FUEL SELECTION

NATURAL GAS (NG) SETTINGS

Units are tested with natural gas before they leave the factory. If natural gas is to be used, no adjustments are required. The fuel select switch, located on the bottom of the control panel, should be in the (NG) position. The (NG) position is with the switch depressed away from the front of the control panel (see A in illustration 1)

LIQUID PROPANE VAPOR (LPG) SETTINGS The fuel select switch position for liquid propane

vapor (LPG) is with the switch depressed toward the front of the control panel (see B in illustration 1).

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, arc-producing equipment, switches and all other sources of ignition well away. Keep a type ABC fire extinguisher handy.

•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.

Per the National Gas Code (NFPA 54 - ANSI 2223.1), a manual shutoff valve in the fuel supply line to the generator is recommended. 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.

CARBURETOR ADJUSTMENTS

The main adjustment screw is located on the side of the fuel mixer (as shown in illustration 2). Start unit at no load and verify proper operation. Loosen jam nut on adjusting screw. Slowly load unit to full load, adjusting load screw counter-clockwise as required to achieve maximum power. Once smooth full load operation is achieved, tighten adjustment screw jam nut, then return unit to no load to verify proper operation.

CAUTION

•This adjustment should only be performed by trained personnel. If incorrect adjustments are made, the unit may fail to operate or operate inefficiently.
