FUEL SPECIFICATIONS AND |
CONSUMPTION REQUIREMENTS |
The engine driving the generator is engineered to provide reliable power on either Liquefied Propane Vapor (LPG) or Natural Gas. For proper operation on these fuels, it is important to deliver gas with adequate energy content, at sufficient pressure and flow rate. This generator is designed to operate on Liquefied Propane Vapor (LPG) with a minimum energy content of 2500 BTU per cubic foot or Natural Gas with a minimum energy content of 1000 BTU per cubic foot. This generator is designed to operate with a fuel pressure at the inlet of the unit between 6 and 11 inches of water column
Required fuel flow rates for specific models are given in the table below. To insure correct sizing of the piping supplying fuel to the generator set, provide the flow and pressure requirements of this section to a fuel supplier or licensed plumber during the installation planning stage. If the fuel supplier cannot guarantee delivery of fuel with these properties, the generator may not perform as advertised.
Due to differences in the energy content of fuel used, it is necessary to derate the output of the generator when connected to Natural Gas. Additionally, regional and/or seasonal variations in the makeup of the fuel can further affect output of the engine/generator system. When using Natural Gas fuel with minimum properties as defined, engine output can fall approximately 10% below that of the same set using Propane Vapor.
Per the National Gas Code (NFPA 54 - ANSI 2223.1), a manual shutoff valve in the fuel supply line to the generator is recommended.
DANGER
•All fuel system installations MUST BE done by a licensed plumber or licensed gas technician and must comply with all applicable codes, standards and regulations.
FUEL CONSUMPTION TABLE
| P120401 |
Fuel Consumption (@100% | 3.44 Gal/Hr (LP) |
load) | 280 |
All values reflect consumption at 100% rated output.
FUEL REQUIREMENTS:
For the best operation of the unit, the fuels used should have a minimum content of 1000 BTU’s per cubic foot for Natural Gas (NG) and 2520 BTU’s per Cubic foot for Liquid Propane vapor (LPG). Contact local fuel supplier for local BTU content. Fuel supply pressures must be between 4oz (6” H20 per square inch) and 6oz
(11” H20 per square inch) at the inlet to the unit.
WARNING
•Natural gas (NG) is highly explosive.
•Natural gas (NG) is lighter than air and will collect in high places.
•Liquid propane vapor (LPG) is highly explosive.
•Liquid propane vapor (LPG) is heavier than air and will collect in lower places.
•Extreme caution should be taken when working on a new installation or while performing general maintenance.
•Do not smoke when near the unit.
•Keep flames, sparks, pilot lights,
•Potential for fire or explosion always exist when using natural gas (NG) or liquid propane vapor (LPG) as a fuel source. Install this unit in compliance with all local fuel codes.
•Do Not operate engine if smell of fuel is present or other explosive conditions exist.
FUEL HOOKUP |
After electrical connections are complete, the next installation step is to connect a fuel supply to the unit. The fuel inlet fitting supplied with the generator is male 3/4" NPT. To accommodate potential settling of the generator relative to rigid supply pipeline, use of a flexible line, provided by manufacturer, in the supply line is suggested. When making connections, use only materials rated for the fuel supplied and approved for use by local, regional or national codes and/or regulatory agencies.
DANGER
•All fuel system installations MUST BE done by a licensed plumber or licensed gas technician and must comply with all applicable codes, standards and regulations.
WARNING
•Natural Gas and Propane Vapor are highly explosive gases. Check ALL fuel system connections for leaks before starting engine/generator set.
•DO NOT use a flame to check for leaks.
•Use approved equipment and methods to check for leaks.
