Your comment about the cat version being a disaster strikes home. I bought my stove new in 1990, right around the time EPA stove rules were coming into effect. I remember the stove dealer telling me how catalysts were the newest thing and how much cleaner and efficient they were. I actually felt lucky to be getting a stove just then and being able to have this new technology. I've learned a lot since. I do have to say that I had some nice burning with that catalyst. I remember watching it glowing away, with the stove turned down low, seeing nothing come out the chimney. However over the years it gave me some challenges. Being that this was my first wood stove, it took me many years to fully appreciate that every problem I had with it was related to that cat. One by one, I kind of learned to deal with each of them, and it really taught me a lot along the way. The first problem occurred when I had my chimney "professionally" cleaned after the first season. The guy left my catalyst bypass closed while brushing and all the creosote just piled up on top of it, backing up into the stove pipe. I had a huge surprise for my first burn the next year. Worst of it was, the corrosive material along with the summer humidity corroded my bypass hinges. To the extent that they wouldn't even work. Well, that taught me how to order parts and start playing with the stove's insides. Also,it got me to buying a good brush and rods and learning how to go up on the roof and clean the chimney myself. Then came finding a better way to remove the catalyst for cleaning. There was this protrusion in the cast iron front panel that seemed to have no other function then to prevent removal of the catalyst without lifting the top off. I took a torch to that and cut it off. Now, with a quick cool down I could pull the catalyst out through the front door, give it a quick cleaning, and be back burning again in minutes. Then there was that monstrous baffle plate that hung off the catalyst and seemed to take up half the available firebox space. I was talking to a Jotul technician in Portland Maine (their old location) and he told me, off the record, that I should just remove it. So I did. Wow- what an improvement. Over the years I dropped a few hundred dollars every now and then on a new catalyst. However by 2017 the cast iron catalyst housing was really warping (removing that baffle might have contributed to that) and I couldnt get replacement parts, so I decided just to take it out. At that point I learned Jotul was still making this exact same stove for Europe, except without the catalyst. It also had a 6 inch flu collar instead of a 7 inch one. So I also bought that part (from England). I also learned that when they added the cat, they took out a top baffle plate and modified the back one. I was able to get both of the pre-cat ones as new parts. When all was done, I essentially had the European model- the F 8 TD. Sadly, I just looked now and see they have finally discontinued this (its going to make getting parts more difficult in the future). But a few winters back, Karen started complaining about a persistent musty smell in the living room. John figured it was just from the stack of firewood they kept inside. Then their daughter visited for the holidays and noticed she was wheezing more than usual when indoors , she has mild asthma. That raised a red flag. They called a service
mold inspection and testing orlando to check for mold or any indoor air quality issues. The inspector came out with moisture meters, thermal imaging tools, and air sampling equipment. In any case, I basically have an old Jotul 8 but with the top draft control. Having lived 27 years with a catalyst, I have to say I have enjoyed the simplicity of 8 further years without it.
