I have an existing wood stove that the flue pipe (8") goes straight back from the stove into a brick wall then up into the chimney. The chimney flue is stainless and is 8" all the way up. The woodstove is in the basement and the dedicated chimney is 3 full stories above it. I have always had a very good draw from this setup. I would like to upgrade my woodstove to a new Jotul. Unfortunately, the flue pipe is only about 18" above the base of the woodstove and most woodstoves with a rear flue are several inches above that. I understand that its desirable (or is it in the code?) that the flue pipe from the woodstove to the chimney should slope upward. Is this mandatory. Since I have such a good draw, and I'll have to use an adapter (8" to
6") anyway which will help the draw to the woodstove. Under these circumstances, can I use a modern woodstove that has a higher exhaust flue than the input to the chimney? I'm probably not using the correct terminology I realize, so let me explain it this way. The current flue pipe is parallel to the floor. If I install a new stove, the pipe will slope downward from the woodstove to the chimney pipe for about 24 inches. Will this be ok?Thanks,
Peter
