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.
We recommend that the installation should be undertaken by Glazing Vision Engineers or Approved Installers (installers that have
attended a Glazing Vision Installation training course for this product and carry ‘Approved Installer’ status). This will ensure a reliable
product and enable the property owner to benefit from the full 10 year warranty on the product. It should be noted that an
installation by non-approved installers will result in a reduced warranty period of just 2 years. This is a safety critical product and if
installed by non-approved installers it must be commissioned by Glazing Vision personnel or Approved Installers.
By following the correct installation procedure, a reliable and high performing end result is guaranteed. The critical operations that
can lead to problems if not done correctly are the lifting, preparation of the upstand, and ensuring that the product is mounted on
the correct pitch with the hinge on the high side. Taking the time to carry out these operations correctly will ensure that the product
does not twist or distort and allow the installed product to move freely and unimpeded with minimum load on the mechanisms and
no undue stresses in the frame or glass.
Installation must only be carried out by suitably qualified personnel. Care should be taken when working on the product, avoiding
accidental damage and ensuring operational reliability. The mechanisms are very powerful, at no time should hands or arms work
through the mechanisms, always work around them.
Should you have any queries beyond this manual please do not hesitate to contact Glazing Vision.

Pre-Installation Preparation
These products can be very heavy. Due consideration should be given to getting the product onto the roof safely
and extreme care taken during installation.
Points to Note Prior to Commencing Installation
1. The Xvent should arrive on site in undamaged packaging, which includes a wooden build frame, cardboard, polyfoam glass
protection and low tack tape. Please inspect for damage to packaging and/or product and advise Glazing Vision of any
damage or shortfall within 48 hours from signing the receipt of your delivery.
2. Enclosed within the box containing this manual will be the required number of fixing woodscrews and a number of plastic
packers, as well as some silicone and other required materials. The installation kit is supplied with two switches (a control
switch and an isolator switch), a Power Supply Unit (PSU) and any additional optional items selected at the time of order.
Standard Installation Hardware
Enclosed within the hardware box for each unit you should find at least the following:
Stainless steel woodscrews
Plastic horseshoe packers
(various sizes)
Low modulus silicone
3. Xvents have three coiled cables emerging from the motor housing as standard (if optional extras have been selected, other
cables may also be present). This includes 2 single cores (red and black) 24V DC power cables, a 4 core fire panel connection
cable and a 6 core control cable. These cables will have red identification labels on them (labels should not be removed
until final installation). Please refer to Glazing Vision’s wiring diagrams for details of wiring requirements. Only the supplied
PSU can be fitted to the unit, failure to connect this unit or wiring direct to the mains will invalidate the product warranty.
4. The switch used to control the operation of the Xvent is a two button wall mounted control switch. This switch will allow
you to operate and stop at any position between the fully open and closed positions. This switch also contains a tri-colour
LED to display the product status to the user. The correct control switch is supplied in the installation kit and must be
installed to avoid invalidating the warranty. If required, this switch can be installed in a maintenance area and another
switch of a retractive single pole double throw (SPDT, ‘on-off-on’, latching off) type can be parallel wired for regular use.
Using a SPDT switch that only latches ‘on-on’ can seize the control board and therefore should not be used.
5. The Xvent also requires a 3A fused double pole single throw (DPST) type switch (not supplied). Combined with
disconnecting the batteries, installing this switch as per the wiring diagram will allow the control board to be reset in the
event of a fault (for more information on faults and troubleshooting see the operation and maintenance manual).
6. The upstand must already be in place for the product. The dimensioning of the product will have taken into consideration
the external dimensions of the upstand including all weathering. More information about upstand construction can be
found in Glazing Vision’s sales drawings. Please note that a minimum distance of 200 mm clearance between the upstand
and any surrounding structures must be left on all sides. Additional space to allow the lid to open to 140° (fire position)
must also be allowed for. This is to allow sufficient room for installation and maintenance.
7. It is important to ensure that the area of installation is suitably prepared. The area surrounding the upstand should be clear
to provide safe access during the installation works. It will be necessary to work on the outside and therefore suitable
provisions should be made for safe handling of the product, including all relevant personal protective equipment (PPE)
and safety systems for working at heights.

8. Before starting installation, Glazing Vision advises that the physical upstand dimensions are cross-checked with those given
for the order, to ensure the product will fit. The upstand will need to be within ± 10 mm of the ordered size. The top surface
of the upstand should be flat without undulations greater than ± 2 mm. Check that the cable exit hole has been included
in the upstand (refer to Glazing Vision’s sales drawings for the location). Also check the diagonals to ensure that the upstand
has been constructed square. The upstand must be weathered as per the sales drawings. If using any metallic
waterproofing material, this cannot be applied across the top surface of the upstand as this will cause a thermal bridge
which can lead to internal condensation and invalidate the product warranty.
9. These products can be very heavy. Glazing Vision strongly recommends that a structural engineer is consulted when
designing the structure(s) that will support the product and the surrounding structure. Nothing in this manual or on Glazing
Vision’s sales drawings constitutes a structural proposal.
10. Glazing Vision strongly recommends that a ‘dry run’ (without any silicone) is completed before committing to the final
installation.
Sales Drawings
Sales drawings for the Xvent can be obtained by downloading them from Glazing Vision’s website
(www.glazingvision.co.uk/resources) or by contacting Glazing Vision.

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.
Figure 1 –Upstand top trim placement
The upstand top trim should be cut to size along its length to leave a dimension of 190 mm between the edge of the cover and
outside of the upstand. This dimension ensures that the upstand top is covered and there is no contact between the upstand top
trim and the exterior product framework (which would create a thermal bridge). The upstand top trim is supplied with 5 grooves
along the underside. These grooves can be used to help guide a saw or similar when trimming the cover to size.
Figure 2 –Upstand top trim measurements
After all upstand top trim lengths have been cut to size and adjusted to fit, they can be fixed into place with the supplied fixings. Drill
holes at approximately 500 mm centres using the groove to aid with positioning of the drill bit. The upstand top trim has been
designed to accept standard 12 mm plasterboard to ensure a flush finish. Refer to the sales drawings for more information.

Fitting the Lifting Equipment
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.
To fit the lifting frame, it may be necessary to peel back and remove some of the protective packaging. Leave as much as possible
intact.
To assemble the lifting frame, start by mounting a lifting bracket to each corner of the base frame. Tighten the rubber feet to make
light contact with the top of the glass. Do not over tighten, the bracket only needs to locate so that it does not fall off but does not
need to be clamped on. Lastly, mount a lifting eye bracket to each of the lifting brackets and slide in the spreader bars to create the
full lifting frame. Everything should then be pinned in position through the closest holes using the clevis pins and the R-clips. Ensure
that all of the adjustment fixings are tightened appropriately for lifting.

Installation Procedure
Step 1
Remove all packaging from the product including polyfoam glass protection and low tack tape.
When removing the packaging, try to keep it intact as much as possible, so that after installation it can be re-used to
protect the product until project completion and final handover.
Gently prise all of the upstand fixing clip on covers off the framework drip legs.
Figure 6 - Clip on cover
Step 2
Apply two large lines of silicone (supplied in the installation kit) to the top of the upstand. The two lines of silicone need to be
approximately 50 mm and 150 mm in from the outside face of the upstand.
Figure 7 –Silicone placement
Step 3
Check that the lifting equipment is securely fitted to the unit.
Carefully lift the product to the installation site (roof) using strops underneath the wooden build frame. This is to ensure that the
build frame does not separate from the product during the lift. Do not lift the product to the roof using the lifting frame (this is for
installation purposes only).
Step 4
When on the roof the product should be lifted off the wooden build frame (remove the fixings first) and placed onto the upstand. To
do this, attach hooks to the shackle points on the lifting frame and then gently lower the product onto the upstand ensuring that
the cables are not kinked or snagged under the framework –feed the cables exiting from the underside of the unit into the cable exit
hole in the upstand.
