B. Natural Gas (NG)
If the engine is set at the factory to run on natural gas, please check
the fuel pressure and flow. The purchase of a pressure reducing valve
might be required, and it is not included with this unit.
After installation please contact a service provider if user wants to switch fuel types from Natural Gas (NG) to
Liquid Propane Gas (LPG) or vice versa. Please contact the seller, installer or manufacturer at 844-367-5660.
4. Electrical Connections
If the generator set is used for standby power, install properly sized automatic transfer switch (ATS) provided
by manufacture. This will prevent inadvertent interruptions of standby power and normal sources of supply.
Always shut down generator before servicing the equipment. Never contact electrical leads or appliances
when standing in water or on wet ground because these conditions increase the risk of electrical shock.
5. Battery
Connect positive lead wire first (+) and then negative lead wire
(-) to matching positive (+) and negative (-) terminals on battery.
Connect negative (-) lead last!
IMPORTANT! The generator will not start, and circuit board damage can occur
(Before initial use the maintenance free battery should be tested for voltage, if >12.6V, it can be
installed and used immediately; After first time use or <12.6V it should be re-charge before use.)
For first time use, you should operate according to the steps below:
• Installing battery - take off red cap on positive battery terminal.
• Use a multi-meter to check voltage of battery before installing and starting. If reading is
below 12.6V, recharge battery.
• Connect positive terminal lead fully. Tighten terminal nut on battery lead and place red rubber
cover over terminal.
• Follow the same steps for negative or black battery lead, then place rubber cover over terminal.
