I bought a new home with an existing Whit field free standing advantage as a rookie pellet stove operator I wonder If I'm doing something wrong. I can only go about 48hrs before the stove is so full of ash its quite frankly ridiculous. I bought a ton of Premier Pellets (appalachian hardwood fuel) from Lowes are these pellets garbage, waiting for a Harman Accentue to be installed in my basement, the local stove shop reccomends Eneregex Canadian Pellets. Lookin for any advice ?? Thanx PS I have twice in the last 3 months completely dismantled this stove and cleaned everything spotless flu pipe too.
