I mentioned this to env health officer in charge of job pointing gas fires and dangerous fumes to people asleep.
Bricked up fireplace no vent.
We installed a vent and when we lit a fire in the lounge smoke came out thro vent in the bedroom.
With regards to the above comment if you put an air bick in the stack externally with the fireplaces still bricked up you will have more condensation problems.
I m bricking up an unused fireplace in a house about 30 years old.
The chimbo needs vents in each room if you re open the stack or vent it externally.
I suggest putting a note in a plastic container within the fireplace pointing out that vent holes have been cut in the flue so they know to go look and rebrick them.
Lay the brick on the floor of the fireplace flush with the front of the fireplace.

The bricks should be flush against each other except for the thin layer of cement.
I did a grant job in kirklees it was in their standard spec to brick up bedroom fireplaces and insert a vent.
It had an open flame gas fire in it previously with a nasty brick fireplace.
As far as i know the fireplace was bricked up when it was originally removed and has never been used since.
Yes you will need an air brick or an air vent.
Press it down so the cement oozes out just a bit under the brick.
Apply cement in between each brick in the same way.
It s worth noting that although the chimney stack was originally outside there has subsequently been an extension built on the far side so the stack is now internal for most of the way up until about 2 3rd of the way up the second storey.
Wipe away the excess and repeat with another brick.
There s no problem blocking up plastering a redundant fire place but you should ensure the chimney top is closed off to water ingress plus it is best practice to vent the flue space so as to avoid condensation forming.
Normally when i ve seen internal vents in chimneys before they ve always been in the centre which is why i was going to remove a brick from the centre and stick the vent over that.
