Removing both the manifold and plumbing assemblies

Loosen the three captive Torx screws which secure the inlet to the oven,

and lift the PTV inlet out of the oven.

Disconnect the carrier gas supply line, split vent line, and septum purge

line (for the septum head) from the inlet. Straighten the tubing at the

manifold so that the manifold can be easily removed from the chassis.
