3‐6 Receiving & Installation MN2408Installation The generator is completely assembled, tested and adjusted at the factory before it is shipped toyou. The procedures presented in this manual are suggestions and it is the responsibility of theOwner/Operator to arrange for these procedures to be performed by licensed contractorsaccording to all applicable codes including local codes for your Municipality/City/County andState. External connections required at the time of installation are:1. Fuel System.2. Electrical Connections - power wiring (optional transfer switch) and control wiring.3. Battery (not included).4. Ground Connection.After installation, the post installation checks must be performed prior to starting the engine.After these checks have been performed and the system operation is verified to be good, refer toSection 5 Maintenance for periodic checks that must be performed at scheduled intervals toensure continued operation with minimal problems.Fuel ConnectionsFuel selection is Natural Gas or LPV (Liquid Propane Vapor). If natural gas supply is used,follow the “Natural Gas Connections” procedure. If LPV supply is used, follow the “LP VaporConnections” procedure. Table 3‐4 defines the flow rate required for each fuel type.Table 3‐4 Fuel Consumption Natural and LPVModel Fuel Consumption at 100% loadcubic ft/Hr (cubic m/Hr)Model Fuel Consumption at 100% loadcubic ft/Hr (cubic m/Hr)Natural Gas LP Vapor Natural Gas LP VaporGLC10 348(9.9) 145.2(4.1) GLC45 584(16.5) 242(6.9)GLC15 438(12.4) 189.3(5.4) GLC50 731(20.7) 269(8.2)GLC20 528(15.0) 233.4(6.6 GLC60 780(22.1) 321(9.1)GLC25 618(17.5) 277.5(7.9) GLC80 1012(28.7) 425(12)GLC30 526(14.9) 197(5.6) GLC100 1133(32.1) 487(13.8)GLC35 575(16.3) 240(6.0) GLC125 1651(46.8) 852(16.5)General Considerations1. A generator set needs the engine to deliver 2 hp of energy to the alternator for every1000 watts of electric output power (example: an 8000 watt generator needs the engineto deliver 16 hp of energy to the generator end).2. An engine needs 10,000 BTU's of fuel energy per horsepower of engine power toprovide a sufficient supply of fuel (example: a 16 Hp engine needs 160,000 BTU's offuel energy for it to work properly). This fuel must be supplied to the regulator on thegenerator set at a pressure of 6 oz (11 inches of water column). To achieve this 6 oz.pressure in a L.P. System, you will normally have to reduce the tank pressure bymeans of a primary regulator or a regulator system of 2 or more regulators.3. There are 2,516 BTU's in one cubic foot of Propane (LP Fuel).There are 1,096 BTU's in one cubic foot of Natural Gas.4. There are 36.39 cubic feet in one gallon of Propane.There are 57.75 cubic feet in one gallon of Natural Gas.5. There are 8.58 cubic feet per pound of Propane.There are 23.56 cubic feet per pound of Natural Gas.6. When installing the piping for the gaseous fuel supply please refer to the pipe chart inTables 3‐5 and 3‐6 to be sure you are using piping of significantly large size to deliverthe necessary amount of fuel.7. If copper tubing is used, it should be “K” or “L” having a minimum wall thickness of0.032 inches. Black Iron Pipe is recommended but follow building codes for your area.The following pamphlets are available from:National Fire Protection Association (NFPA) P.O.
