Recommended fuels should have a Btu content of at least 1,000 Btus per cubic foot for natural gas and at least 2,520 Btus per cubic foot for LP gas. Ask the fuel supplier for the Btu content of the fuel being used.

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.

Gaseous fuels such as natural and LP

!(propane) gas are highly explosive. Even the slightest spark can ignite such fuels and cause an explosion. No leakage of fuel is permitted. Natural gas, which is lighter than air, tends to collect in high areas. LP gas is heavier than air and tends to settle in low areas.

1.7ENGINE PROTECTIVE DEVICES

The engine has several safety switches which cause the engine to automatically shut down under the fol- lowing conditions: low oil pressure, high coolant tem- perature, engine overspeed, low coolant level or over- crank (Figure 1.3).

Figure 1.3 - Engine Protective Devices

‹1.7.1 LOW OIL PRESSURE SWITCH

This switch is normally-closed (N.C.), but is held open by engine oil pressure during engine running. Should operating oil pressure drop below about 8-10 psi (55-68 kPa), the switch contacts close and the engine shuts down automatically (Figure 1.4).

Figure 1.4 - Low Oil Pressure Switch

‹1.7.2 HIGH COOLANT TEMPERATURE SWITCH

This normally open (N.O.), thermostatic switch has sensing tip which is immersed in captive coolant. Should coolant temperature exceed about 230°F (110°C), the switch contacts close, which causes the engine to shut down automatically (Figure 1.5).

Figure 1.5- High Coolant Temperature Switch

‹1.7.3 LOW COOLANT LEVEL SWITCH

Should engine coolant level drop below the level of the high coolant temperature switch, it is possible for the engine to overheat without automatic shutdown. To prevent such overheating without automatic shut down, the engine has a low coolant level sensor. If the engine coolant drops too low, the engine automatical- ly shuts down (Figure 1.6 on page 6).

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.
