Strong exhaust fumes or exhaust smell entering building during generator operation

Safety first: Shut down the generator immediately if exhaust fumes are detected indoors. Ventilate the area and do not re-enter until safe. Carbon monoxide is deadly.

• Inspect exhaust system: Once cool, check the exhaust manifold, flex pipe, and muffler for cracks, loose clamps, or missing gaskets. Tighten or replace components as needed.
• Verify exhaust routing: Ensure the exhaust outlet is directed away from doors, windows, vents, and soffits per Honda and local code requirements.
• Seal building penetrations: Seal any gaps where exhaust piping passes through walls or roofs to prevent fumes from re-entering.
• Consider extension kit: If necessary, have a professional install an exhaust extension kit to discharge fumes safely away from the structure.
