The Champion Power Equipment 100416 8000-Watt Tri-Fuel Portable Natural Gas Ready Generator is a reliable source of power with the flexibility you need. When you are not running your generator on natural gas, you also have the option of operating it on gasoline or propane. The ability to operate your generator on three types of fuel out of the box makes this one of the most versatile generators on the market. The EZ Start dial allows you to safely select gasoline, propane (LPG), or natural gas (NG) as your fuel source, plus a propane/natural gas selector is located on the side panel. Using natural gas, the engine produces 8750 starting watts and 7000 running watts. A 6-foot propane hose with a built-in regulator is included. To connect this generator to your home’s natural gas source, this generator includes a 25-foot NG hose kit, which includes a female quick connect end, a female flare fitting end and an NPT male adapter. Using gasoline, the 459cc Champion engine produces 10,000 starting watts and 8000 running watts, and will run for 12.5 hours at 50% load when the 8.5-gallon fuel tank is full. When using a 20-pound propane tank, it produces 9000 starting watts and 7200 running watts, and will run for 5 hours at 50% load. The electric start includes a battery, plus Cold Start Technology ensures quick cold-weather starts. With a 1.2-quart oil capacity, this unit has a low oil shut-off sensor and includes engine oil – all you need is fuel! Easily monitor power output and track maintenance intervals with Intelligauge, which allows you to keep track of voltage, frequency, session run time, and total run time to easily monitor output and track maintenance intervals. This generator has a noise level of 74 dBA from 23 feet, which is a bit louder than a vacuum. CO Shield® technology monitors the accumulation of poisonous CO gas produced by engine exhaust when the generator is running. If CO Shield® detects elevated levels of CO gas, the UL-recognized sensor will alert and shut off the engine and will illuminate a red LED. This unit meets the ANSI/PGMA G300-2018 requirements to ensure the highest level of safety and performance.
