Quick Answer
To switch fuels in your dual-fuel generator, check the fuel level and the generator's status lights, usually a green or yellow light indicating the primary fuel is running low. Switch to the secondary fuel when the light turns red, indicating the primary fuel is almost depleted. Typically, this occurs when the primary fuel level falls below 1-2 gallons.
Understanding Dual-Fuel Generators
Dual-fuel generators allow you to switch between natural gas and liquid propane (LP) fuel sources. This flexibility is ideal for areas where one fuel is readily available and the other has restrictions or is more expensive. To take full advantage of this feature, it’s essential to understand the fuel level monitoring system and the corresponding status lights.
Monitoring Fuel Levels
The fuel level monitoring system is usually electronic and connected to the status lights on your generator’s control panel. These lights typically follow a sequence: green (primary fuel is full), yellow (primary fuel is running low), and red (primary fuel is almost depleted). The exact sequence may vary depending on your generator model, so consult your user manual for specific guidance.
Switching Fuels
When the primary fuel level falls below 1-2 gallons, usually indicated by the yellow light, it’s time to switch to the secondary fuel source. This process typically involves opening a valve or flipping a switch on the control panel to transition from one fuel type to the other. Make sure to follow the manufacturer’s instructions and take note of any specific requirements, such as waiting for a brief period before switching to the secondary fuel.
