probe tube. Make sure the calibration tube lines up with the calibration
gas passage in each component. Apply a small amount of anti-seize
compound to the screw threads and use the screws to secure the
assembly. Torque to 4 Nám (35 in-lbs).
10. Apply anti-seize compound to the probe threads, flame arrestor hub,
and setscrews. Reinstall the flame arrestor on the probe. Using pin
spanner wrenches, torque to 14 Nám (10 ft-lbs). Secure the flame
arrestor with the locking setscrew. Torque to 2.8 Nám (25 in-lbs). If
applicable, reinstall the vee deflector, orienting apex toward gas flow.
Secure with the setscrew and anti-seize compound. Torque to 2.8 Nám
(25 in-lbs).
11. On systems equipped with an abrasive shield, install the dust seal
gaskets, with joints 180¡ apart.
