Can someone point me to where all the air inlets are for this thing? I've got to slow this thing down.

I've searched and read a lot here but not sure I have found a clear description.

I replaced door gasket today. Checked air wash gap, 3/16's on both sides but I still have a dirty glass on hinge side. Trying to figure that out as well.

I like this stove but I hate it about as much as I like it.

How tall is the flue system on the stove? Is there a key damper in the stovepipe?
 
That chimney height is under spec. If anything I would expect poor secondary performance from the stove. Describe the burning performance you are seeing and what is expected.
 
I lied, I just went and looked. Its about 20'. Burns great. Typical right to left.

I've got to figure how to slow down the secondary air intake.
 
OK, I had to go back a bit to refresh my memory. This is an older model. Did you get the baffle issue resolved? If yes, I'm wondering if the ACT is stuck open. Have you checked that?

Add a key damper to the stove pipe. That should make a decent difference. It's cheap and effective.

ACT?

The baffle, funny you mention that. I got a baffle board from Nevel Stoves in Jan. Its now in 4 pieces. They would NOT honor the warranty, saying I whacked it or something....which I surely did not. I have temporarily put a chunk of ceramic blanket up there. I think I will get a steel plate cut out. I wont go back to that type board and I surely wouldnt buy anything again from Nevel!

I found the secondary air inlets!
 
I think they use it in EnerZone stoves, among others. You might be able to buy ones that are made for a different stove, then just trim them..I didn't yet read the entire thread that I linked.
 
I'm not sure what is meant by the proprietary stuff. What year is the stove? Is this Quadrafire made by Alladin Steel or Hearth & Home?
 
Just in the manual it says "Advanced Combustible Technology (ACT)". That is the only reference.

This is about a 1992 I think. Hearth and Home
 
The ACT models have two air controls. The upper control is the primary air control, the lower one is the startup air control. The startup air control should be closed after 5-10 minutes unless the wood is damp. If you see the fire burning strongly at the lower rear of the stove with the startup air control closed all the way then it's possible there is air leaking in from there.
 
That is working properly. I replaced the door gasket yesterday, which is seemingly having an effect. I'll watch it today and see if it has improved things.

Good deal, a leaky door gasket can cause poor burning.
 
Well, it seals tight now and my glass is dirtier than ever. Whatever, thats a losing battle.

I also made a couple sheet metal flaps to close off the secondary burn air inlets under the stove. Fill me in on the repercussions of closing them once I put the stove to bed at night.

Closing off the air is going to make the stove burn dirtier. The problem is not too much secondary air.
 
When I fill the stove, go to bed, in about 2 hours, the thing catches up with itself and is raging. I dont want that. I want it to burn like an old school stove, slow and all night, according to the air input.

I can deal with dirty. I want to be able to smother it, if I so desire.

What moisture content is your wood at? This sounds like allot of the common problems people have with wet wood.
 
Well, in 45 years of burning wood, I've never checked moisture. Its dry.
How does a raging fire sound like its wet wood? :)
A raging fire 2 hours after starting it sounds like wet wood. Dirty glass sounds like wet wood. Baffles breaking that fast can be caused by thermal shock from steam. I don't know if it is the problem or not but there are some things making me think it may be.
 
For 2 hours the air is shut down, as much as it can be, In that time, it finally catches up with itself an ignites. I load the stove and shut it right down, prolonging it taking off into flames.

Really, it isnt wet wood. Its all pine that was standing dead and has been under cover for a while.

About the baffle, I've read of a lot of instances of that. From what I have read it sounds like heat is what seems to do it....not sure.
 
What temps are you running at? How long do you expect a 1.5 cu ft firebox to last especially with pine? Overnight probably won't happen
