Generac is phasing out the 7174 13kW Generac Guardian with 100-Amp 16-Circuit Automatic Transfer Switch in favor of a new, more powerful 14kW Generator. The 7224 uses the same purpose-built G-Force 800-Series Engine as the 7174, with spiny-loc cast-iron cylinder walls, hydraulic lifters, and fully pressurized lubrication system. Expect the same long-life and reliable performance from all Generac Guardian Series Generators backed by a 5-year limited warranty. Designed, Engineered, and Manufactured in Wisconsin USA with a Wisconsin based Customer Support Center staffed 24/7, 365 days a year.
