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.
If you are going to operate on LP, you will need to move
the fuel line from the NG port to the LP port on the fuel
outlet tee. These two ports have different orifice inserts
installed on them, which provide proper operation with no
further adjustments.
NOTE: When moving the
fuel line from one port to
the other, be sure not to
kink or bend the line. Use
a large sweeping curve as
possible and never shorten
the fuel line. For proper
operation, the fuel line
must stay the same length as it was shipped.
