Length of Chimney Liner

[camdids]

I am going to have my Chimney Relined with SS Liner for my Harman Accentra Insert. (Because the Dealer recommended 5ft of flex direct doesnt work on big chimneys.) I see Harman specifies a Maximum 30 Lineal FT vertical. From where my stove is situated, I am looking at around 26-27ft, maybe 28 with the cap.
Has anyone pushed this to the limit without any issues.

I would use a 4" diameter.

Never considered any other size. Just wondering with being so close to Harmans maximum legth, if anyone had had any issues with that length.
