LOOKING FOR HELP... I have a whitfield profile 30 free standing unit.....this is my second winter with this stove.... last year I burned 3 different types of premium soft wood with little or no problem other than alot of ash and clinkers( clean once a day)... this year I thought I would be smart and buy northern hardwood pellets by cubex co. Now for some reason my stove is contiually shutting down( burning out) the ultra gate is empty and clean.... no clinkers..... any idea's? is it the pellets or is it running too hot? I have tried every possible configuration with auger speed and blowwer speed along with damper settings.... last night my wife said it burnt all night with no problems using a bag of soft woods.... overheat or pellets themselves... can I adjust anything in order to make this stove burn the 300 bags of hardwood pellets I own?
