Quick Answer
When a kerosene heater runs out of fuel, it will stop producing heat and may continue to draw air, causing a buildup of carbon monoxide if ventilation is inadequate.
What Happens Internally
When a kerosene heater runs out of fuel, the burner will shut off, and the heater will enter a standby mode. However, if the heater is not properly shut down or if the fuel line is not depressurized, the heater may still attempt to draw air, potentially leading to a buildup of carbon monoxide. This can be extremely hazardous to occupants in the space.
Safety Precautions
To mitigate this risk, it’s essential to follow proper shutdown procedures when refueling or replacing the heater. This typically involves turning off the heater at the power source, allowing it to cool, and then opening the fuel line to release any residual pressure. Additionally, ensure the heater is installed and maintained according to manufacturer guidelines, and always follow the manufacturer’s instructions for shutdown and refueling procedures.
Ventilation and Maintenance
Proper ventilation is critical when operating a kerosene heater. Ensure the space is well-ventilated to prevent the buildup of carbon monoxide. Regular maintenance, such as cleaning the heater’s air intake and fuel line, can also help prevent issues. It’s also recommended to have a carbon monoxide detector installed in the space to alert occupants to potential hazards.
