  If the Heylo Heater burner starts but shows interference with the red lamp lit, the issue could stem from several causes: * The oil tank may be empty, in which case you should refill it. * The oil pipe might not be connected, or the main tap could be closed; inspect the pipeline and main tap. * A dirty oil filter can cause this issue, so clean the nozzle filter, pump filter, and pre-filter. If needed, change the nozzle. * The oil suctioning pipe may not be sealed properly, causing the pump to suck in air. Ensure the oil suctioning pipe is sealed and that the oil in the reverse flow pipe is free of bubbles. * Lastly, the oil pump might not be producing enough pressure. In this case, set the pressure correctly.

  If the flame of your Heylo Heater goes out after starting or burns intermittently, consider these potential causes and solutions: * A dirty photo conductive cell could be the culprit. Pull it out and wipe it with a clean cloth, especially if the room is dusty. * Dirty oil filters can also cause this issue. Check and clean all oil filters, including pre-filters, pump filters, and nozzle filters. * If the oil suctioning pipe isn't sealed properly and the pump is sucking in air, seal off the oil suctioning pipe and tighten all screws. Ensure the oil in the reverse flow pipe is free of bubbles. * A blocked burner nozzle could be the problem. Replace it with a new one instead of attempting to clean it. * Combustion air might not be properly set.

  If your Heylo Heater's room thermostat switches off the burner prematurely, it might be because the thermostat is placed where it's exposed to hot air or heat sources like sunlight, machinery, or hot water/steam pipes. Try moving the thermostat to a different location.

  If the burner isn't running, here's what you can check: * Ensure there's a power supply using a voltage tester or lamp. Turn on the main switch, replace the fuse, and inspect the supply line for loose connections. * If using a room thermostat, make sure it's set above the current room temperature. * If the automatic oil firing device indicates a malfunction, wait about a minute, then switch on the illuminated button to suppress interference. The disturbance indication and signal display should turn off, and the burner will attempt to restart. * If the safety temperature limiter has interrupted the power supply, identify and eliminate the cause of overheating, such as resistance to suction or blowing.
