  Poor combustion and excess soot production in your Pinnacle Heater can stem from several issues. Check the air or lint filter and clean or replace it if it's dirty. Similarly, a dirty fuel filter should be cleaned or replaced. The fuel quality itself might be the problem; try flushing the fuel tank and refilling with fresh, high-quality fuel. Ensure that the pressure is correct. Lastly, a dirty nozzle can cause this issue, so clean or replace it.

  If your Pinnacle Heater doesn't turn on and the lamp isn't lit, first, ensure the temperature limit sensor hasn't overheated. Turn the power switch to 'OFF,' let the heater cool for 10 minutes, and then restart it. Check that the power cord is properly connected and test the power supply. Also, inspect the fuse and replace it if it's blown.

  If your Pinnacle Heater won't operate and the LED display shows “E1”, start by checking if there is kerosene in the fuel tank and fill it with fresh kerosene if needed. Ensure the pump pressure is correct by adjusting it. Inspect the spark plug for corrosion or incorrect gap and clean or replace it. A dirty fuel filter or nozzle could also be the cause, so clean or replace them. If there's moisture in the fuel tank, rinse it with clean, fresh kerosene. Make sure the ignitor wire is connected to the spark plug and that the rotor spacing is correct. If the ignitor is defective, replace it.

  If your Pinnacle Heater ignites but the main PCB shuts off shortly after, displaying error code E1, there are several potential causes. It could be due to incorrect pump pressure, which requires adjustment. Another reason could be a dirty input, output, or lint filter, needing cleaning or replacement. A dirty fuel filter or nozzle can also cause this issue, so inspect and clean or replace them as necessary. Other potential causes include a dirty or improperly installed photocell or a defective photocell, which should be cleaned, adjusted, or replaced. Check wiring connections between the main PCB and the photocell, as well as the thermister placement (excluding the 45-KFA model). Finally, an improper electrical connection within the temperature limit switch may be the problem; consider rep...
