Silicone resistance up to approximately 280 degrees Celsius Compatible chimney diameter: 4.5-10cm (for chimneys over 4.5cm, trimming of the apron may be required) Installation Instructions: (1) Locate the chimney opening on the tent: a. Determine the position of the chimney outlet on the tent. b. Use the circular steel plate to mark the screw hole positions and cut accordingly. (2) Cut two pieces of abrasion-resistant material to match the shape of the circular steel plate (included with the silicone sleeve). Thick fabric can be used as an alternative. Note: This step is optional. Adding abrasion-resistant material helps protect the tent from wear. (3) Place the cut abrasion-resistant material and steel plate inside the tent opening. Align the screw holes and insert screws from the inside to the outside. (4) On the outside, place the abrasion-resistant material, silicone sleeve, and steel plate in sequence. Secure with nuts and tighten screws. (5) Trim the tent fabric inside the silicone ring to complete the opening. (6) Insert the chimney pipe and use. For chimneys with a 4.5cm diameter, minor trimming of the silicone ring may be necessary.
