Self-closing door
The stove is equipped with a spring to close the door
automatically. The spring is situated above the heat deflector.
The closing force of the hatch can be adjusted by moving the
spring between the three notches on the lever. The angle of the
stove also affects the closing force of the spring.
If the spring force seems weak, despite the spring being
mounted at the end of the lever, the angle of the stove
should be checked. Adjust with adjustable feet if necessary.
