| CO Alert | The CO Alert is triggering with a solid yellow light while the generator is running. The manual lists this as a cause of the generator shutting down. | Contact technical support for further assistance. Call service if it persists. | 77 |
| Overload | The generator overload light is on, meaning the AC load on the generator is too high for it to supply. | Reduce the AC load on the generator. Then turn the generator OFF and back ON again to reset it. | 79 |

FAQ
How long does the DuroMax XP13500iH run on a tank?
The maker rates it at 10.8 hours at 50 % load (about 5,250 W) on a 8.0-gal tank. A light load such as a refrigerator and lights runs longer; a full load runs shorter.
Can the DuroMax XP13500iH start a sump pump or well pump?
Starting surge matters more than running watts: this unit is rated 13500 W peak. That covers a typical 1/2 HP sump pump (about 2150 W to start). Use the calculator with your exact pump.
