Chimney hole after oil burner

[Ormriauga]

Hello!

In our utility entryway, there used to be an oil boiler. After changing the heating system, there is now a hole in the chimney that I wonder what I should do with. Is it just a matter of bricking it up or do I need to keep it for ventilation?

Hi,
Curious if you got any answer...? 🙂

Talked to the chimney sweep when he was by and he told me to seal it with masonry.

You can always "play it safe" and install a vent that can be opened, then you can easily get some natural ventilation in the room if needed in the future.
