These are the new instructions for how to use the gas jets. This procedure will supersede the "How to use gas jets" and "How to DPS with gas jets" pages.
Note: Approval to operate with hydrogen needs to be given. The authorization checklist is here: https://docs.google.com/document/d/13LvuOP7FBSUg4rawcie_g3sfOF0nirf4Z7H8PEaZ4EE/edit
