Natural Gas Connections
The incoming pressure must be 11 inches water column (6 oz. pressure).
Require flow rate for natural gas is 400 cubic feet per per hour.

Note: Almost all operation problems are related to the installation techniques used. Do Not guess, be sure pipe size is adequate for required flow rate.
An engine needs 10,000 BTU/hp. Natural gas provides 1,000 BTU/ft3.
1.Rotate the fuel switch (mounted on Operator Panel) to the “NAT” (Natural
2.Connect the proper size gas pipe at the input to the Natural Gas regulator. Connect the Natural Gas pipe line shown in Figure
3.Verify Fuel Supply Pressure
Prior to initial operation of generator, verify that fuel system pressure is 11″ Water Column (6 oz. pressure) and fuel pipe sizes comply with Table
4.Proceed to Engine Oil.
