Generator not starting on Natural GasUpdated 5 days ago
If you happen to be having issues with your generator not starting on Natural Gas, please follow the suggested tips down below.
- Please ensure you have read the owners manual and follow the proper start up procedure for Natural Gas. (CLICK HERE) To Review Start up Procedures
- Ensure your battery is connected. As we ship our generators with the negative terminal disconnected. (CLICK HERE) On instructions how to connect battery
- Test the Battery For Voltage. Please note, the battery should read 13.5 volts when NOT under load and 11.5 to 12 volts under load.
- Inspect for leaks in the within the natural gas hose and 2nd stage regulator (located behind the panel).
- Confirm that your natural gas supply is producing the required fuel pressure to generator fuel inlet at all load ranges should be 6.0 - 9.0 in. water column for Natural Gas.
- BTU Requirements: 225,000 BTU at full load for the XP13000HXT and 278,000 BTU at full load for the XP15000HXT and lastly 295,000 BTU at full load for the XP16000iHT
- Verify the selector Fuel switch is engaged in the Natural Gas Position
- Inspect the condition of the spark plug and replace to a NGK spark plug recommended for your specific generator.
- Check for Choke Position and Operation (Please note EH will have a manual choke)
- We would recommend on doing a test with the other fuel sources for the generator. If the unit operates correctly on propane and gasoline the problem on the natural gas side would potentially be a bad fuel selector switch or incorrect pressure of natural gas going into the generator.
(DISCLAIMER) DO NOT operate engine if smell of fuel is present prior to start up
Potential Part Replacements Based off Symptoms:
Natural Gas hose Line: Damaged Fittings or leaks may require for this part to be replaced.
