Smoke Stack Intake
Starts the Smoke stack.
Vents surplus furnace exhaust to the sky.
The intake sits at the bottom of the stack's front face and is the only block of the build you pipe anything to: it pulls 96 L/s of gas off a run that faces back at it and throws it away up the flue. Place it facing the pipe that will arrive. Look at it to read what it cleared on the last tick.
