1.12 FUEL CONSUMPTION

15 kW Models

Using Natural Gas

........................................236 cu. ft. per hour

Using LP Gas

92 cu. ft. per hour

20 kW Models

 

Using Natural Gas

........................................307 cu. ft. per hour

Using LP Gas

122 cu. ft. per hour

25 kW Models

 

Using Natural Gas

........................................441 cu. ft. per hour

Using LP Gas

175 cu. ft. per hour

 

NOTE:

Fuel consumption is given at rated maximum con- tinuous power output when using natural gas rated at 1000 Btu per cubic foot; or LP gas rated 2520 Btu per cubic foot. Actual fuel consumption obtained may vary depending on such variables as applied load, ambient temperature, engine condi- tions and other environmental factors.

Fuel pressure for a natural gas set up should be five inches to 14 inches of water column (0.18 to 0.5 psi) at all load ranges.

Fuel pressure for an LP vapor set up should be 11 inches to 14 inches of water column (0.4 to 0.5 psi) at all load ranges.

1.13RECONFIGURING THE FUEL SYSTEM FOR LP VAPOR

NOTE:

All models are configured for natural gas (NG) from the factory.

To reconfigure the fuel system from NG to LP vapor, follow these steps:

1. Turn the main gas supply off.

*Rated power of generator is subject to and limited by such factors as ambient temperature, altitude, engine condition, and other fac- tors. Engine power will decrease about 3.5% for each 1000 feet above sea level and will decrease an additional 1% for each 10°F above 60°F. Maximum output power of the generator is limited by maximum engine power.

Generac has long been recognized as a leader in backup power solutions, and its 005031-0 (25kW) and 005030-0 (15kW) home standby generators exemplify the brand's commitment to reliability and performance. Designed for residential use, these generators provide peace of mind during outages, ensuring that homes remain powered even in the most challenging conditions.

One of the standout features of both models is their advanced Generac G-Force engine, which is engineered for longevity and impressive power output. The G-Force engine is built from the ground up for generator use, refined to handle the unique demands of continuous operation. This results in a highly durable system that requires little to no maintenance, making it a favored choice for homeowners looking for a reliable energy solution.

Another important characteristic is the True Power technology featured in both generators. This technology delivers clean, stable power that is safe for sensitive electronics and appliances. It ensures that devices such as computers and medical equipment operate smoothly without the risk of damage from power fluctuations. Additionally, the Generac 005031-0 and 005030-0 generators are equipped with the Quiet-Test mode, allowing them to run at lower RPMs during routine weekly self-tests. This innovation significantly reduces the noise produced during tests, making it less disruptive for residents.

Furthermore, these generators come with a user-friendly interface and a mobile link app, enabling homeowners to monitor their generator's performance remotely via a smartphone. This feature enhances convenience, allowing users to receive alerts and notifications about their generator's status, maintenance needs, and operation conditions right from their devices.

Both the 25kW and 15kW models are also designed with a robust transfer switch, which seamlessly shifts power from the grid to the generator in case of any outages. This automatic transfer feature ensures that homes maintain power without needing manual intervention, making them ideal for those who want uninterrupted electricity.

In terms of fuel source, both models operate on natural gas or propane, providing flexibility to homeowners regarding fuel availability and preferences. With excellent warranty options and Generac's reputation for quality, both the 005031-0 (25kW) and 005030-0 (15kW) generators stand as dependable choices for safeguarding homes from the unpredictability of power outages.
