Which model this page covers
This page covers the iGen12000DFc dual fuel inverter only — not the iGen11000DFc. Westinghouse's spec table lists it as dual fuel (gasoline and propane); this page does not assign a natural gas rating.
Manufacturer figures vs. our estimates
Only the runtimes listed above are Westinghouse's own published figures. When your load and fuel amount exactly match one of them, the calculator labels the result Manufacturer Published Runtime. Loads between published figures are labeled Estimated from Manufacturer Data, and loads outside the published range are labeled Extrapolated with a wider range. Those are GeneratorRuntime estimates, not Westinghouse specifications.
Operate it safely
Like every portable generator, the iGen12000DFc must be operated according to the manufacturer's safety instructions: outdoors only, well away from doors, windows, and vents, with battery CO alarms inside your home. A CO shutoff feature is not a substitute for safe placement. Never refuel while the engine is running or hot.
