I renovated a bathroom and the existing 2" x 10" HVAC register had to be moved to a different location. Previously it was just linoleum over the plywood subfloor and now it is tile on the ditra on the subfloor. The old hole in the subfloor was patched and a new one cut. However the duct boot was nailed to the subfloor in the old location using what appears to be 1-1/4 roofing nails. I have a few questions concerning installing to the new location.
How do I get nails in such a small opening (see attached picture)? Do I only nail on the short side which gives me much more room for a hammer? The old installation had nails on the long side but I am not sure how to do that.
The old installation wasn't sealed in any way, should I seal between the duct boot and subfloor using mastic tape, silicon, or something else?
Should the top of the duct boot be flush with the top of the subfloor (as shown in the picture), or should I bring it up to be flush with the tile? The tile doesn't come all the way out to the edge of the subfloor hole.
Thanks for any help.
