I just went through my first ton of hardwood pellets with my new 2022 Accentra 52i-TC insert. I have had a wood stove for 10-years and love the pellet stove life. I am now looking to preform the first full cleaning which involves sliding the stove out, but I can't find any details on the size of the brushes or length needed for cleaning the interior vent tubes and the flue duct for this stove.
