Pre-installation - Lift, carry and store windows and doors in an upright position, under cover where possible to protect against damage. Do not rack frames out of square.

1. Ensure that prior to installation, flashing is fitted to sills and where required, to jambs and heads.
2. Install frames square with sashes closed - check diagonals for squareness. Brace or adjust braces where required. Ensure that frames are not twisted.
3. Correctly wedge all frame member joints without bowing, back nailing where possible. Provide secure fixing to meet site weather conditions. Note: special fixing systems are available for A.T. 2000 Series™ products. Refer to a Stegbar sales office for specific product fixing information.
4. Check that the sill is straight and level. If required, pack with Hardiflex or similar sheet to support front to rear.
5. Ensure that jambs are not bowed when bricks are being laid.
6. Allow 10mm clearance between window sill and external sill bricks on brick veneer construction.
7. Allow adequate head clearance according to span - minimum 20mm. Note: windows and doors are not load bearing. Refer to Stegbar installation instructions for external bi-fold doors.
8. In timber frame construction, recheck that sill and head are straight and level prior to fixing architraves.
9. Do not slide planks or tread on window frames. Protect door jambs and sill during construction.
10. After installation remove racking braces where fitted.
11. Protect all surfaces from brick cleaning acid, mortar, plaster, etc. Wash away any spillage immediately or permanent damage will result, thus voiding the warranty.
12. Highly concentrated brick cleaner will result in damage to paint work, and corrosion, including stainless steel fixings. This will result in black marks around the heads of brads, fixing glazing beads, and around the heads of screws in timber.
13. Timber sections exposed to the weather must be surface finished within 90 days to ensure warranty protection. Timber products supplied untreated including timber reveals on aluminium windows and doors, should be surface finished as soon as practical, within 35 days. Reveals on aluminium windows and doors must be primed prior to installation into cavity brick construction to prevent moisture absorption. Timber hung doors should be stored on edge, honeycomb doors stored flat, in a dry and protected area. When stored in excess of 30 days, seal all surfaces and edges beforehand.
14. Fixing through exposed timber should be, hot dip galvanised steel, 300 series stainless steel, or silicone bronze. Do not use uncoated steel fixings through timber or steel wool for dressing timber, or allow steel grinding particles from abrasive cut-off wheels to be deposited on any timber face. These will react with water on timber and produce black marks. Most black marks and other stains can be removed from timber by application of Intergrain "Reviva" timber cleaner (an Orica woodcare product). Follow manufacturers instructions for application. Where this is not successful contact a Stegbar sales office for further advice.
15. It is the builder's responsibility to ensure that windows and doors are installed to meet the wind loading and the human impact safety glazing requirements of AS1288. This particularly applies to windows installed within 300mm of a doorway and windows installed in a bathroom. If in doubt please consult a Stegbar sales office.
