Remember that whichever fuel delivery system or type of
vapor fuel used, the fuel pressure at the demand regulator
installed on the engine generator must be between 4 and
6 oz (7-11 inches of water column). Any lower pressure and
the unit will starve for fuel under load. Any higher and the
unit will ‘flood’ when attempting to start.
CHANGING FUEL TYPES
These engine-generator sets are designed to run on two
different fuels; gasoline and natural gas. They may be easily
changed from one fuel to another.
GASOLINE TO NG
1. With the engine running, turn off the gasoline valve.
2. Run the engine until it runs out of fuel.
3. Remove the plastic insert from the demand regulator.
4. Install a locally approved flexible fuel line.
5. Connect the NG fuel line to the flexible fuel line. You
can’t connect the ridged mounted pipe directly.
6. Turn on the vapor fuel.
7. Start the engine.
8. Apply the load to the generator.
NG TO GASOLINE
1. With the engine running turn off the NG fuel supply.
2. Run the engine until it runs out of fuel.
3. Remove the flexible fuel line from the demand
regulator.
4. Reinstall the plastic insert in the regulator.
5. Check to be sure the gasoline fuel valve is off.
6. Fill the gasoline fuel tank.
7. Turn on the gasoline fuel valve.
8. Start the engine.
If the optional Fuel Solenoid kit has been installed on the
unit, all vapor fuel connection will be made at the 12 Volt
gas valve.
OPTIONAL DOLLY KIT
An optional dolly kit is available for this generator. The dolly
kit comes with instructions and a parts list. After installing
the dolly kit, file the instructions and parts list in the back of
this manual for future reference.
OPTIONAL FUEL SOLENOID KIT
An optional 12 Volt DC fuel solenoid kit is available for
this generator. This solenoid kit will automatically shut off
the fuel supply should the engine stop for any reason,
preventing fuel leaks. This kit is recommended if you are
going to be operating the generator unattended.
