Recently bought a 1960 house - the living room has a modern vented gas fire.
In the wall near the fire is a vent that goes straight outside and let's in a howl of cold air. It's above the floor level (solid concrete floor anyway) I've also noted two more in the kitchen inside an airing cupboard - again well above floor level.
Are these left overs from the days of open fires / designed to let out natural gas and smoke? Or are they ventilating the cavity wall and the inside of the house?
Can I block them up and remove them as they let out quite a lot of heat at the moment!
