Check Your Gauges

This post applies to all EnergyLogic Waste Oil Heaters and Boilers –

Here at NuEra, we are always happy to offer free phone-support for troubleshooting your EnergyLogic Waste Oil Heater or EnergyLogic Waste Oil Boiler. As the new guy, there was a learning curve for me in doing so. It’s one thing for me to look at a Waste Oil Burner and dive into it to fix whatever the problem may be, and an entirely different thing to use YOUR eyes and ears to do the same. In the interest of reducing the amount of down-time for your EnergyLogic Waste Oil Burner, I thought I would offer a few tips for troubleshooting.

The EnergyLogic Pressure Gauge (PN 20270183), and EnergyLogic Vacuum  gauge (PN 20270188), found on your metering pump assembly itself, are your first stop for information on how the Waste Oil Burner is operating.

Troubleshooting– First, be sure that the ball valve on the inlet side of your Preheater Assembly is in the open position.

• Monitor the gauges when you start the machine. If your EnergyLogic Burner doesn’t light immediately, you have between 15 and 30 seconds to read the gauges before thermal lockout.


• Pressure Gauge-Should read 6-9 PSI range. Up to 15 PSI is not unusual, but over that and you most likely have some sort of restriction in your fuel line, preheater, solenoid, or nozzle assembly.

If your gauge readings are in the acceptable range, but the machine won’t light, go on to verify that Waste Oil is reaching the inlet and outlet of the Solenoid Valve, as well as the inlet for the Nozzle Block Assembly while the Waste Oil Burner is trying to light.

Basic (burnable!!) fuel delivery is the number one cause for ill-behaving machines, and this simple check can save you both time and money.
