FUEL REQUIREMENTS

The Stationary Emergency Generator may be equipped with one of the following fuel systems:

•Natural gas fuel system

•Propane vapor (LPV) fuel system

Recommended fuels should have a Btu content of at least 1,000 Btu's per cubic foot for natural gas; or at least 2,520 Btu's per cubic foot for LP gas. Ask the fuel supplier for the Btu content of the fuel.

NOTE:

The fuel consumption requirements are identified in the Specifications section of the Owner's Manual. Refer to the Installation Manual if assistance is required for the sizing of the pipe diameter for the generator. Any piping used to connect the generator to the fuel supply should be of adequate size to achieve the 100% load fuel consumption requirements identi- fied in the Specifications section regardless of actual load.

NOTE:

The recommended fuel pressure is identified in the Specifications section this manual.

NOTE:

It is the responsibility of the installer to make sure that only the correct recommended fuel is supplied to the generator fuel system. Thereafter, the owner/operator must make certain that only the proper fuel is supplied.

NATURAL GAS FUEL SYSTEM

Natural gas is supplied in its vapor state. In most cases, the gas distribution company provides piping from the main gas distribu- tion line to the standby generator site. The following information applies to natural gas fuel systems.

•Gas pressure in a building is usually regulated by national, state and local codes.

•To reduce gas pressure to a safe level before the gas enters a building, a primary regulator is needed. The natural gas supplier may or may not supply such a regulator.

•It is the responsibility of the gas supplier to make sure sufficient gas pressure is available to operate the primary regulator.

•Gas pressure at the inlet to the fuel shutoff solenoid must never exceed approximately 14 inches water column (0.5 psi).

PROPANE VAPOR WITHDRAWAL FUEL SYSTEM

This type of system utilizes the vapors formed above the liquid fuel in the supply tank. Approximately 10 to 20 percent of the tank capacity is needed for fuel expansion from the liquid to the vapor state. The vapor withdrawal system is generally best suited for smaller engines that require less fuel. The installer should be aware of the following:

•When ambient temperatures are low and engine fuel consump- tion is high, the vapor withdrawal system may not function efficiently.

•Ambient temperatures around the supply tank must be high enough to sustain adequate vaporization, or the system will not deliver the needed fuel volume.

•In addition to the cooling effects of ambient air, the vaporization process itself provides an additional cooling effect.

QT06024ANAX, QT06024AVSX, QT06024ANSX, QT06024AVAX specifications

The Generac QT06024AVAX, QT06024ANSX, QT06024AVSX, and QT06024ANAX are powerful and versatile residential generators designed for those who want the peace of mind provided by reliable backup power. These models from Generac's Guardian Series are engineered for performance, efficiency, and ease of use, making them ideal solutions for homeowners looking to ensure uninterrupted power during outages.

One of the standout features of these generators is their robust 60 kW capacity, which allows them to power essential home appliances, HVAC systems, and even larger electricity-demanding devices without a hitch. This capacity makes them suitable for medium to large homes, providing enough energy to keep daily operations running smoothly even during extended outages.

The QT series incorporates Generac's advanced Quiet-Test technology, which reduces noise levels during self-testing. This feature enables the generator to perform regular self-diagnostic tests at a much quieter decibel level, ensuring it does not disrupt the household during these checks. Additionally, the generators are designed with a weather-resistant enclosure, providing durability and protection against various environmental conditions.

The models are equipped with an intuitive control panel featuring a user-friendly digital display that allows for easy monitoring of power usage and system status. They also feature an automatic transfer switch that seamlessly switches from grid power to generator power in case of an outage, ensuring that the transition is almost instantaneous and worry-free for homeowners.

Moreover, the QT series generators utilize a liquid-cooled engine, which provides greater efficiency and performance compared to air-cooled alternatives. This technology not only ensures longer run times but also contributes to a longer lifespan for the generator. The low-oil pressure shutdown feature is another critical safety aspect, protecting the engine from damage by automatically shutting it down when oil levels are too low.

Finally, these models are designed with flexibility in mind. They can be customized with various accessories and options to meet specific homeowner needs. Whether for full home backup or partial power, the Generac QT06024AVAX, QT06024ANSX, QT06024AVSX, and QT06024ANAX are reliable solutions that give homeowners the confidence to weather any storm without losing power. With their combination of advanced technology, powerful performance, and user-friendly features, Generac continues to set the standard in home standby power solutions.
