I have a 6" SS insulated liner installed within my exterior block chimney--the terra cotta tiles were removed to accommodatethe liner. Because of this, if you open up the clean out door of the block chimney and grab the bottom of the liner, you can move it back and forth an inch or two within the block chimney. You can also grab the liner inside the wall pass through and move it in and out an inch. The pass thru itself stays in place. I never thought it was a big deal--I have always been careful when cleaning the pass thru--not to push it too hard with the brush.
I have a top vent oslo, with about 40" of vertical black single wall, leading to a 90 elbow which connects directly to the pass thru and on out to the exterior. Last night the wind was howling and I noticed the liner within the pass thru was moving slightly--causing my vertical black pipe to move back and forth about 1/2 inch. Is this normal? I contacted the chimney service who did the original install and they said it was. Anyone else have "play" in their liner?
Thanks
