2. Unscrew one index mounting screw completely. Hold one hand under the index to catch the screw. While
removing the other mounting screw, pull the index away from the meter to keep the index backplate
against the back of the screw. Remove the screw completely after the index is free of the meter.
Set the index aside where it will not be damaged or fill with dirt, rain or snow. The index will be mounted
in the endpoint later in this procedure. Discard the index mounting screws. The 100G Datalogging gas
endpoint for National/Lancaster meters includes new, different-sized index mounting screws (see
Installation Prerequisites on page 7 for screw information).
3. Remove the old gasket, gasket residue, and dirt from the meter (if applicable). The meter face must be free
of gasket residue or dirt before you install the 100G Datalogging gas endpoint assembly.
4. Verify the meter drive dog points straight out from the meter.
