Hi All: We are relative newbies with regard to pellet stove use. I checked the starter links prior to posting. We have purchased a used, Quadra-Fire Castile Pellet Stove from a relative. Original ownership of the stove involved professional installation, cleaning and maintenance for a few years, followed by secondary ownership, home installation and NO cleaning or maintenance for one year, followed by storage. We are the 3rd owners of this stove. We pulled the manual up online and cleaned the stove according to instruction. The problem we are having is that excess heat and hot embers are blowing out the exhaust pipe (out the wall installation - no vertical) and little heat - barely lukewarm - is coming out of the front of the unit. One issue we have noted is that the bottom window gasket is missing. While this is something we are getting replaced, it hardly seems like it will resolve the primary issue we are experiencing with this stove. I have not been able to find information specifically addressing this issue on Google or any of the forums. Help?
