INSTALLATION

THE GASEOUS FUEL SYSTEM

WARNING

Propane and Natural Gas are extremely flammable and explosive.

Fire or explosion can cause severe burns or death.

•LP gas is heavier than air and will settle in low areas.

•Natural gas is lighter than air and will collect in high areas.

•The slightest spark can ignite these fuels and cause an explosion.

The information provided below is to assist gaseous fuel system technicians in planning installations. In no way should this information be interpreted to conflict with applicable fuel gas codes. Consult with your local fuel supplier or Fire Marshall if questions or problems arise.

TO THE INSTALLER: Consult with the Home Generator System owner(s) and convey any technical considerations that might affect their installation plans before applying these general guidelines.

The following general rules apply to gaseous fuel system piping:

•The piping should be of a material that conforms to federal and local codes, rigidly mounted and protected against vibration.

•Piping should be protected from physical damage where it passes through flower beds, shrub beds, and other cultivated areas where damage could occur.

•Install the flexible, gaseous hose (supplied) between the Home Generator System Fuel Inlet port and rigid piping to prevent thermal expansion or contraction from causing excessive stress on the piping material.

CAUTION

The supplied flexible gaseous pipe is not to be installed underground or in contact with the ground.

•The entire flexible gaseous pipe must be visible for periodic inspection and must not be concealed within, contact, or run through any wall, floor, or partition.

NOTE: Where local conditions include earthquake, tornado, unstable ground, or flood hazards, special consideration shall be given to increase strength and flexibility of piping supports and connections.

•Piping must be of the correct size to maintain the required supply pressures and volume flow under varying generator load conditions with all gas appliances connected to the fuel system turned on and operating.

•Use an approved pipe sealant or joint compound on all threaded fittings to reduce the possibility of leakage.

•Installed piping must be properly purged and leak tested, in accordance with applicable codes and standards.

WARNING

Propane and Natural Gas is extremely flammable and explosive.

Fire or explosion can cause severe burns or death.

•Before placing the Home Generator System into service, the fuel system lines must be properly purged and leak tested.

•NO leakage is permitted.

Consider the following factors when planning to install the fuel supply system:

The Home Generator System engine is fitted with a fuel mixer system that meets the specifications of the California Air Resources Board for “tamper-proof” dual fuel systems. The unit will run on natural gas or liquefied propane vapor.

•A minimum of one accessible, approved manual shutoff valve shall be installed in the fuel supply line within 6 ft (1.8 m) of the Home Generator System. A union or flanged connection shall be provided downstream from this valve to permit removal of controls.

•Natural gas fuel supply pressure at the generator's fuel inlet port should be between 5 to 7 inches of water (in. W.C.) at full load. LP fuel supply pressure should be 11 to 14 inches of water (in.W.C.) at full load.

40221 specifications

The Briggs & Stratton 40221 is a prominent model of portable generator that is well-regarded for its reliability, performance, and innovative features. Designed for both home and professional use, this generator stands out due to its robust construction and versatile applications, making it an excellent choice for homeowners, contractors, and outdoor enthusiasts alike.

One of the main features of the Briggs & Stratton 40221 is its powerful 305cc engine, which delivers a notable output of 3,250 running watts and a peak wattage of 3,750 watts. This capacity ensures that it can effectively power essential appliances during outages or provide energy for tools and equipment on job sites. The generator’s ability to handle a variety of loads makes it suitable for a range of applications, from powering refrigerators and lights to operating power tools.

The Briggs & Stratton 40221 utilizes advanced inverter technology, which is designed to produce clean and stable power. This technology allows users to safely run sensitive electronics such as laptops and smartphones without the risk of damage. The inverter system also provides excellent fuel efficiency, meaning users can run the generator longer on a single tank of gas, enhancing convenience and cost-effectiveness.

Another key characteristic of the 40221 is its lightweight and portable design. Equipped with convenient folding handles and solid rubber wheels, it can be easily transported to job sites, campsites, or stored away during periods of non-use. The generator’s compact frame doesn’t compromise its durability; it is built to withstand outdoor conditions, thanks to its reinforced structure and weather-resistant design.

Safety features are a fundamental aspect of the Briggs & Stratton 40221. It comes with an Automatic Voltage Regulation (AVR) system that helps maintain consistent power output while protecting connected devices from voltage spikes. Additionally, it includes built-in circuit breakers to prevent overload and a low-oil shutdown feature, which stops the engine to avoid damage when oil levels get too low.

The Briggs & Stratton 40221 is equipped with multiple outlets, including 120V AC outlets and a 12V DC outlet for straightforward connectivity to various devices. With user-friendly controls and a clear display for monitoring fuel levels and runtime, this generator is designed for ease of use, appealing to both seasoned and novice users.

In summary, the Briggs & Stratton 40221 combines power, efficiency, portability, and durability into a single unit, making it a practical choice for anyone needing reliable backup power or on-the-go energy solutions. Whether for emergencies or everyday use, it delivers dependable performance that stands the test of time.
