NG/LP FUEL CONVERSION
These generator sets are factory tested on NG and will
require no modifications for normal operation on NG. The
carburetion system has been preset and anti-tamper plugs
have been installed in the carburetor as required by the
EPA.
To make a fuel conversion you will have to first remove
the left side door. Looking down and to your left, you
will see decal and a plug. Remove the plastic plug with a
screwdriver. Using a 5mm or 3/16” hex allen wrench, turn
LEFT about 1/4 turn until you feel a click and it will stop
turning.
No other modifications to the unit are necessary. To switch
from LP to NG, you turn the selector to the right (NG)
position.
