PC Board Removal

1. Remove the two screws at the top and bottom of the PC Board housing.
2. The PCB can now be rotated forward and out of the cabinet for access for troubleshooting purposes or for
removal of the board. There will be a plastic cover over the board, not shown here, that will need to be
removed for access.
3. To remove the PCB, disconnect all electrical harnesses. All connectors will have a latch that will need to be
released prior to disconnection. Make note of any receptacles that may not be used (3a).
4. When installing a new board ensure the dip switches are set correctly for you model and gas type.
