Code requirements for installing standby generator systems vary nationwide. We recommend having a factory-authorized dealer install your system, since they will be familiar with local and national codes, make sure the generator is properly sized, and avoid code issues with local inspectors.


This varies and depends on engine model, length of time since the last oil change, and the amount of power the generator is producing. Check the Operation Manual included with your generator for a complete list of required maintenance procedures and schedules.
