The flare stack tower puzzle in Silent Hill: Townfall begins with a blaring alarm echoing through a gloomy four-level ruin, forcing players into one of the game’s most intricate environmental challenges. During the mission titled “Fix This,” Simon must navigate a multi-step process that involves locating a controller key, entering two distinct security codes, and rotating valves across every floor to reconnect a red pipe system before he can escape through the pipes.
This guide explains exactly where to find the controller key and how to rotate each valve in Silent Hill: Townfall. The puzzle is not simply about silencing an alarm; it requires players to piece together information from a “clamp release” file while coordinating actions across four separate floor levels, making careful note-taking essential for success.
Finding the Controller Key
The “Fix This” mission opens at the CEG HQ, where Simon becomes trapped in a multi-level area dominated by the flare stack tower at its center. Players should first collect the “clamp release” file from the table positioned opposite the elevator. From there, take the elevator to the second floor, where a controller key sits inside a small box next to valve two.
This controller key serves as the gateway to manipulating the valves below, but it alone cannot silence the alarm or move any handwheels. Players must also gather the correct codes from the clamp release file before they can make meaningful progress on either front.
Turning Off the Alarm and Releasing the Clamps
Return to the ground floor and apply the controller key to valve one. To turn off the alarm, players must identify the correct code listed on the clamp release file obtained earlier. The alarm identifier displayed on screen reads 77289, which corresponds to the code A5D7.
The alarm identifier is 77289, meaning the corresponding code is A5D7. Insert that code on the machine and press OK before moving on to release the clamps with a second code from the file.

However, players will quickly discover they still cannot turn the handwheels even after entering this first code. Interacting with the flare stack’s command console located on the right side of the wheel at valve one requires a second code found at the top of the clamp release file: E3E3.
Once both codes have been entered successfully, the clamps are released and players gain full control over the valves across all four floor levels.
Solving the Valve Puzzle
The goal now is to reconnect a red pipe that circles the flare stack tower. With the clamps released, players can use the handwheels to rotate the tower on each of the four floors until the red pipe connects fully from top to bottom.
On the ground floor, turn valve one twice to the right until an S-shaped piece of red pipe appears before you. On the second floor, turn valve two once to the left so that no red pipe sits directly in front of you. The third floor requires turning valve three twice to the right, producing a horizontal piece of pipe in the middle and another in the top left.
To fix valve four, rotate it twice more to the right. Players should then see an L-shaped pipe on the flare stack tower, indicating that all valves are correctly aligned for the final step.
Completing the Mission
Return to the ground floor and interact with the flare stack command console once more. This time, press the “gas flow,” “flow test,” and “ignite” buttons in sequence, which completes the flare stack puzzle in Silent Hill: Townfall.
To leave the area and finish the “Fix This” mission, players must crawl through the pipes that appear in the far left corner following an explosion. Mastering this puzzle rewards players with continued progress through Simon’s harrowing journey, demonstrating how Silent Hill: Townfall blends atmospheric tension with layered environmental problem-solving.
