Went in thru the front doors & took all the side,top,& back firebricks,plates,etc off Then went in there with my 2gallon shop vac. Man o' man, there was some serious ash behind everything . Also cleaned the outside flue AGAIN :shut: There was a ton of soot in there. Couldn't & wouldn't do the impeller exhaust blades cause of the gasket. Me thinks it's gonna be a long winter with those Athens pellets Muss
