Unpacking and Inspection Section 2 2.1 — General NOTE: After unpacking, carefully inspect the contents for damage. Thoroughly inspect the unit immediately upon delivery to determine if any damage occurred in transit. Any claims for shipping damage need to be filed with the freight carrier as soon as possible.
Unpacking and Inspection 2.3 — Unpacking Remove shipping carton. See Figure 2-1. Wooden Frame 15 kW Generator Figure 2-1. Unpack Generator Remove four bolts with crating clamps. Carefully lift the generator off the wooden pallet. Do NOT drag the gener- ator off the pallet or damage to the base will occur.

Site Selection and Preparation Section 3 3.1 — Site Selection No operable windows or openings in the wall permitted within 5 ft (1.52 m) from any point of the generator. Existing Wall 18 in (457 mm) 60 in (1524 mm) 60 in (1524 mm) Minimum Distance Clearance from operable...
Site Selection and Preparation Install the generator outdoors in its protective enclosure where adequate cooling and ventilating air is always available. Also consider these other factors: • Installation must strictly comply with NFPA 37, NFPA 54, NFPA 58, and NFPA 70 standards. Install the generator where air inlet and outlet openings will not be obstructed by leaves, grass, snow, etc.
Site Selection and Preparation Figure 3-2. Southwest Research Institute Decal Southwest Research Institute Decal (located inside the generator, next to the generator’s data decal) http://www.swri.org/4org/d01/fire/listlab/listprod/director.htm Based on this testing and the requirements of NFPA 37, Sec 4.1.4, the guidelines for installation of the genera- tors listed above are changed to 18 inches (457 mm) from any point of the generator enclosure to a stationary wall, building or structure.
Site Selection and Preparation 3.2.1— Material Sufficient for Level Installation • Dig a rectangular area approximately 5 inches (127 mm) deep and about 6 inches (152 mm) longer and wider than the footprint of the generator. Fill with pea gravel, crushed stone or any other non-combustible material suf- ficient for level installation.
Generator Placement Section 4 4.1 — Generator With the Site Selection and Preparation performed, proceed with placement and installation of the generator itself. See Figure 4-1. All air-cooled generators come with a composite pad. The composite pad elevates the generator and helps prevent water from pooling around the bottom.
Generator Placement 4.2 — Fascia Skirt Installation (If Applicable) Install base fascia as follows: Remove four rubber mounts from Owner’s Manual bag. Screw two rubber mounts into threaded holes of end piece. See A of Figure 4-3. Snap end piece into side piece. See B of Figure 4-3. Fit rubber mounts in end piece into lifting holes at base of generator.
Fuel Conversion/Gas Connections Section 5 5.1 — Fuel Conversion Although the generator is configured at the factory for operating on natural gas, provision is made to switch over to LP Vapor. NOTE: The fuel selection (NG/LP) can be changed using the Installation Wizard at initial power up, or by accessing the EDIT Menu thereafter.
Fuel Conversion/Gas Connections NOTE: All pipe sizing, construction and layout must comply with NFPA 54 for natural gas applications and NFPA 58 for liquid propane applications. Once the generator is installed, verify that the fuel pressure NEVER drops below its required fuel pressure rating. For more information regarding NFPA requirements, refer to www.nfpa.org.
Fuel Conversion/Gas Connections When measuring pipe length, add 2.5 feet (0.76m) for each angle or bend in the pipe run and add that to the overall pipe distance. 5.4.1— Natural Gas Pipe Sizing The following table indicates the maximum length (measured in feet / meters) allowed for various pipe sizes. The pipe sizes are measured by inside diameter (ID) to include any fittings, valves (must be full flow), elbows, tees or angles.
Fuel Conversion/Gas Connections 5.4.3— Gas Installation Summary Mistakes frequently occur when sizing gas pipe. A properly sized gas pipe is critical to the proper operation of the gen- erator. The generator inlet size has no bearing on the proper gas pipe size. If using a piping method other than black pipe, refer to local codes and the pipe manufacturer’s specifications for sizing and installation information.

Fuel Conversion/Gas Connections Sediment Trap Figure 5-3. Sediment Trap Figure 5-4. Incorrect Routing of Flexible Hose When connecting the gas line to the generator, use the provided section of UL Listed or AGA-approved flexible fuel line in accordance with local regulations. The flexible fuel line ensures that vibration from the generator does not cause a gas leak at one of the connection points.

Operation Section 7 7.1 — Control Pad The control pad is intended for use by qualified service personnel only. See Figure 7-1. The control pad is located under the lid of the enclosure. The lid is secured by two locks, one on each side of the enclosure.
Operation With the control pad set to AUTO, the engine may crank and start at any time without warning. To prevent possible injury that might occur during sudden starts, always set the control pad to OFF and remove the 7.5 amp fuse before working on or around the generator or the electri- cal loads that are to be powered by the generator.
Operation 7.3 — Menu Navigation Feature Description System Menus The system returns to the Home screen if the control pad is not used for five minutes. The screen normally displays a Status message, such as Ready to Run (Auto mode) or Switched to OFF (Off mode), and the total Hours of Protection.
Operation 7.7 — Before Initial Start-Up NOTE: This unit has been run and tested at the factory prior to shipment and does not require any break-in. Operating the engine with the oil level below the ADD mark on the dipstick can cause engine damage.

Operation 7.7.2— Before Starting Complete the following: Verify that the generator is OFF. A red LED illuminates to confirm that system is in OFF mode. Move the Generator Disconnect Circuit Breaker switch to the OFF (Open) position. Turn off all circuit breakers/electrical loads that are to be powered by the generator. Check engine oil level.
Operation Close the disconnect switch if the appropriate voltage and frequency are present. Check voltage and frequency at the Alternative Power Management System by closing the breakers one at a time (if applicable). Allow the generator to run under load for 20-30 minutes while checking for unusual noises, vibration or other indi- cations of abnormal operation, such as oil leaks or overheating.
