Strong exhaust fumes or heat felt inside nearby building when generator runs

Safety first: Carbon monoxide is deadly. If fumes are detected indoors, shut down the generator immediately and ventilate the building.

• Step 1 – Inspect exhaust routing: Verify that the exhaust outlet is directed away from building openings and meets local code clearances.
• Step 2 – Check joints and gaskets: With the engine cool, inspect exhaust flanges, flex connections, and muffler joints for soot marks indicating leaks. Tighten bolts and replace gaskets as needed.
• Step 3 – Replace damaged components: Replace cracked mufflers or flex pipes with Multiquip‑approved parts.
• Step 4 – Seal enclosure penetrations: Seal gaps where exhaust or conduits pass through walls to prevent fumes from entering the building.
• Step 5 – Install CO detectors: Ensure carbon monoxide detectors are installed and functioning in occupied spaces.
