I have a brand new vermont casting encore stove. Did the break-in procedure with three small fires, but then lit a larger fourth fire and the temp went up to 900+. Air control completely closed; made sure ash pan door was closed. Couldn't control it. The dealer came out and checked the stove and told me that I possibly had too much draft. I installed a damper in the pipe and tried again. Same result - I made small fire and added more wood. The damper and the air control were closed. Temp went up to 750+, could not control temp. The more wood I add the hotter and higher the temp. Has anyone had a similar situation?

That doesn't sound like fun. This is a new stove, we don't have a lot of data on it so far. Did the dealer actually take some draft measurements before making this call? If yes, do you remember what they were? Can you describe the flue setup including height?
Also, what size wood are you loading the stove with?

I'm assuming you are running this with the cat installed in the back of the stove, since it's new, or is the cat out of the back? Some folks with cat stoves have found opening the air a little can actually bring the temps down, as there is less smoke for the cat to handle. Did you try different lower air settings or just fully shut?

logger, it sounds like you have a good flue system, nothing really unusual here. There are many stoves that would purr along nicely with that setup. Did the dealer do a thorough check for air leaks? Did he at least do a dollar bill test on the gasket seals? If there is no resolution, does your dealer sell any other brands in case this one can't be tamed?

Sounds like you have an air leak of some sort. Maybe some of the stove cement cracked in transit. Maybe a bolt is loose. It does not take much much of a leak to let a stove run away. If the stove is a non-cat there will be holes open to the outside all of the time. I have a VC Defiant non-cat and you can shine a flashlight up through the air intake in the back of the stove and the light will shine into the firebox. the stove was designed to allow air into the secondaries that cannot be controlled with the air lever. Also, the EPA stoves are designed to operate with a 15' flue (measured from the floor up) on a 70 degree day. If your flue is longer and the temps are colder the stove will draw harder. It has nothing to do with the stove, its just physics. Our stove draws VERY hard on cold days. In some ways it self-compensates for cooler temperatures.
That being said, if you have a hard drafting flue your stove will be MUCH more sensitive to a leak. I have read on this forum that people have had huge problems with a stove running away and they fixed it by finding a tiny leak. Use a candle or stick of incense while the stove is running.
Good luck. I'm sure you can fix the problem.

Just a bit of info based on getting used to our new Encore 2n1 Model 2040 running in cat mode. First few fires after the break-in period seemed to be out of control as others have described. Temps getting over 800F and seemingly out of control. Seems it was a case of too much dry wood. As we have gotten used to it can now sustain temps in 450 to 650 with reasonable control. Would never load to the grille. This would most certainly lead to temps of 800+.
I just got a encore 2043. Love the look but having the same problem with it burning out of control. I found in the back, right back from where the air flap is, Another hole that i can feel is sucking air in. I plugged it up and now i can control it just fine. Only thing is that its hard to get a fire started, been just cracking the ash door until its going good. Thinking that because my vent stack is 8 inch, I just have to much draft maybe? Would it be better to put a damper in the vent stack rather then plugging the hole?
Thanks for any advice.
