Large Penetration Kit For Inner Diameter 125mm / Outer Diameter 175mm Steel Glasses Plate SUS304
This product is used when a double chimney penetrates a wall or floor.
One side has ventilation openings and one side has no ventilation openings.
When penetrating the wall, there is a ventilation opening on the wall surface on the indoor side, and it is used without a ventilation opening on the outer wall surface.
By doing this, it has the effect of discharging the heat that stays in the wall, so it is highly safe.
In Europe and the United States, there is a rule that when an insulated double chimney passes through a wall or floor, it must be constructed at least 5 centimeters away from combustible materials.

By using this wall and floor penetration kit when penetrating walls and floors, it is possible to keep a minimum distance of 5 cm or more from combustible materials.
The material is made of SUS304, 2 mm thick and heat-resistant to 300 degrees.
The outer dimensions are 475 mm x 475 mm, and there is a hole (approximately 185 mm) through which a chimney with a diameter of 175 mm can easily pass.
When using this product and the heat insulating double chimney penetrates the wall or floor, the adjuster pipe (slide chimney) is dangerous, so please observe the following when using it.
If you extend the adjuster tube (slide chimney) and use it, you will end up with a double chimney that is not filled with insulation.
If an air-insulated chimney that is not filled with insulation penetrates the wall, the risk of fire increases and is dangerous.
If you want to stretch it out in the penetrating kit part, please purchase a ceramic fiber blanket that is sold separately and pack it in.
