  Gas pressures are as measured at the manifold test connection.
Notice: The settings in this chart are for reference only. The actual conditions at the installation may require further 
adjustment by the fully qualifi ed and experienced start-up technician.
Notice: The light-off rate must not be set below the low fi re recommendation.  Lower rates will lengthen the time it 
takes for gas to get to the burner head and may cause ignition failures.
