Q.What is the structure of double wall tank?

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.
The pipe is a thin with an inner diameter of 4 mm and a length of 30 mm and is located at the rear of the unit (opposite the fuel gauge and the fuel inlet cover when they are in front of the unit)

【Notes】

The following symptoms may occur if the dust stacks the pipe.

①Fueling from the fueling port and the fire is extinguished halfway through even though there is enough remaining in the fuel gauge. After a certain period of time has elapsed, ignition is possible and the same symptoms are repeated.

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