Atomic Heart is filled with many puzzles for players to solve as they explore Facility 3826. Players step into the combat boots of a hardened Soviet soldier codenamed P-3. His glove comes equipped with many useful abilities as he travels through the destroyed laboratories in the facility. The early levels of Atomic Heart take place in the underground Vavilov Complex. To escape the complex players need to acquire four separate canisters and plug them into the Birchtree. One of these Canisters is obtained through the "Into the Fire" quest. Follow this guide to solve the Boiler Room puzzle and get the Heat-Resisant Canister located in the Hot Workshop.
