Hi All, I've been struggling with connecting DVL connector (part# 8674) to class A chimney, The double wall pipe side of the connector fits nicely into the double wall pipe. But it would only slide over a chimney section inner liner, not inside it how I thought it should work, engaging connector notches sticking outward. Then I read somewhere that DuraTech finishing collar is necessary for the connector to hook up to. I bought finishing collar, and yesterday tried to squeeze the connector into the finishing collar. It didn't fit, so I tried to crimp the connector, it would fit in but wouldn't sit there securely. I pretty much destroyed the connector with crimping, and have ordered a replacement. But I still have no clue how to properly get the connection between the connector and chimney finishing collar. Could someone help ? Thanks.
