During reassembly, apply high-temperature, anti-seize lubricant to the
threads of the igniter-injector and grounding screw. Also, ensure that the
igniter-injector are properly positioned and are not contacting other
components. Torque the igniter-injector to 15 ft-lbs (20.34 Nm).
18. Reinstall all components in the reverse order in which they were removed, beginning with
the exhaust manifold assembly removed in step 15.
19. When attaching the intake manifold to the exhaust manifold (removed in step 11), torque
the six 5/16 hex nuts to 12 ft-lbs (.
The manifold-to-heat exchanger gasket must be held in place with High
Temp RTV Silicone sealant. The exhaust manifold must be carefully
raised into place, centered, and leveled to insure the gasket makes a
good seal between the manifold and heat exchanger.
20. Reinstall the exhaust vent onto the exhaust manifold using a High Temp Red RTV silicon
sealant, such as sealants available from Permatex or Loctite.
21. Start the unit and fire it for approximately 20 minutes, to bring it up to working temperature,
then shut it down and re-torque the six 5/16 hex nuts attaching the intake manifold to the
exhaust manifold (see step 19) to 146 in/lbs.
