When using this product and the heat insulating double chimney penetrates the wall or floor, the use of the adjuster pipe (slide chimney) is prohibited because it is dangerous.
If the adjuster pipe (slide chimney) is extended, a double chimney part that is not filled with insulation will be created.
If an air-insulated chimney that is not filled with insulation penetrates the wall, the risk of fire is extremely high and dangerous.
