I have a new Quadrafire Santa Fe which works great. The only problem is that the burn pot door tends to stick. Hard to pull the rod to get it open and also tough to close it. There's no buildup in the firepot but I scraped it anyhow. I finally got out the WD40 and gave a couple of shots down the fire pot, also removed the ash pan and squirted some on the hinge. I had to reach back and help pull it closed so now it's free until the next time. I wonder if others have run into this.
