So I have been able to get a hold of ESW on two occasions and each time the tech has been very helpful. I was sent a new door gasket and ash pan gasket which was installed the other day. My stove was purchased in Oct 2012. The stove was made in August 2011. It was purchased new from Lowes. I am still having issues with black soot forming on my window. Here is my setup; 1) Stove adapter to 6" section 2) 6" section to 45* 3) 45* to 3' 4) Horizontal termination (adjustable nozzle duravent pro) I know I know, ESW wants >36" of vertical pipe in case of a power outage. My prior vent set up was as follows; 1) 1 & 2 from above 2) 45* to 1' 3) 1' to Clean out Tee 4) Clean out Tee to 4' vertical rise 5) 4' vertical rise to 90* 6) 90* to 2' horizontal 7) 2' horizontal to termination I know this set up sucks, but it was my only option until I had the opportunity to vent straight through my overhang. I did away with this and went to my current setup because when I pulled the plug to see if any draft would keep smoke out of the house it failed and I almost immediately began smelling fumes in the house. Therefore, there was no sense in keeping all those bends and increased EVL if it wasn't going to keep smoke out of my home. With that being said my stove is plugged into a UPS which I tested today and was able to keep the stove running for about 4 hours. It transferred to battery with no interruption to the stove. Now for my continued issue. Russ from ESW was the last tech I spoke with. Was great on the phone and went through numerous diagnostics. He said that sometimes the stove will reset to the default for the control board which is for a larger stove. My control board was at 2. Which is what it is supposed to be according to him. We reset my three lower buttons to 1-4-1. We then ran some other tests to check for air leaks. Hence the new gasket shipment. We then set my setting back to 1-9-1 which is what the first ESW tech had me set it too. So, settings 1 and two seem to be fine. Setting 3 is where my problems begin. The flame on setting three is uncontrollable. It hits the top plate and licks the windows. This then puts the soot on there. The flame becomes yellow and dirty. Russ said at setting three the flame height should be around the height of the downspout for the pellets. This is not the case for me. The auger seems to go about every 5-7 seconds as well. Any ideas? I'm burning Cubex pellets that I grabbed last weekend.
