Where to fit vent in kitchen

Hello people

Hope your all well and safe

My gas oven was releasing too much Carbon monoxide so had to be turned off found out was faulty got a replacement . The gas engineer said I need to get better ventilation in my kitchen and suggest I remove the kitchen door as a temporary measure

At the moment the kitchen leads on to a conservatory. I have no hood pipe going out as next to the kitchen conservatory wall is the down pipe.

Any ideas have I can improve ventilation ???
