We are new owners of the Harman Accentra freestanding model with the OAK. Have only had it for 7 days & never owned a pellet stove before. I have read the manual, watched the dvd, looked at the Harman sticky on the forum but I have a few questions. I have the stove in room temp Low mode, Feed rate 3, room temp 70 & we tried Hamer pellets but are currently using Lignetics. I am sure I need to better fine tune my settings. We are getting ready to clean the stove on Wednesday. There is a lot of build up on the compass design.. is that normal? And can you have a flame that is too high? I sent a pic to someone & they thought the flame was high... they don't own a Harman though. I get a lot of ebbs & flows with the flame being low then being high. Any & all input is greatly appreciated.
