Introduction Thank you for purchasing a Glazing Vision Xvent. In order to ensure that it gives you many years of service it is important that before commencing any work you read these instructions fully and ensure that they are strictly followed for a successful and trouble free installation.
These products can be very heavy. Extreme care must be taken during handling and installation. Full consideration should be given to how you will safely transport your rooflight product from the delivery vehicle to the installation location. Glazing Vision strongly recommends that specialist, mechanical lifting equipment is employed.

405-INST-UK-001 v1.0 – 09 Jul 2020 Upstand Top Trim Installation Begin by cutting the upstand top trim to the lengths required for all sides of the upstand. The corner joints can either be mitred (45°) or straight cut with notches (see image below). If the material requires bending to suit the pitch of the upstand, this can be achieved by screwing the section to the upstand as below and gently tapping the horizontal part using a clean rubber mallet.
The lifting frame is usually (but not always) attached to the product prior to dispatch. Once the product is installed, please return the lifting equipment to Glazing Vision. The lifting frame is fully configurable and will fit any size of product. Use Glazing Vision’s drawing of the lifting frame to assist with identifying parts and how they fit together.
405-INST-UK-001 v1.0 – 09 Jul 2020 Installation Procedure Step 1 Remove all packaging from the product including polyfoam glass protection and low tack tape.

Voltage adjustment is via a screw potentiometer accessed through the front cover (remove small plastic plug first). The PSU is external to the Xvent and can be mounted some way from the product, possibly resulting in a slight volt drop. This is a common reason for a slightly lower voltage at the battery terminals and requires adjusting.
Glazing Vision does not specify the finishes permitted except for the following stipulations: • The finish must be built up to the internal dimension of the product – see Glazing Vision’s sales drawings. • No interior metal component (for example edging strips for plastering) may touch any part of the product framework that is the outer colour (RAL 7015 grey as standard).
