Silent Hill Townfall: CEG HQ Flare Stack Pipe Puzzle Solution

Taking the elevator down at the start of Part 6: Simon drops you into a distorted CEG HQ with a single prompt: FIX THIS. The thing that needs fixing is the flare stack, a vertical gas pipe tower split into four misaligned sections. Nothing ignites until you kill the alarm, unlock the rotation clamps, line up every section, and run a clean flow test.

Quick answer: Grab the Controller Key upstairs, silence the alarm with A5D7, release the clamps with E3E3, then align valves floor by floor (right x2, left x1, left x2, right x2), run Flow Test, and press IGNITE.

Codes and key item for the flare stack puzzle

Two codes and one item gate the whole sequence. Neither keypad will accept input until the Controller Key is in your inventory, so collect it before you touch the lower control panels. The key also doubles as the Room 204 Key on your item screen.

Input	Where it goes	Result
Controller Key	Alarm Status panel slot	Unlocks the keypad
A5D7	Alarm Status keypad	Silences the alarm
E3E3	Command Console keypad	Releases the rotation clamps

The handwritten Reference Sheet on the table beside the console supplies alarm code A5D7. It shows the current alarm as 77289 and matches alarm 772-89 to entry A5-D7. On that sheet, beneath the “Clamp Release” heading, E3E3 is circled in red as the clamp code.

Get the Controller Key first

Skipping this step is the only real trap in the puzzle. Pick up the Reference Sheet, then power the lift and ride it up to reach the key before you start working the ground-floor panels.

Walk the dark industrial corridor to the lift control panel that overlooks the flare stack. This is the same panel you return to between every alignment, so remember where it sits.

Activate the lift and select the up control, bringing the platform to Floor 2.

On the second-floor walkway, open the small metal box beside the valve and take the Controller Key. Ride the lift back down to the ground control floor.

Silence the alarm and release the clamps

Both terminals sit on the ground floor. Handle the alarm first, since the valves stay locked until the clamps are freed.

Approach the left-hand console labelled ALARM STATUS and insert the Controller Key into the slot beneath the code display. This unlocks the keypad.

Enter A5D7 and press OK. The display reads “Alarm Silenced” and the status light turns green.

At the COMMAND CONSOLE on the right, enter E3E3 and choose OK. “Rotation Clamps Released” appears on the display, while the clamp indicator changes to green.

Engaged clamps prevent the valve wheels from moving the pipe sections. Before climbing, verify the green clamp message.

Align the four pipe sections

A red valve wheel appears on each floor, controlling the neighboring pipe segment. Repeat the same process at every level: rotate the wheel until its section matches the column, take the lift up one stop, and do it again. The turn counts listed below give the required alignment.

Floor	Valve turn
Floor 1	Right twice
Floor 2	Left once
Floor 3	Left twice
Floor 4	Right twice

On Floor 1, rotate the red valve wheel so the first pipe section lines up with the column overhead.

Return to the lift panel and use the up control to reach Floor 2, then turn that valve until the second segment connects cleanly.

Ride the lift up to Floor 3 and turn the third wheel until that section of the gas pipeline aligns.

Take the lift to Floor 4 and turn the final valve until the topmost section locks into place.

Bring up the lift panel, then choose GROUND to return to the ground control floor.

Run the flow test and ignite

At the Command Console, inspect the status column first. Outlet, Inlet, and each of the four Section indicators need to be green. An amber or dark light identifies a floor whose wheel needs more rotation; go back up with the lift and continue turning that valve.

Choose Gas Flow; the Inlet indicator becomes green.

Press Flow Test to verify pipe continuity. A correct alignment turns Sections 1 through 4 and the Outlet green and displays “Test Success”.

Select IGNITE. The stack flares red while radio chatter cuts over the monitor and a cutscene begins. This cinematic confirms completion of the puzzle and moves the scene forward.

Leaving the flare stack room

After the system comes online, cross to the room’s side opposite the console. Find the yellow light beside the rubble pile. Darkness makes the way ahead easy to miss, but a narrow opening sits left of the debris. Crouch through that gap to exit the area and continue Part 6.
