Dave, cooker is a flueless appliance. The regulation requires an openable window or some such form of vantillation otherwise there is a risk you could pass out due to depleted oxygen levels.
Oxygen in the kitchen supports combustion, which is converted to carbon dioxide during combution process, oxygen level thus dropping and carbon dioxide level rising. You are cooking in the internal kitchen with no means of ventillation, soon you will start to feel woozy.
