On my second season with our buck 91. Using it as a freestanding stove. It works great except when the blower is off, you get super high cat temps. I'm concerned what the stove would do if the power goes out. Any thoughts?
what temperatures are you seeing? What size chimney is it hooked to? How tall is it? Do you have a stack damper?[/QUOTE
It goes anywhere from 1700-2000 with the blower off. As soon as we turn the fan back on, instantly drops to a safe temp. It has an 8" flue connected to a 32 ft chimney on outside of house. We never had an issue of it not drafting. We don't have a stacked damper. Just really paranoid if we are at work and we lose power. With just a lil bit of wood in it, the temp is 800 with fan, 1600 without fan.
The air vents are off to the side of where the face of the cat thermo is, but the tip of the probe is inside anyway, and it does get hotter in that area when the blower is off. The breaker tripped a couple of times at my MIL's, and the cat temp went high once when this happened early in the load, when the cat was eatin'. You really need the blower to be running on this stove, but I've read here that others run their inserts with the blower off, so maybe some models are better able to shed heat without the blower on.Where is the cat temp gauge? If the fan is blowing over the gauge, you may be cooling the gauge and not the cat. My point being that the cat might be always that temp and you're getting false readings when the fan is on.

Wow, yeah, my cat temp sometimes pushes 1500 with the blower on, and the stack is only 21' and draws pretty strong. That's with an insulated liner in an interior chimney though...You are having problems with over drafting because of the height of your chimney. Put in a stack damper to slow it down.
Yeah mine did that inexplicably, as well. I already replaced the thermostat but it did it again. I have a new on/off/manual switch but I haven't put it in or run the stove yet this season. Other than those two items, I don't know what else it could be...blower? My stove is 7 yrs. old...I wouldn't think your blower would be worn at 2 yrs. (if you got the stove new.) I may email Buckstove and ask if they have any ideas. They have been helpful in the past.When we leave the house, we have the dampers set to where the cat runs at 1100-1200 because we are heating a 2800 sq. ft house. About a week ago, the fan shut off for some reason and the cat thermometer read 1900.
