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.
