NOTE:

Fuel consumption is given at rated maximum con- tinuous power output when using natural gas rated at 1000 Btu per cubic foot and 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 both natural gas and liquid propane set ups should be 11 inches to 14 inches of water column (0.6 psi) at all load ranges.

NOTE:

A seperate gas line and regulator may be needed to assure proper gas pressure (11-14”) to the gen- erator. Low gas pressure can cause hard starting and could affect engine durability.

1.12RECONFIGURING THE FUEL SYSTEM

NOTE:

All models are configured for natural gas from the factory.

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

1.Turn the main gas supply off.

2.Remove the carburetor fuel hose from the outlet port (Port 1) of the demand regulator (Figure 1.8).

3.Remove the brass hose fitting from the outlet port (Port 1) of the demand regulator.

4.Remove pipe plug from Port 2.

5.Install brass hose fitting into Port 2.

6.Install pipe plug into Port 1.

7.Connect carburetor gas hose to brass fitting.

8.Tighten all clamps and plugs.

9.Make sure fuel supply is of the proper pressure and type for configuration.

10.Reverse the procedure to convert back to natural gas.

Generac is renowned for its innovation in the power generation industry, and their range of generators—including models 0047210, 0047220, 0047230, 0047240, 0047250, 0047251, 0047252, 0047253, and 0047260—showcase advanced technologies and functionality that meet diverse power needs.

One of the standout features of these models is the use of Generac’s G-Force Engine, specifically designed for reliability and longevity. This engine is notorious for its durability, capable of handling demanding workloads and proving to be more efficient than typical engines found in similar generators. It provides quick start times, lower emissions, and is built to withstand extended operational cycles.

Another notable technology in these models is the Quiet-Test™ mode, which enables the generator to run at a lower RPM while it performs an exercise routine. This feature not only reduces noise during operation but also conserves fuel, making it an eco-friendly option that doesn’t compromise on performance.

The generators are equipped with advanced monitoring and control features, including the Mobile Link™ application compatibility. This allows users to monitor the status of their generator remotely via a smartphone or tablet, offering peace of mind and real-time access to the generator's operational functioning. This connectivity also enables the user to receive alerts and notifications about maintenance needs or when the generator is in need of attention.

In terms of design, these models boast a robust steel enclosure that offers superior protection against the elements, thereby enhancing durability and ensuring efficient operation regardless of weather conditions. The enclosures also come with a weather-resistant finish, making them suitable for outdoor installation.

Moreover, the generators feature a well-thought-out installation process with easily accessible controls and noise-reduction technology, which helps minimize disturbances for residential applications. They also offer multiple power outputs, catering to varied energy needs, from essential home appliances to larger devices.

Safety is a core consideration with Generac models, and features such as the automatic shutdown mechanism prevent overheating, ensuring operational safety during use. Coupled with an efficient fuel consumption rate, these generators stand out as impeccable solutions for power backup in homes and businesses alike.

The series exemplifies Generac’s commitment to excellence in power solutions, integrating user-friendly technology, efficient performance, and top-tier safety into compact, durable designs. Users can rely on models 0047210 to 0047260 for dependable power generation tailored to their specific needs.
