Just replace the rules sections from the original mission description with these if you're playing Space Hulk straight out of the box.
Mission I - Breakthrough
Deployment and Forces
Space Marines:
The space marine player has two squads, Both Blood Angels Squads. The first squad consists of a sergeant armed with a Thunder Hammer and Storm Shield, a marine with an Assault Cannon and three armed with Storm Bolters and Power Fists. The Blood Angels squad consists of a sergeant armed with a Power Sword and Storm Bolter, a marine armed with a power fist and heavy flamer, 2 armed with Storm Bolters and Power Fists and one armed with a Storm Bolter and Chain Fist.
Special Rules:
Malfunctioning Doors: All doors in this area of the hulk are prone to malfunction. Upon attempting to open any door, either player must roll a D6. On a 4+ the door will open as normal. On a roll of 3 or less, the door jams and must be destroyed in order for the player to continue. The marine player may do this in the normal manner while a genestealer player must expend one action point to destroy a door once it has malfunctioned.
Heavy Flamer: By firing off three flame counters at once, the marine player can create a persistent fire effect that will cover one counter for the rest of the game.
Remove rules for Power Axe and Cyclone Missile Launcher

*Mark your Beta Strain Genestealers out from your normal stealers with some kind of counter so you can keep track. Placing a purple arrow under their base might be an idea.
