Smokin'......not

The upstairs fireplace has been equipped with a fan on top of the chimney to help keep it from smoking. It seems to be working and we can have a smoke free fire upstairs. But, the house is soooo tight it even sucks smoke in around the edges of our closed spring loaded damper on the downstairs fireplace. So...the downstairs fill with smoke. Back to the drawing board. Next try...somehow rigging a box to place the fan on top of both flues. Stay tuned. Clyde the cat seems to be oblivious to any issues what so ever. Guess he doesn't hear those coyotes howling outside.
