    I am waiting for my Osburn 2200 insert to arrive and want to install a blocking plate and my flex liner while I'm waitng for it. What type of material should I use for the blocking plate? Is there a type of pour insulation that can be used to insulate between the liner and the existing flue and is this even something that is worth doing?

    It may be best to wait for your stove because liner placement will depend on where the flue collar lines up from the stove. And thus the blockoff plate is the final piece to the puzzle.

    Galvanized 24 gauge is what is best - in terms of workability, etc.

    You can make the plate, just don't cut the whole yet. Did you see the instructions for making a plate in our info section?

    I second that motion. I put it in before the stove arrived based on the manufacturer's specs and had to rip it out and do it again.

    As to material, the six buck piece of galvanized sheet metal in the plumbing section at Lowe's will do it just fine. Look over in the duct work section. The employees won't have a clue.

    Remember, a set of good vise grips or channel locks will help when you are trial fitting, otherwise you will never get it back down after you push it up there.
