This is our third year with the Dauntless. I can’t say that I love the stove, but I was doing decently well with it. As a ballpark estimate, we have had somewhere between 80 to 120 fires in it. We have had it professionally installed and, after each season, had the chimney professionally cleaned.

I think we are done with this stove, though, after what I went through tonight.

We started a fire around lunchtime. The temperature today was really cold. It was around 11 degrees when I went walking very briefly around 5:30.

About 6:45, I reloaded the stove with a mixture of maple and oak, all seasoned two years. The coal bed was thick. The flames started quickly under the wood that I had loaded (I usually put a two smaller pieces on the bottom because the doors get really smoked up if I don't).

After about ten minutes, I closed the bypass damper. I do not remember the stove top temperature, but I do remember that the probe was in the middle of the damper range.

The damper made a sound like a blowtorch, which it has done multiple times in the past. I had been planning to head into the basement to clean, but the sound continued, which was abnormal. I thought something might be wrong and decided to stay upstairs instead. When I noticed that the flames were dying on and off, I opened the bypass damper.

Flames were instantly everywhere inside the firebox. I’m used to a certain amount of flame, but this was more than normal. This concerned me, so I dialed the air back. Shortly after—and I don’t know the exact amount of time, but it seemed like only a few minutes—the inside of the double-wall stove pipe started to turn orange. Smoke came from the stove and activated our smoke detector.

At this point, I was really concerned that I was about to burn the house down, so I located our Chimfex, ignited it, and placed it into the firebox. Then I called the fire department, and we evacuated to a neighbor’s house.

Thankfully, by the time that the fire department arrived, the fire was somewhat more under control. One of the firemen mentioned that the cast-iron griddle on the top was glowing, which I did not see. They let it burn for about fifteen more minutes, but when it was apparent that it was not going to die completely on its own, they removed the coals and dumped them into a snowbank.

It’s entirely possible that this is somehow operator error. I don’t know if some combination of the low temperatures today or something else made this different than all of the other times we have had fires. All I know is that tonight something went very wrong.

I don’t love my local dealer as they have been dismissive a couple of times when I have had questions after the sale, and since I made the mistake of buying a VC, I can’t contact the manufacturer.

I understand some people on here are more skilled than I am at using this stove and using stoves in general. Like I said, this could be operator error. It’s just interesting to me that nobody else I know who has a stove seems to experience these sorts of problems.

Sorry for the rant. All that I can say is that the whole experience scared the **** out of me, and I won’t be using it again.
 
This is an over fire and they can be scary. I would get the stove inspected before using it again if you reach that point. There’s a couple things that stand out in your post but you might not be looking for that kind of feedback at the moment.

oak takes 3yrs to season, in many parts of the country. It may be in the Midwest, you are able to achieve faster drying times with above average winds?

If not seasoned below 20% moisture content, you most likely had creosol build up in the stove pipe and chimney. Probably a bit further up from the stove where flue temps are a little cooler. Being really cold out increases draft. I would think that the flames shot up the flue upon your opening of the bypass damper, igniting the creosol. This would also increase draft, burning everything available, ass fast as possible.

Thank you. Sincerely. I wasn’t last night, but I think I can deal with it today. What did I do wrong?

To be honest, I think, if I buy another stove, I just need something simpler.

The oak was a fraction of the maple—maybe 10 to 15 percent.

When I have measured in the past (I didn’t measure the load that I placed into the stove), my measurements were—if I recall correctly—around 12 to 14 percent on the maple and slightly higher on the oak, maybe 13 to 16. This is measured from the middle of a fresh split.

I’m not saying it wasn’t an issue with the wood, but I am very serious about splitting and seasoning in an adequate amount of time. The wood sits in my backyard where it is exposed to lots of wind and sunshine. I don’t tarp it until autumn, and I only tarp what I need for a season.

Couple notes:

I asked about creosote buildup when I had sweeps come after each of the past two years. Neither noticed any.

I went outside to see if I had flames coming from the chimney when I thought that I might be having a problem start. At no point was I able to see any. I don’t know if that makes a difference, but I have read that people often see flames when there is a chimney fire.

Should also be up to room temp and the prongs parallel with the grain. Just to be clear.

This is good. The wind is the major drying factor. When you do tarp, try just top covering your stacks, or pile. I realize many, who live in windy areas, can get away without stacking. Also elevate off the ground on pallets. Helps with complete air flow and separating from ground moisture.

Again, just for clarity.

One "vein" of wet wood in your stacks of only 2 or 3 stove loads of wood that's too wet and that is turned down much can mess up a chimney already.

On the other hand, maybe it was all dry and that is what caused an overfire; it taking off quicker than you could dampen it down, especially with it being colder than most times you've burned (I think), which increases draft.

I don't know the ins and outs of the operation of your stove, so I'll leave advice on that to others.
