Hooking up a stove in our mobile home. Plan to use DVL stove pipe to wall thimble and out to Dura Plus chimney. Telescoping DVL from stove (top outlet) to 90, then maybe small length of pipe to wall thimble. My first question is do I need some kind of adapter to connect the DVL to the thimble? I’m hoping I can just hook the 90 to the thimble if it gives enough clearance.
