Guardian Liquid-cooled 40 kW Generator

‹1.8.2 GENERATOR AND LOAD COMPATIBILITY

The generator must be fully compatible with the rated voltage, number of phases and frequency of the con- nected electrical loads. The generator, connected elec- trical devices, or both, can be damaged if voltage, num- ber of phases and frequency are not compatible.

NOTE:

This manual assumes that the standby generator has been properly selected, installed and interconnected by a competent, qualified electrician or installation contractor. Once the installation is complete, do nothing that may result in noncompatibility between the generator and connected electrical loads.

1.9FUEL REQUIREMENTS

AND RECOMMENDATIONS

With LP gas, use only the vapor withdrawal system. This type of system uses the vapors formed above the liquid fuel in the storage tank.

Recommended fuels should have a Btu content of at least 1,000 Btus per cubic foot for natural gas; or at least 2,520 Btus per cubic foot for LP gas. Ask your fuel supplier for the Btu content of your fuel.

Fuel pressure for both natural gas and liquid propane setups should be 11 inches to 14 inches of water column (0.6 psi) at all load ranges.

Fuel Consumption

Gaseous fuels such as natural gas and liquid propane (LP) gas are highly explosive. Even the slightest spark can ignite such fuels and cause an explosion. No leakage of fuel is permitted. Natural gas, which is lighter than air, tends to collect in high areas; LP gas is heavier than air and tends to settle in low areas – install leak detectors accord- ingly.

‹1.9.1 CONVERSION TO LP GAS VAPOR

The generator is shipped from the factory configured for using natural gas as fuel. To convert the fuel system to LP gas, proceed as follows (Figure 1.3).

1.Remove end cap from the pressure reducer valve.

2.Turn the tension screw counterclockwise until all ten- sion is removed from the inner spring.

3.Install and tighten the end cap.

4.Invert the pressure reducer valve. In other words, turn it upside down (end cap facing downward).

5.Purge and leak test the entire fuel system according to gaseous fuel codes. NO LEAKS can appear at any point in the system.
