Woodheater air supply

We have a built in 'Coonara' woodheater. You can always feel a draft which I believe is the air, coming through the room from windows or doors, that feeds the fire and ultimately goes up the chimney. I have heard that you can install a vent in the floor in front of the heater (we have stumps, bearers and joists) to let air go straight to the fire rather than through and doors/windows. Has anyone done this?
