That's a very good thought, but its not needed here... Ideally if I was concerned I would have a metal bracket above the durarock that is tied to the inside brick of the fireplace that would secure the black pipe prior to installing the durarock. But once this pipe is secured to the flu collar on the 404 it is more solid and stiff than anything (it almost becomes "one with the stove"), the 404 has a removable baffle so when cleaning I never have to remove the stove or disconnect the pipe to clean it as I wish.
So currently I have this pipe assembly put together and it can slide up and down within my durarock (its sitting on a 5 gallon bucket at the height of the stove flu awaiting my son to help me), it has some play forward and back, left and right, up and down to make install of the stove easy peazy!... but make no mistake, once I tie it to the stove it wont budge unless I unscrew it from the flu collar of the stove (and I have a 7' strait run up to make sure it gets into the terra cotta flu above the "shelf area" but in reality I could have just done a 3' run up and it would work fine). I will also inject a bead of cement around the pipe at the durarock after the stove is installed (its such a tight fit I don't really need to but I will anyways because I wont have to replace it, EVER...if you know what I mean
!). You can make this fit so tight it will actually hold the pipe from sliding up/down to some degree.
If you have a similar set up and a square or round 8" terra cotta flu above, I've in the past used a decorative flange and tacked it to the top section which you can then force up into the terra cotta (these decorative flanges are so thin and flipsy it will bend as needed when your forcing it up and this helps keep the pipe hanging as well as keeping it centered inside the terra cotta).... I was to cheap to spend the $10.00 on one but if I had one I would have done this as well
