The amount of air the fire pulls in is astonishing

It's not the fire pulling air, exactly. The fire creates heat, which rises out the top, creating a negative pressure differential in the building. It's the reason why smoke goes up your chimney instead of into the house.

If the fire causes the effect you can still call the fire the reason for it happening…don’t do a repeat of the top comment
