Installation Once the flanges have been installed, the insulation jacket can be fitted as follows: IJ
Place the jacket onto the pair of flanges, wrap around and secure jacket into position by using the velcro flap. The label should be facing the installer and the large flap on the underside of the flanges to prevent the ingress of water. Finally, pull and tie the drawcords to minimise any gaps that would allow air to flow through or allow ingress of water. IJ-H Place the jacket onto the pair of flanges, wrap around and secure jacket into position by using buckle straps. The label should be facing the installer and the large flap on the underside of the flanges to prevent the ingress of water. Finally, pull and tie the drawcords to minimse any gaps that would allow air to flow through or allow ingress of water. Important note: Both the inner/outer face and insulation are made with a bonded aluminium foil. At a temperature of 120°C the adhesive bonding the aluminium will start to degrade and delamination of the foil will occur at 150°C to 170°C. Scorching of the internal fabric may occur at 150°C. Neither of these reactions will impair the performance. Removal Before removing the jacket, check if the flanges are in service. If they are then the metal surface will be hot enough to burn and suitable protective clothing (e.g. gloves) should be worn. Removal is the reverse procedure to the above. Handling When the jacket is new the insulation material is fully enclosed within the inner and outer face and retained by the stitching. In this condition for handling no special protective clothing is required. However, if the inner and outer face becomes unstitched or damaged, so as to expose the insulation material then suitable protective clothing (e.g. gloves, safety glasses, face mask and overalls) should be worn when handling. Disposal This product is not recyclable and is non-combustible. For disposal purposes consider the product to be mineral fibre and dispose of in accordance with local regulations.
