Possible Causes

Improper exhaust routing or clearance, Damaged or disconnected exhaust pipe, Exhaust leak at manifold or gasket, Enclosure louvers directing exhaust toward building openings

How to Fix / Troubleshooting

Safety first: Shut down the generator and ventilate the building. Carbon monoxide is deadly.

  • Inspect exhaust path: Verify the exhaust outlet is intact and directed away from doors, windows, and vents per Briggs & Stratton installation guidelines.
  • Check for leaks: Look for soot marks or noise at exhaust joints, manifold, and gaskets. Tighten or replace gaskets and clamps as needed.
  • Extend or redirect exhaust: Where allowed by code, install approved exhaust extensions to route fumes safely away from structures.
  • Re-evaluate placement: If the generator is too close to openings, consult with a professional about relocating or adding barriers.
