I have a particular brand name in mind, but not really wanting to tag this thread with it until after this first question...

How difficult is it to install a liner in a chimney? I have been in HVAC service for 11 years, humping ladders and doing gymnastics and contortionist maneuvers in general the whole time.
The locals here who are prepared to sell me an insert are telling me 8 to 15 for the installation, and I don't mean hours...
What kind of termination is standard at the chimney cap?
If it is necessary to defer to the pros for the sake of the public bulletin board, then e-mail me privately with such considerations as requested.
