You may be right/proper about the P series being more forgiving.But,if it is an older accentra,that should have had the gummy stove upgrade,or,does not have the latest control board(which really makes most Harmans run cleaner,yet,more heat goes out the stack),Why bring in the swimming pool crap on a heat forum. Your comparison is poor.An Accentra,on soft pellets,I s supposed to run for a ton,before cleaning,with 1-2 days of cleaning/scraping the pot.On hardwood pellets,will be more.But,due to the design of the stove,1/3 of the ash misses the ash pot,after 1/3 of a ton,the ash buildup misses the ash pot(open the door,the ash is build up on the lower hinge,drops off when opening the door),The Accentra,being cast steel,retains the heat better,Untill the last Harman Control Board upgrade,as,the board upgrade keeps the exhaust blower running much longer,than the previous control boards.Therefore,the shut down pellet stove draws more heat out of the house,reducing efficiency..Hope this helps.Clean an Accentra,whenever the ash comes out on the lower hinge,even though the ash pot is not full.
