What to do if the Global 5120 burner does not ignite?
- A
  ashley83Aug 5, 2025
  If the burner on your Global Portable Generator fails to ignite, there are several potential causes. It could be due to air in the fuel line, which requires purging the fuel lines. Alternatively, the gas supply pressure might be too low; ensure it's at least 69 kPa (10 psig). Other possible causes include an incorrect pressure regulator setting (adjust the pressure), a dirty fuel filter (drain the regulator sediment bowl or replace the fuel filter), a plugged orifice (replace the orifice), an incorrect air adjustment (adjust the air supply), a dirty air screen (clean the air screen), or a malfunctioning SI system (check the SI System).

Why is my Global Portable Generator output power or voltage too low?

  Rachel Paul DDSAug 13, 2025
  Low output power or voltage in your Global Portable Generator can stem from several issues. Check if the set-up voltage is correct for the site temperature. Ensure sufficient cooling around the fins by clearing any debris. Other causes include a dirty fuel filter (drain and clean or change the filter), a plugged orifice (change the orifice), a malfunctioning SO valve (check the SO valve), an incorrect air supply (adjust the air supply), a dirty air screen (clean the air screen), an incorrect fuel adjustment (adjust the fuel regulator), a limiter converter needing adjustment (check switch settings or the output voltage adjustment Pot), or a faulty power unit (check momentary open circuit voltage).

What to do if Global 5120 Portable Generator burner ignites but will not continue to burn?
- R
  Robert TurnerAug 20, 2025
  If your Global Portable Generator's burner ignites but doesn't continue to burn, it could be caused by several factors. The supply gas pressure might be too low; ensure it's at least 69 kPa (10 psig). Another possibility is an incorrect pressure regulator setting (adjust the pressure). Other potential causes include a dirty fuel filter (drain the regulator sediment bowl or replace the fuel filter), a plugged orifice (replace the orifice), a malfunctioning SO thermocouple or SO valve (check both), an incorrect air adjustment (adjust air supply), or a dirty air screen (clean the air screen).

How to fix high output power or voltage in Global 5120?
- W
  William FranklinAug 27, 2025
  If the output power or voltage of your Global Portable Generator is too high, this could be due to an incorrect fuel adjustment; in this case, you should lower the fuel pressure. It may also be caused by an incorrect Limiter Converter adjustment, so you should re-adjust the output voltage adjustment Pot.
