Recommended fluids
| Fluid | Grade | Standard | Ambient | Capacity | Notes |
|---|---|---|---|---|---|
| Fuel | Natural gas (NG) | Fuel inlet pressure measured at the fuel shut off valve while under full load must be 254 to 508 mm WC (10 to 20 in. WC). Fuel supply pressure must not exceed 635 mm WC (25 in. WC) under any conditions. Additional options in the fuel train (CSA compliance, flexible fuel connections, strainers) add restriction that must be considered when determining gas supply pressure. |
