I have a rear flue Mama Bear installed in my shop. I'm considering putting a baffle in it to increase heat and burn time. I have several questions and would appreciate any answers, pictures etc. 1. How high in the stove should the baffle be placed 2. should it be angled up or down, or kept parallel to the floor of the stove 3. how far should it extend towards the front of the stove 4. does it create a problem getting a good load in the stove 5. will a baffle be worth it to increase burn time and heat efficiency I would plan on using at least 3/8 steel plate, and I can weld. Thanks in advance, and if you like firewood related things you might enjoy my YouTube channel, YouTube.com/@oldguyfirewood.
Coaly posted some great info in my thread. I have a top-flue Grandpa (pretty sure it’s a Grandpa). It turned out that my chimney liner was compromised, plus were the liner attached to the stove. I had all that done plus a baffle. My stove works a million times better now. My baffle rests on firebricks that are resting on the ledges on the sides and back. It’s parallel to the floor, and it works amazingly well. It’s pretty close to the front doors…six inches at most. The draft is exceptional now. It’s a tiny bit harder to load the stove, but such a small price to pay. I don’t cram too much wood in at once—I’ve been told that you don’t want it burning TOO hot in these stoves. The baffle helps provide a secondary burn of smoke…there is considerably less smoke than before coming out the chimney. Burned up Fisher wood stove gasket
I have a Grandma. I welded some angle Iron on the sides and my baffle is 3/8" plate steel. I've been burning the same Fisher for 40 years.
Here is my baffle in Grandma after I painted and re bricked her. I cut some smoke holes in it, which helped with draft Immensely. If I had a southerly wind, I would get a "smoke roll" out the doors when I opened it if I was just lighting it. I did this to create a draft pull and it cured it! This is trial and error in my application because I'm right on the Coast, may not apply to you.
