What the numbers mean
- At 13,000 running watts on its best fuel, this unit covers most household circuits through an appropriately sized transfer switch; central air conditioning typically needs load management or a soft starter.
- Runs on natural gas, propane — expect lower output on propane (roughly 10%) and natural gas (roughly 20%) than on gasoline; the spec table shows the published per-fuel ratings.
- Permanently installed unit: sizing, gas-line capacity, placement clearances, and the transfer switch are a job for licensed installers under local permits.
