Baldor Series PC Mutlifuel manual LP Gas Connections

LP Gas Connections

The LPG connections should only be made if your generator is setup to run on LPG. If it is setup to run on Natural Gas, contact your Baldor representative and do not continue with installation.

The incoming pressure must be 11 inches water column (6 oz. pressure).

Required flow rate for LP gas is 158 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. LP gas provides 2,516 BTU/ft3 (or 91,547 BTU/gallon).

1.Rotate the fuel switch (mounted on Operator Panel) to the “LPG” (Propane–CCW) position.

2.Connect the proper size gas pipe at the input to the LP Gas regulator. Connect the LPG pipe line shown in Figure 3-4 using the correct size pipe for the required flow rate and length of pipe. Refer to Table 3-2 for pipe size. Be certain that all connections are sealed and no leaks are present. The installer must ensure that all gas connections comply with all building codes.

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 3-2.

4.Proceed to Engine Oil.
