Old Harman Accentra fire pot upgrade?

[tbear853]

Mine now has the full row on the back or 5th row of holes. It had the short row, but I added four holes to complete the short row. Just bought it 2020. I then added a flame guide over the rear, about 2" wide steel plate. It works because most of the stove is an Accentra in disguise. I recall thinking the partial back row had something to do with placement of an ignitor which my stove does not use. I alse filled two mount holes for the ignitor.
