Use only approved components in the fuel sup- ply system. All components must be properly installed in accordance with applicable codes. Improper installation or use of unauthorized components may result in fire or an explosion. Follow approved methods to test the system for leaks. No leakage is permitted. Do not allow fuel vapors to enter the vehicle interior.

2.3.2 TESTING THE INSTALLATION
The manufacturer recommends testing the installa- tion to be sure adequate cooling airflow is available to the unit before placing the unit into service. If the unit shows signs of overheating, enlarge the air openings. Never place a unit into service until absolutely certain that cooling and ventilation is adequate.
NOTE:
Test the installation, especially if bringing in air from below the generator set.
2.4LP Gas Fuel System
danger
LP gas is highly explosive. The gas is heavier than air and tends to settle in low areas. Even the slightest spark can ignite it and cause and explosion. Only competent, qualified people should be allowed to install, test, adjust or ser- vice an LP gas fuel system. Install the optional fuel system in compliance with applicable codes, standards and regulations. After the installa- tion, do not do anything that might render the system in noncompliance with applicable codes and standards.
The LP powered range of generators are fitted with a nonadjustable, factory set system. These systems are
2.4.1 Parts not Included in Fuel System
The propane fuel system does NOT include such items as (a) gas tank, (b) gas piping, (c) fittings, (d) valves, and (e) primary regulator, used to store the gaseous fuel and deliver it to the gaseous fuel sole- noid (Figure 2.9).
2.4.2 SOME IMPORTANT CONSIDERATIONS
When installing an LP gas system, consider seriously the following items:
•All fittings, lines, hoses and clamps must be tight and free of leaks. Apply a pipe sealant to threads when assembling threaded connections. This reduces the possibility of leakage.
•Test the entire fuel system for leaks using approved test methods.
•Optimum gas pressure at the inlet to the gaseous fuel solenoid valve and secondary regulator is 11 inches water column.
•The installer’s fuel supply connection point is at the gaseous fuel solenoid valve. This is a
