Generator runs but carbon monoxide (CO) alarm in the home or near the unit frequently activates.

Safety first: If a CO alarm sounds, evacuate the building and ventilate immediately. Do not ignore CO alarms. Shut down the generator and do not restart until the cause is corrected.

• Check installation location: Verify that the WEN standby generator is installed at the minimum distance from doors, windows, and vents specified by WEN and local codes. Relocation may be required.
• Inspect exhaust system: With the engine cool, check the muffler, exhaust pipe, and joints for leaks, cracks, or loose clamps. Replace damaged exhaust components.
• Redirect exhaust (if allowed): In some installations, an approved exhaust extension kit can direct fumes away from the building. Only use WEN‑approved or code‑compliant kits.
• Consult professionals: Work with a qualified installer to ensure the generator and exhaust meet all safety requirements. Continue to use CO detectors in the home.
