So, I have about 25 bags of pellets through my month old EcoAire 2400 window pellet stove. Its running great, and with softwood pellets it will go about 2 days without cleaning, even with most of that time set on 3 or or above. I have only two complaints: 1. Starting straight out of the box, the pressure light flashes during operation intermittently, though the stove keeps running. I called U.S. Stove, and explained that I wanted to know what the flashes meant, and got promised a followup call or email...I'm still waiting. Does anyone have a direct line or extension to get a real engineer on the phone there? 2. The vent holes at the top of the box (i.e. where the exhaust gases go) have slowly distorted and even lost some metal. At first, it just warped the vent area, then it actually ripped the metal. See the attached pics. Since it runs OK, I suppose the only issue is that it probably is getting more draft than it should. My inclination is to wait until the heating season is over, then make them replace it, since loosing some pellet efficiency beats the heck out of burning HHO. Any risks to that? The holes seems to have stabilized now. (Sorry for the cell phone pics, the wierd red stuff seemed to be sort of a paint or primer on the firebox that's showing (my vaccume nozzle gets red stuff on it when I vacuum that area).
