    Finally broke down and purchased the Harman Insert. Connecting it to an existing 4" flex liner. From the dealer
    and researching this forum, I have noted most insert the flex INTO the stove stub, silicone and secure with screws. I personally feel the flex should go over the sub eliminating any potential leak.
    The manual states The unit comes standard with a 4” pipe stub. • Part #1-00-574034 is for use with 4” PL vent starter pipe and 4” stainless steel flex pipe (Part #1-00-574034).

    Is there any specific adapter to couple the stub to flex or even if I had to place a rigid pipe adapter on the stub
    and add a short pipe to flex adapter?

    If I recall, there is a seat/flange/lip on the insert frame exhaust stub that makes the id smaller than 4". I too was questioning this, but once I saw the actual shape and size of the arrangement, I was satisfied. FWIW, I had one power outage with the pellet stove running and had zero issues with leakage/smoke. I wouldn't sweat it. Good luck, mine has been great!

    Thanks - 1 reply out of 50+ views! I,m sure securing the flex into the pipe stub and silicone sealing will be fine.
    Just surprised can not find on line a stub to flex adapter that fits the 52i. There was one for the older stove when it had a 3" vent.
    Be interested to see if anyone connects Duravent PVP pipe to the unit and what parts were used.
