3.7.4.4 Converting From Natural Gas to Propane (Vapor Withdrawal)
The generator set leaves the factory set up for Natural gas.
For use with Propane, the generator must be converted by configuring the control for
Propane.
3.7.5 Testing the Fuel System for Leaks
WARNING: Fuel presents the hazard of explosion or fire which can result in severe
personal injury or death. Do not smoke or allow any flame, spark, pilot light,
arc-producing equipment, switch or other ignition sources around fuel or fuel
components.
Before operating the generator set, test the fuel system for leaks.
· Energize the fuel solenoid from a separate 12-volt DC source before testing the fuel
system
NOTE: Testing for gas leaks with a flame can cause a fire or explosion that can lead
to severe personal injury or death. Use approved methods only.
