Begin by aligning the Wall Sleeve with the chimney flue ensuring a continuous fit through the wall. Fill any small gaps between the flue and sleeve using Rockwool for improved heat retention. If passing through a 45-degree angle, taper the Wall Sleeve carefully using a grinder or hacksaw to get a perfect match without compromising structural integrity. Secure the installation with the recommended Locking Band and maintain the necessary clearances from combustible materials (TWPro: 50mm, KC: 60mm). Always adhere to manufacturer guidelines and consult a professional installer if any uncertainty arises.
