3‐8 Receiving & Installation MN2408Example: Determining Pipe Size for LPVA generator has a 16Hp engine 60 feet from the supply.Determine the supply pipe size for Natural Gas fuel.16 x 10,000 = 160,000 BTU's / per hour for proper operation.160, 0002, 516 63.5cubicfeetperhour.From Table 3‐6, a 60 foot run requires a minimum 1” pipe at full engine load.LP Vapor Connections (vapor withdrawal only)The LPV connections should only be made if your generator is setup to run on LPV. If it is setupto run on Natural Gas, contact your Baldor representative and do not continue with installation.The incoming pressure must be 11 inches water column (6 oz. pressure).Table 3‐6 LP Vapor Flow Rate (Cubic Feet per Hour) per Pipe LengthPipeLength(Feet)Iron Pipe Size1 /2″ 3 /4″ 1″ 1- 1 /4″ 1- 1 /2″ 2″ 2- 1 /2″ 3″ 4″ 6″ 8″15 48 109 218 475 772 1570 2437 4115 8786 24497 5000730 33 76 153 339 538 1127 1741 2975 6140 17325 3535345 27 63 126 275 443 934 1456 2469 5001 14781 2886560 24 54 110 241 386 817 1266 2184 4304 12236 2500475 49 98 218 345 709 1108 1899 3798 10957 2234590 44 89 196 310 633 987 1709 3482 10001 20414105 41 83 180 285 582 905 1551 3228 9254 18895120 76 171 266 544 848 1456 3038 8659 17673150 69 153 241 494 772 1323 2754 7748 15825180 63 142 222 456 709 1234 2532 7064 14432210 58 130 202 418 652 1127 2342 6439 13356240 120 190 393 614 1063 2209 6077 12405270 113 180 367 576 1000 2057 5697 11780300 108 171 345 544 943 1899 5381 11179Note: Almost all operation problems are related to the installation techniques used.Do Not guess, be sure pipe size is adequate for required flow rate.1. Connect the proper size gas pipe at the input to the LP Vapor regulator. Connect theLPV pipe line shown in Figure 3‐3 using the correct size pipe for the required flow rateand length of pipe. Refer to Table 3‐6 for pipe size. Be certain that all connections aresealed and no leaks are present. The installer must ensure that all gas connectionscomply with all building codes.2. Verify Fuel Supply PressurePrior to initial operation of generator, verify that fuel system pressure is 11″ WaterColumn (6 oz. pressure) and fuel pipe sizes comply with Table 3‐6.3. Proceed to Electrical Connections.
