Manifold Assembly Removal - Rinnai RUC80i Training Program

Manifold Assembly Removal

1. Disconnect the wiring and remove the thermocouple as outlined on the previous slide
glass plate can stay in place)
2. Disconnect the wiring harnesses from the solenoid valves: SV1 (black & blue), SV2 (black &
yellow), SV3 (black & red).
3. Disconnect the gas supply pipe by removing the single screw holding the retaining clip.
Remove the clip and pull the gas line to the right until is clears the manifold. Ensure the o-ring
is intact. (for reassembly, ensure the o-ring is on the supply pipe and not inside the manifold
opening. This will reduce the possibility of the o-ring being cut upon reassembly.
4. Remove the 10 screws
securing the manifold to
the burner assembly.
5. Pull the manifold forward
away from the unit.
6. Inspect the gasket
underneath for any
damage.
