We have a Defiant Encore, new to us, which fired great the first time we used it. The second time was during a high wind and it overheated with both the damper (located in the stove) and the air intact closed. We assume it was the effect of the wind--are we right? High winds are frequent in our location--what can do so that we can run the stove, wind or no wind? (Would a flu damper help?) Many thanks!

CAT or Non-Cat stove? How tall is the chimney?
Yes, wind blowing through the cap at just the right spot will create an increase in draft. It is possible an in-line flue damper would help to slow it down some.

Yeah high winds will affect us but never to the point of over heating. We lock it down by chocking down the primary air on our QF 4300st which is most of the time opened all the way for the hottest burn.
The stove is a CAT' chimney is about 4 feet and has a cap. Anything else you can think of to offset the effects of wind? Many thanks.
High wind moving across the top of a flue decreases the pressure in the flue, increasing draft. You can purchase wind hats, some of which rotate, to reduce this problem. I experience it fairly frequently during the winter, and sometimes prevent overfiring by not loading the stove with a full charge of wood. The problem is, then your burn time goes down. It's part and parcel of dealing with wind. Part of the problem is that on most modern EPA stoves, while you can reduce primary air coming into the stove, you have no control over secondary air... so long as there is draft, air will come out your top tubes.

You mean a damper in the flue? I wouldn't suggest it. Do you have any photos of your setup that you can post? A little more detail would help us out a bit.
Also, when you are looking at hats, don't get the ones that increase draft as the wind blows... that certainly won't help your cause! :bug:

I typically do not advocate flue dampers either, but in your specific case I would consider one. Make sure the damper is not located too high in the pipe so that it gets a real good "heating" when you fire your stove. This will reduce the chances of any buildup on the damper.
I think YOU may find a damper to be the right tool to slow down the draft. The wind caps are also a good idea, but be aware that it may have more of a cooling effect for the exhaust than a normal cap, meaning it could have a greater chance of buildup.

! Or was that meant to read 14 feet?- Status
