Ok....  Picked up a new Hearthstone Mansfield yesterday.  I have a SuperVent through wall chimney setup.  I bought DuraVent DVL double wall stove pipe with the stove.  I bought the DVL stove top collar, one pice of telescoping DVL stove pipe, and one 90 degree elbow of DVL.  Now.....  How do I connect that DVL to the wall thimble.  The adapter (on the wall) that plugs into the first section of chimney is made to connect to single wall stove pipe.  If I try to connect the DVL to it, it just slides into the DVL section as far as I want and does not seal.  Any suggestions??
Thanks
Chris
