What you get: a 141cc recoil-start inverter with an RV outlet
The iGen4000DFcv is Westinghouse's 4,000-peak-watt dual-fuel inverter generator, part number 4024, with a 141cc OHV engine. Westinghouse lists it at 59 pounds dry and 21.3 by 12.6 by 19.3 inches, the same figures Amazon gives. The configuration on this listing is recoil start, and the maker's table says no battery is included.
The panel has one 120V 5-20R duplex household outlet, one 120V TT-30R RV outlet, two USB ports rated 2.1 amps, parallel outlets and an ECO switch. There is no 240V outlet. Westinghouse lists the accessories as an oil bottle, oil funnel, spark plug wrench, propane regulator and hose, and parallel cables.
Watts per fuel, run time and tank size
The manual and maker page rate it at 4,000 peak and 3,300 running watts on gasoline, and 3,600 peak and 2,970 running watts on propane, at 27.5 or about 24.8 running amps. The Amazon listing only states the gasoline figures, so size propane loads from the lower number. The manual notes output drops about 3.5 percent per 1,000 feet of altitude and about 1 percent per 10 degrees above 60°F.
Westinghouse gives run time at 25 percent load: 7 hours on gasoline and 17 hours on propane, without naming a propane cylinder size. Tank size differs between documents: the manual and product description say 1.66 gallons, while the maker's specification table and Amazon say 1.69 gallons. The difference is small, but it is two figures from the same maker.
Not CARB compliant, and a noise figure without conditions
The Westinghouse specification table answers CARB Compliant with No, and Amazon's bullets call it EPA compliant. If you live where CARB-compliant equipment is required, check before buying. The maker also lists it as not transfer switch ready, and the grounding system as a floating neutral, which the manual says may stop devices that need a grounded receptacle pin from working properly.
Westinghouse and Amazon give noise as low as 52 dBA but state no distance or load, so it cannot be compared with figures measured at 23 feet. THD is listed as 3 percent or less on the maker's table. The manual we read gives neither a decibel nor a THD figure, so both are product-page claims.
Parallel cables included, and a box list that disagrees
Parallel cables come with this model: the maker's accessory list includes them, and the manual says to use only the Westinghouse 120V parallel cable kit that came with your generator. It says to connect cables only with both units shut down, arrange the two generators in a V so exhaust heat does not melt the other case, and not to use ECO mode during parallel operation.
The manual's included list also mentions a battery charger, and its fuel-draining steps mention a battery switch, but the maker's specification table says no battery is included and the start type is recoil. Treat the manual's battery references as not applying to this recoil-start configuration, and check the box contents against Westinghouse's accessory list when it arrives.
Oil, the maintenance chart and storage
The manual says the generator ships without oil, though it may contain residual oil from factory testing, and the included bottle is for the first fill. Capacity is 0.42 quarts of 10W-30, checked before each use or every 8 hours. Gasoline must be 87 to 93 octane with no more than 10 percent ethanol; E15 and E85 damage is not covered by warranty.
The maintenance chart marks an oil change after the first 25 hours or first month and again at a later hour interval, and calls for oil changes every month under heavy load or high heat. Spark arrestor, plug, air filter, fuel filter and valve clearance also have chart intervals, with valve work recommended for a Westinghouse dealer. For storage of two to six months, drain the carburetor float bowl; beyond six months, drain the tank too.
Placement, CO shutdown and a warranty split by years
The manual says to run it only outside and far from windows, doors and vents, never in a home, garage, crawl space, truck bed or next to walls, and to keep five feet of clearance on all sides including overhead. The CO sensor shuts the engine off when CO builds up, flashes red for at least five minutes afterward, and does not replace indoor CO alarms. A yellow light is a sensor fault that only an authorized service center can repair.
Amazon's bullet describes three years of service, labor and parts coverage, but Westinghouse's written warranty for consumer use covers parts and labor for one year and replacement parts only for years two and three. Commercial or rental use gets one year. You pay transport to a service provider, prime power use is excluded, and registration or a receipt with date, model and serial number is needed.
