FAQ / Wick Type Kerosene Heater

A.The fuel tank has double wall. Even if the heater fells over, the structure is designed to prevent kerosene from spilling.

The kerosene fueled from the port is supplied from outside of the tank through the pipe into inside of the tank.

②The flame becomes smaller and smaller about 10 minutes after ignition, even though the new wick has been replaced.
