Fischer wood stove

[Black oak farm]

Good morning. We acquired our house about 1.5 years ago. It has 2 wood stoves with a shared central chimney. The one in the basement is unlined the one on the livingroom is. We had the one in the living room inspected and cleaned prior to use this year( 2 months prior to fire). We used seasoned madrone and oak that was kept in a dry shed . The day before Thanksgiving we had a serious flue fire. The fire wasent in the lined flue but in the space between it and the block chimney. When it was out and we inspected the fireplace there was about a 2+ inch build up of creosote in between the chimney and the flue. We pulled the flue and cleaned the actual block chimney. We had the flue inspected and wrapped and will be reinstalling this weekend. The new inspector believes the previous owner burned the basement stove and it leaked smoke into the living room stove chimney causing the build up of creosote. We dont use the basement stove so that shouldnt occur again. My main concern is the inspector said our fischer woodstove is prone to flue fires and recommends replacing it . I really like it because is has a cook top and we loose power frequently during winter. Are fischer wood stoves prone to flue fires? Any additional recommendations for our situation? I read a thread on baffles would that help? Advice on baffles when top vented? Thank you .

It is much more likely that the fireplace flue was not cleaned properly prior to installation of the liner. It is rather unlikely that the basement stove leaked enough creosote into the other flue to cause this.

I wouldn't say fishers are prone to flue fires more than any other older stove. But if not burnt properly they can create allot of creosote which can lead to a chimney fire. That being said a modern stove burnt incorrectly or with wet wood can do the same thing.

So basically there are many reasons modern stoves are better than old ones like yours. But I wouldn't say chimney fires are high on the list.

The inspector is sort of correct, though burning dry wood helps prevent issues as long as the fire doesn't smolder. The key issue is flue temperature. Adding a baffle will help a little by making the fire and smoke linger longer in the firebox but it will never be a clean burning stove. Does Oregon still have the trade in credit for old stoves? If it does, there are several new stoves that have a top you can cook on and burn cleanly. Another benefit is lower wood consumption and a nice fire view. Which Fisher model is this and how many sq ft is the stove heating?

I dont know the if oregon does a trade in credit. There is a taxe credit and we will keep it in mind for the future. I did do some research and finding a new insert that has a cook top seems to be hard. We do use a oil heater in addition to the woodstove. But wanted to use the woodstove to supplement and keep the cost of oil down. We have about 2400 square feet we are heating.

We originally thought the chimney hadn't been cleaned prior to liner insert but the way it was build up literally incasing the liner lead the inspector to look at the other stove. They share a chimney and the basement one is unlined. For some reasons the previous owners used the basement stove more then the livingroom one. But who really knows.

Do they share the same chimney or the same flue?

So theres one huge block chimney at the center of our house all the way to the basement. There is a free standing blaze king in the basement that uses one half the chimney. It doesnt have a liner. At the ground level there is a fischer stove that uses the other side of the block chimney that is lined. The inspector thinks the previous owner used the basement stove and there is leaks due to it being unlined. That caused the creosote build up in the Fischer's chimney.

Fisher Stoves

Bob Fisher is credited for conceiving and producing some of the first "airtight" welded steel plate stoves. He was raised in Oregon where he tried his hand at many jobs, including logging, farming and welding. It was his welding skills that finally set the stage for his invention. After buying...

So not even a clay liner for the basement stove?

I believe there may be a clay liner but I'm not 100% sure.

Take a look at the Drolet Austral or Legend III. It's affordable and a good heater.

I use an old stove in my home and dont have a creasote problem. I only burn seasoned wood and never crank it down to a smolder.. I run it up to temp and let it cruise.

Yes, if dry wood is burned and flue temps are kept above creosote condensation temperature in the flue then it shouldn't be an issue.
