FIRMAN Tri Fuel Portable Generator 11400W Electric Start 120V/240V with CO Alert


Description

The FIRMAN T09275 is a heavy-duty tri-fuel portable generator engineered to deliver serious power wherever and whenever you need it most. With the ability to run on gasoline, propane (LPG), or natural gas (NG), this generator gives you unmatched fuel flexibility for home backup, job sites, farms, and large outdoor events. Producing up to 11,400 starting watts and 9,200 running watts on gasoline, it's powerful enough to serve as a portable alternative to a whole-home standby generator when paired with a transfer switch.

At the heart of this machine is a robust 459cc FIRMAN engine with a cast iron sleeve, built to handle years of demanding use without breaking down. A 9-gallon steel fuel tank provides up to 11 hours of runtime at 50% load, and the electric start means you're up and running quickly - even in an emergency. The CO Alert system adds an essential layer of safety, monitoring for dangerous carbon monoxide levels and helping protect your family or crew.

FAQ

What is the difference between starting watts and running watts?

Starting watts (also called peak or surge watts) is the extra power the generator briefly provides to start motor-driven appliances like refrigerators, air conditioners, and pumps - which require a surge of electricity to get running. Running watts is the continuous power the generator sustains during normal operation. For the T09275, that's 11,400 starting and 9,200 running watts on gasoline. When sizing your generator, make sure your total running wattage needs stay under the running watts rating.

Can I connect this generator to my home's natural gas line?

Yes - the T09275 is designed to run on natural gas (NG) in addition to gasoline and propane. When connected to a natural gas line, it produces 8,650 starting watts and 6,900 running watts. This is especially convenient for extended outages since you won't need to store or refill fuel. You'll need the appropriate NG regulator and a qualified technician to make the connection safely.

How does the CO Alert system work?

The CO Alert system continuously monitors the surrounding air for dangerous levels of carbon monoxide gas. If CO reaches a hazardous concentration, the system triggers an alert to warn you and can initiate a shutdown. This is an important safety feature - carbon monoxide is colorless and odorless, and generator exhaust is a common source. Always operate this generator outdoors and well away from windows, doors, and vents regardless of the CO sensor.

Do I need a transfer switch to use this generator for home backup?

Yes - to safely power your home's circuits during an outage, you should use a properly installed transfer switch. This prevents dangerous back-feeding of electricity onto utility lines, which can injure utility workers and damage your generator. The T09275's L14-30R and 14-50R outlets are designed to work with standard transfer switch setups. Consult a licensed electrician for installation.

Is this generator available for sale in California?

No - this product is not CARB certified and cannot be shipped to California. It is EPA certified and available for sale in all other U.S. states. If you're in California, please contact us and we can help you find a CARB-compliant alternative.

How is this generator shipped, and will I need to assemble it?

The T09275 ships in a carton weighing approximately 241 lbs, typically via freight carrier. Minimal assembly is required upon arrival - primarily adding oil, attaching the wheel kit, and connecting the handle. All necessary tools and an oil bottle are included in the box. Please email service@omahasportsandgames.com if you have questions about your specific delivery.
