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.

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.
Scorching of the internal fabric may occur at 150°C. Neither of
these reactions will impair the performance.
