To install the Round Finishing Plate, begin by marking the precise location where the flue penetrates the non-combustible wall. Clean the surface thoroughly before applying a high-quality silicone sealant. Secure the plate onto the wall using appropriate screws. Ensure that the locking band is firmly in place to uphold a clearance of 50mm (TWPro) or 60mm (KC) from combustible materials. Always adhere to the product manual guidelines and consult a professional installer if you are unsure about any step.

The outer skin of the plate is made from 304 grade stainless steel, while the inner skin is made from 316 grade stainless steel. Both are 0.4mm thick and insulated with compressed rockwool for optimal thermal performance.

Secure the plate to the wall where the flue passes through at 90° using silicone and screws. Ensure the locking band is used for a secure fit.

Maintain a distance of 50mm to combustibles with TWPro and 60mm with KC from the outside of the flue.
