Im thinking of purchasing a Breckwell P23I and wanted to do install myself. I was wondering whats the difference between 5 ft and 10 ft tube/pipe and how in the world do you tighten and seal the pipes and everything and slide up into the flue? Do you have to tilt the unit or something? Sems like you would need more than 2 people to get up in there to do that? If anyone has done a complete install of an insert , I would appreciate any help here.

PS When you bought your insert, did it come complete or did you have purchase the trims, hinges, the door separately.

Thank you again!
