Converting from NatGas to LP
•The Guardian Series Air-cooled Generators are configured at the factory for NatGas.
•To switch over to LP, turn the orange fuel conversion knob towards the marked fuel source arrow until it
stops (clockwise).
• If needed, push in and use pliers to break free in the correct direction of the arrow.
• The fuel knob will rotate 180deg and slide into the mixer body when converting to LP.
•The generators are run at the factory with NatGas; sometimes the O rings seat themselves when the
Generator heats up.
• If the orange knob breaks off when you turn it with pliers, call us and we can get a replacement. (Generac
says they have fixed the problem.)
 The knob is located at the bottom of the fuel mixer for the single cylinder engines (as shown). It is
located on the top for the V-twin engines.
 Turn the valve 180 degrees in the direction of the arrow until it stops. Use pliers only if needed.
