Thank you for purchasing your Howells Glazing Roof Light System, which has beenprefabricated by our team of our skilled craftsmen prior to delivery.

The following instructions will ensure an efficient and easy installation of yourroof light . These instructions cover both delivery in flat-pack and assembled form

A little time spent looking through the instructions prior to commencement will help togive an understanding of the structure and the processes involved and will help to avoidcomplications during assembly

Tools Required

For your safety when installing yourroof light you should observethe following points:

• Always use relevant ‘Personal ProtectiveEquipment’ (i.e. gloves, helmet, goggles,safety shoes etc.) when erecting theconservatory.

• All power tools used outdoors should be 110 volt and connected through a transformer.

• Window frames supporting therooflight roof should be installedstrictly in accordance with the systemmanufacturer’s instructions.

• The use of a stable working platform(scaffold or trestles) is highlyrecommended for any conservatoryinstallation.

• Do not rely upon incomplete structures to support your weight (either directly or via ladders).

• Only use ‘Low Modulus, Neutral Cure’Silicone for sealing aluminium to brickwork,concrete or Lead

• Check tightness of all fixings prior toglazing roof or frames.

• Building sites (whether large or small) are dangerous places. As such, thegeneral public (particularly children)should be kept away until the installationis complete.

• Remove all debris from the site uponcompletion.

The main components of the Tiewire are the coil of wire and the bracket box.

Refer to the conservatory roof plan supplied to show the position of the Tiewire.

The bracket box will contain a pair of brackets, the tensioner and the dome nuts and washers for fixing the brackets to the rafters.The design of the brackets and tensioner may vary depending on the roof system.

The Synseal (Global) roof uses 2 security bolts (84mm apart).Ensure these are tightened with an Allen key.Note: it is usual practice for the roof fabrication company topre-fit the two bolts in each rafter. Please refer to the seperatebracket position drawing for drilling and fixing should the bolts be supplied loose.

Other roof systems use 4 bolts through the rafter drainage channel. Seal over the heads of the screws in the rafter drainage channel to reduce risk of leaks through the bolt holes.Note: it is usual practice for the roof fabrication company topre-drill the four bolt holes in each rafter. Please refer to the seperate bracket position drawing for drilling these holes should it not be done.

Uncoil the wire from the box, note the different terminal at each end. One end should have a locknut fitted.

Take the end without the locknut fitted and thread it into the pin through the slot in the bracket.

Ensure the thread on this terminal goes all the way through the pin.

Take bracket and attached wire to the rafter and fasten the bracket to the rafter bolts using the dome nuts and washers provided. Let wire hang down until you have fitted the opposing bracket.

Fasten the other bracket (the one with the threaded stud pre-fitted) onto the opposing rafter on the other side of the conservatory roof. Use the dome nuts and washers provided.

Take the tensioner and thread it onto the threaded stud 1 turn only (clockwise using end of tensionerwith red spot as shown in photo).

Take the other end of the wire (the one with the lock nut fitted) andbring it across the roof to meet the tensioner.

Insert the wire fitting into the tensioner and turn the tensioner clock-wise until the tensioner tightens equally onto both the wire fitting and the threaded stud.

Keep tightening the tensioner until the slack is removed from the wire.Use the spanner flats on the wire fitting (to stop the wire rotating) until the wire becomes taught and the window frames are plumb.

Pull down on the wire to relieve any ‘lock-up’ check the tension andtighten the two locknuts against the tensioner.

Each Tiewire is made to measure. Should the wire length appear too long or short, check the internal width of the conservatory and the length of the wire against the sizes shown on the label (back of box). The wire length is measured between the spanner flats on each fitting.
