Troubleshooting
If you are having problem with this unit, refer to these troubleshooting hints.
The generator not light
1) There could be air in the gas line, especially when changing propane tanks or turning on your generator for
the first time. Turn generator off and turn it back on. Let it attempt to light 5 times and then repeat.
2) If the generator lights the main burner and then immediately turns back off, the flame sensor may not be
directly in line of the flame. Tighten up the slotted jet caps on both sides of the spark ignitor/flame sensor so
that the flames coming out of the burner are aimed at the spark ignitor/flame sensor. Bend the mounting
bracket slightly to adjust the flame sensor to be in the heat of the flame.
3) Make sure that tank is full and that the gas is turned on.
4) Verify the unit matches the type of gas you are supplying and the gas pressure is correct.
The flame on the main burner seem either too large with yellow flame or too small “flashing” ON and Off
1) You may have mixed burners. Verify you are using natural gas burner with natural gas and propane burner
with propane.
2) Lazy yellow flame indicate low gas flow due to low propane tank level or low natural gas pressure. Long
piping runs with natural gas need to be appropriately size.
3) Verify the unit matches the type of gas you are supplying and the gas pressure is correct.
The unit is plugged in and turned on but the burner don’t work
1) Verify the power switch is ON and the power supply is getting power.
2) make sure the unit is level. If the unit is title more than 35 degrees in any direction, the unit can’t operate.
NOTE: After making the gas connections ALWAYS check for leaks using soapy water and a spray bottle.
This unit is not for residential use. The exterior of the unit can get very HOT when in operation.
Always wait for generator to properly cool down prior to servicing or removing the front panel.
Do not operate the unit with the front panel removed.
When the unit stops using or depositing in the room, should turn off the power and gas source.
When it does not use for a long time, should separate the CO2 generator and gas source.
