So, the current vent on our Boler
is smashed, and was taped up by the PO to prevent leaking.
Chris and I bought a new 14" vent, took the old one off and just placed the new one in to see what was what.
A couple questions arose from this:
1. The old vent was sealed with black putty stuff. Does ALL this need to be removed? Or will the new butyl putty tape smoosh in and around this and be fine? We've removed what we can with a utility knife already.
2. The screw holes on the new vent don't line up with the old vent. Will it be held on just fine with just butyl putty, or should we drill new holes? If we have to drill new holes, is that a big deal? Or just drill them and be done with it?
3. It seems that the vent company was anticipating a thicker ceiling on which to mount this vent; when the vent is pushed all the way down the interior trim can't sit flush with the ceiling on the inside. Should we mount this vent with the interior trim flush with the ceiling and then rig up some sort of mounting collar on the exterior? Any suggestions for materials if that's what everyone would recommend? Or is there a pre-existing product for just this situation?
Many thanks for any advice!!
