FIRMAN 3200/2900 Watt Electric Start Gas and Propane Dual Fuel Portable Generator Parallel Ready CARB and cETL Certified


The FIRMAN WH02942 Inverter generator runs on either gas or liquid propane (LP) and can top out at 3200 starting watts and 2900 running watts. Power is supplied by our Max Pro Series 171cc FIRMAN engine which runs cool and efficient. Our Whisper Series muffler keeps the WH02942 running quiet –below the standards set by the National Parks Service, and our spark arrester has been approved by the USDA Forest Service. The 1.8-gallon fuel capacity provides 9 hours of run time. Starting is as simple as the push of the button with the reliability of our first-pull recoil system.

For the ultimate in portability the WH02942 has a built-in handle and wheel kit.  Major touch points are all front and center for easy starting and use – power, choke, eco-mode and all receptacles are conveniently located for easy access. The durable, lightweight, powerful inverter is built for years of use.  Just add gas or liquid propane (LP)! Everything you need comes standard in the box including: oil, funnel, owner’s manual, trickle charger, battery charger cable, and spark plug wrench.

Finally, we back what we build with our legendary limited lifetime warranty.
