What is the difference between the FIRMAN T07573 and a dual-fuel generator?

The T07573 adds natural gas capability, so you can connect it to a home's gas line for continuous fuel without storing propane tanks. Dual-fuel models typically only support gasoline and propane.

Can the T07573 power a whole house?

With a transfer switch, it can provide backup power for essential circuits, but it may not handle the entire load of a large home simultaneously. Manage high-draw appliances carefully.

How loud is the FIRMAN T07573?

It is relatively loud, typical of open-frame generators, and may not be suitable for quiet neighborhoods without noise mitigation.

What is included in the box?

The generator comes with a wheel kit, handle, oil funnel, and a propane hose/regulator. A battery for the electric start is usually included.

Does the CO Alert shut off the generator automatically?

Yes, the CO Alert system detects dangerous carbon monoxide levels and shuts down the generator to prevent poisoning.
