Garage Firewall-Built-in Vac. Port

I have not seen a port to attach a hose penetrating the firewall. Does this port compromise the firewall?

If you are talking about a Central Vacuum Port in the garage wall to the house, it is not a problem unless it is a rated wall.
If it does not have a rating, then it is a non-rated wall and just a separation and the only requirement is (basically) to seal around penetrations so flame does not go through the surface of the wall around the penetration.
Hope that helps.

It’s a rated wall attached to living space.

How did you determine that it was a rated wall and what was the wall rated at.?
