Which direction should generator exhaust point to keep a home safe?

✓ Accepted answer

Always point the exhaust stream of a portable generator directly away from the building's exterior walls, windows, and ventilation openings.

• Direct the exhaust outward: Position the generator so that the exhaust pipe is angled away from the house. This prevents carbon monoxide, an odorless and deadly gas, from being sucked into the home or accumulating in enclosed spaces like garages.
• Maintain a 20-foot buffer: Safety experts and FEMA recommend placing the unit at least 20 feet (6.1 meters) from your home, windows, and doorways. This distance ensures that exhaust gases disperse into the open atmosphere rather than lingering near air intakes.
• Protect HVAC systems: Ensure the exhaust path does not align with heating or cooling vents, crawl space vents, or garage openings. In many homes, the HVAC system creates negative pressure, which can draw dangerous fumes indoors even if the generator is technically outside the walls.
• Account for wind direction: Check the wind forecast before starting the engine. If the wind is blowing toward your home, relocate the generator to the downwind side of the property to prevent exhaust backflow toward living areas.
• Use automated shut-off features: As of 2026, new federal regulations from the Consumer Product Safety Commission are phasing in requirements for generators to automatically shut off if carbon monoxide levels reach dangerous thresholds near the unit. Ensure your model includes this safety sensor for added protection.
