funny kid. If something interests him, he'll redesign the Apollo capsule. If not, well, it's like talking to my dog - she'll look at me but won't give good advice.
Bye for now.
