This fire occurred in Weatogue, and is an example of a backdraft fire – these can be extremely dangerous if they are not handled by a firefighter or someone with ample training. A lot of times, these fires occur when a room is combusting and has minimal oxygen exposure, however when someone opens a door/window or opening to the room, the oxygen then begins to combust causing the gas to ignite. As heat rises, the heat and fire immediately progress to the where there is no exposure but there is a source for ignition, hence why it spread down the hallways so rapidly.
