I added two new 4" round ducts from the furnace before mine would not cycle against the high limit switch. One attached to each side of the heater box. I had lived with it 10 years before doing this upgrade. Heat is so much better now. My OEM floor ducting was collapsed giving about 70 percent restriction. I tried to prop it open but was not enough.
I wish I could see your pictures.
I think I see up to 3 ducts. Are those all added? All wall vents or is some through the floor?
