1 Gather the following:
Do not use hydrogen as the carrier for conditioning! It could vent into the oven and present an

explosion hazard.
2 Place GC in maintenance mode: Maintenance > Instrument > Perform Maintenance >
Be careful! The oven, inlet, and/or detector may be hot enough to cause burns. If the oven,

inlet, or detector is hot, wear heat-resistant gloves to protect your hands.
Wear clean, lint-free gloves to prevent contamination of parts with dirt and skin oils.
