Hey,
So i had my stove going yesterday and i had the damper all the way closed. the fire seemed to be getting too much air making the stove go over 700. Door gasket looks ok. so do i need to open the stove and block off air holes ?
Thanks all
 
700 hundred is fine. If you start getting past 800, that’s a little different. Not unusual for low air settings on epa stoves.
 
When I added my damper it made all the difference in the world. Much more controllable and extended burns. What is your flue type and do you have a probe thermometer? My sweet spot is flue between 700-750 and stt 550-600 blower running on high.
 
Many here have blocked off the unregulated boost air holes in their stoves. This usually helps with a little more control.

Thanks for the replies.
Would the air channel you're talking about be the one in the manual that says "rear air channel operates independently from timer" ?
There is a diagram on page 11 . https://downloads.hearthnhome.com/installmanuals/3100_MILLENNIUM_C_FS_WOOD_OWNERS_7033_351.PDF
I’m not really familiar with Quad stoves. Usually there is some unregulated air that is located in the front lower firebox called the doghouse. It’s more or less a boost air to get the fire going quickly. Quad has the ACC system so maybe that’s connected to this boost air? I probably wouldn’t mess with anything til you get familiar with your new stove.
 
For clarification, when you (OP) say damper you mean the stoves primary air control, right? When the others say add a damper, they are talking about a stove pipe damper like this:
[Hearth.com] Are EPA Holes a thing ?

You would need one that matches the stove pipe you have attached to your stove. I have Selkirk DSP, so the pictured damper is what I have.

I had to add one. My draft was too high.
This is a thread where I show how I measures my draft. You don't have to go through all thus. If your stove is in good working order, the door gasket is good, that kind of thing, but it wants to run away on you... a pipe (or key) damper can help.

 
Yes, i do mean the primary air control.
not sure how long the flue is, i can check later.
