Hope someone can help? I just purchased a new Heatilator PS50 pellet stove and it does not seem to feed enough pellets. Does not even cover 1/4 of the bottom of the burn pot, so after it drops the initial pellets it does not get hot enough to drop more pellets to start. I have to hit reset two times to get more pellets to startup. Once it is started and the feedgate is full open on high you can barely see any pellets in burn pot. You can see most of the holes in the bottom of the burn pot. Stove never seems to get very hot, even on high. You can touch the top of the stove and leave your hand there for a while. My friend bought same stove, at the same time and at the same settings his burn pot is full of pellets, with good flame and you cannot touch the top of stove. His burns much hotter! My door is tight. When I plug stove in the blue light on the controlbox blinks 4 times. I have only burned about 3 or 4 bags since install. Venting is a "T" out of back, 4 foot up, 90, 1 foot horizontal to open air. 4" pipe and I am in Colorado. How do I get more pellets to drop? Any help is appreciated!
