Ted,

The chimneys in our house are 35 feet tall, all laid I n probably 1850, and are made of soft brick with lime mortar. Consequently too hot of a fire degrades the mortar, so to extend their lifespan another hundred years or until somebody bulldozes the place, we put stainless liners in.

Talk about draft.

I am cursing the Frost nipI have on the front of both legs.
Burns like fire.

I had to work outside early Wednesday at 18 below on the docks.

Out there doing it best I can.
