Hi again.... my OPB will need to be scooped out... BUT the only time I did it (after running a few days) it was OFF and cold. I am thin king I will be afraid to clean it when I have to open the door if it is HOT or BURNING pellets.... is it right to just OPEN DOOR and scoop away while it is running? The booklet says HOW to clean it but says NOTHING about doing it while hot or ??? my model is a central boiler maxim 250 ... thanks!
