My quadrafire 1000 is putting out extremely large flames the fuel adjustment all the way down and am using standard pellets from local mill. I tried adjusting the plate on the fan on the lower left of my unit but the flames are still way too big for the recommended amount. I am still using my clay firepot but I see some hairlines cracks forming after a thorough cleaning today but it is not about to fall apart. My altitude is at nearly 10000' I don't know if this has something to do with it. I've never had the stove flame to the perfect 2"-4" height above firepot recommended by Quadrafire but lately it seems to really be burning like a wildfire! I was thinking about modifying my fuel adjustment plate to a smaller size by welding a small extension but I thought I'd see if you folks have any other recommendations (I have tried all suggestions from quadrafire manual)? Could it be a leaky door gasket allowing too much air in?
 
What does your venting consist of. You are likely pushing a lot of limits at 10,000 feet.

Large loopy flames are usually a sign of not enough air through the burn pot.

If you have bad door gaskets you need to replace them as they will allow air into the firebox but it won't go through the burn pot.
 
I have a 4" off the back of the pellet stove and elbows to a 8" pipe to 30' to daylight. I have had this setup working excellent at one time just something has changed.

Edit: Everything as of current is clean as a whistle less than 24 hours since cleaning
 
There was a person on here last winter that was having massive burn pot backup.

After tearing the whole stove apart it turned out to be a broken bolt holding the burn pot on its gasket.

Like with a door gasket air was being pulled through the stove by the combustion blower but it wasn't all going through the burn pot.
 
I am going to evaluate all my gaskets right now I don't have any bolts on my ceramic fire pot could it be the cracks in it? I think I've never replaced the door gasket while it seems in excellent condition I know that is a cheap fix so probably worth trying.

What holds the pot in place?

Smokey the ceramic pots were heavy. The weight of them was enough to seal them to the gasket.

OP are you sure the pot doesn't have a crack in it? also the gasket may have warn spots were it might no seal right. AFAIK the gasket is not available anymore. They replaced the pot with a cast iron unit and the gasket is different.
