Cause: No kerosene. Troubleshooting: Add fuel to the tank and light it after half an hour. Cause: Water in the fuel tank Troubleshooting: Empty the tank of water and replace the wick.

Cause: The wick is too high. Troubleshooting: Lower the wick. Cause: The burner/chimney is not seated properly. Troubleshooting: Adjust the chimney. If the problem persists, remove and clean the chimney.

Cause: The wick was installed too high. Troubleshooting: Reinstall the wick and place it lower. Cause: Burnt carbon residue accumulated on top of the wick. Troubleshooting: Extinguish the flame with a wet blanket. Once cooled, remove the chimney and clear the wick residue using a tool like pliers, then dry-burn it.

Cause: The heater is in a closed/unventilated space. Troubleshooting: Open windows for airflow. Cause: The bottom of the chimney is not seated correctly on the burner bed. Troubleshooting: Move and adjust the chimney until it is properly seated. Cause: The wick is too high or too low. Troubleshooting: Adjust the wick. If the top of the wick is torn, replace it.

Cause: The top of the wick is carbonized/clogged. The wick is coated due to low-quality fuel or swollen due to water absorption. Troubleshooting: Burn the heater without kerosene (dry burn) to detach the burnt parts. Clean the wick adjuster and the main air pipe, then fill the tank with high-quality kerosene.

Cause: Indicates the presence of water in the tank and the wick. Troubleshooting: Empty the tank, clean it, dry it with a paper towel, and then fill it with fresh, high-quality kerosene. Replace the wick and reassemble the heater.

Cause: The wick is contaminated. Troubleshooting: Dry-burn or replace the wick. Cause: The kerosene is too cold. Troubleshooting: Wait until the kerosene warms up.

Cause: The igniter (lighter) is defective. Troubleshooting: Replace the igniter. Cause: The battery is dead. Troubleshooting: Replace the battery. Cause: The wick is contaminated. Troubleshooting: Dry-burn the wick.

Cause: Odor during operation may be due to impurities in the kerosene, a very dirty wick, or kerosene spilling onto the wick adjuster, auxiliary fuel tank, drip tray, etc. Troubleshooting: Clean the heater and dry-burn it to clean the wick. If the odor persists, replace the fuel with high-quality kerosene. If you feel a burning sensation in your throat, nose, or eyes, it is highly recommended to replace the kerosene with good quality fuel immediately.

Cause: Carbon deposits on the wick. Troubleshooting: Rinse the tank and fill it with good fuel - dry burn - refill with good fuel, and carefully clean the wick adjuster and main air pipe. Cause: Water repels fuel flow even in clean, carbon-free wicks. Troubleshooting: If you suspect water, empty and dry the tank, then clean it and fill it with fresh, uncontaminated fuel. Cause: Fuel is too heavy or too cold. Troubleshooting: Heavy or oily kerosene moves through the wick and evaporates slower than lighter kerosene. Kerosene at low temperatures evaporates much slower. If you encounter a "low flame" problem, let the unit warm up for a long time. It takes a long time for cold fuel to fully penetrate the wick.

Cause: High, unstable flame and smoking are caused by improper positioning of the heat chamber, incorrect placement/sealing of the wick adjuster inside the tank, or exposing the heater to strong drafts. Troubleshooting: Check the heat chamber positioning. Inspect the wick adjuster placement inside the tank and tighten it with a screwdriver if possible. Move the heater away from drafts. Note: In some cases, if the fuel is highly volatile, a high unstable flame (which may flicker) occurs after 1-2 hours of operation. If this happens, carefully turn off the heater and let it cool. Drain the fuel, rinse the tank, and refill with fresh, high-quality kerosene.
