Hello, I’m brand new to wood stoves, just bought a house that had very nice hearth so I decided why not. Bought a stove, now trying to figure out details of chimney install. Mostly I understand but I do have one confusion. Went to Coastal Farm & Ranch for help. They recommended to buy support box 6DT-CS11 and also chimney adapter 6DL-ADC. My understanding that I can go directly into support box with black pipe, please see two pictures. Help me understand, do I need an adapter between box and black pipe?
