What the numbers mean
At 24,000 running watts
on its best fuel, this unit is sized for whole-house coverage on a typical 200 A home, subject to a load calculation by a licensed electrician.
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.
Estimated fuel cost for 24 h at ~50% load: about $73 on natural gas at
national average prices (assumptions).
Permanently installed unit: sizing, gas-line capacity, placement clearances, and
the transfer switch are a job for licensed installers under local permits.
