I have a older Whitfield advantage II pellet stove Model#95051..I have the same chimney set up as in the picture.and my control board is the same as picture 2 and has the same settings ..I am finding the tee with clean out that is outside is full of ash every few days and needs to be cleaned out.Then when I use the chimney sweep every 2 week there is a lot of ash that comes out of the rest of the pipe,is this because my stove in a top feed unit ? I know that when the pellets come down the shoot and fall in the burn pot there is hot ash that fly's in to the air and gets sucked out the pipe Maybe I have the exhaust setting up to high ? I find if I turn it down the glass gets black and the pellets dont burn fast enough so it gets backed up .Is it normal to have lots of ash coming out the chimney ? Its my first year owning a pellet stove so I dont know how they act or if I need to chang the setting differnt ,,Thanks for any info
