Prior to Start-Up
Note: The Intelis Gas Meter is shipped from the factory with the shutoff valve in the open pos-
ition. Verify the valve is open prior to installing the meter. Confirm the open valve icon is dis-
played on the LCD display and that the valve closed icon is not displaying.
Perform a visual check of the inside of the meter outlet to also verify the shutoff valve is open.
Before the Intelis Gas Meter start-up:
■
Read the meter badge data regarding maximum allowable operating pressure (MAOP) and
capacity flow rate to be sure the meter meets the installation requirements.
■
Sight across both swivel flanges or test with a suitable level to determine that the flanges are
nominally in the same plane and will not cause excessive strain on the meter or piping when
the connection nuts are tightened.
Start-Up
1. Blow out the service lines before the meter is installed to ensure no dirt, debris, or liquids of
any kind will be carried into the meter when the gas is flowing in the line.
2. Place a new connection nut washer (gasket) on each connect nut or meter hub.
3. Support the meter so that both hubs are against the connection washers and run the con-
nection nuts down hand tight.
4. In an alternating fashion, tighten the nuts to the appropriate torque for the connection size.
5. Check the meter's downstream system to ensure that all connections are leak free or that
the downstream valve, if one is present, is closed.
6. Open the upstream and downstream valves very slowly to prevent any pressure surges into
or out of the meter.
