Possible Causes

Loose flare fittings on gas piping, Cracked flexible gas connector at generator, Leaking regulator diaphragm vent, Improperly sealed pipe threads

How to Fix / Troubleshooting

Safety first: If you smell strong gas, shut off the generator and close the main gas supply valve immediately. Do not operate electrical switches or create sparks. Evacuate the area and contact your gas utility if the smell is strong.

Steps (only if odor is faint and localized):

  • Shut off gas: Close the manual shutoff valve feeding the generator.
  • Leak detection: Apply a soap-and-water solution to all accessible joints and fittings. Bubbles indicate a leak.
  • Tighten/repair: Slightly tighten leaking flare nuts or replace damaged flexible connectors. Do not overtighten.
  • Professional test: Have a licensed gas technician perform a full leak test and pressure check before returning the generator to service.
