Adjustments
13.1 If adjustment is needed, you will find a toe and heel device in the top of each door
13.2 Open the doors so that you can get access to the toe and heel device at the top of the door. Using a 4mm Allen key, wind the bolt clockwise, causing the side of the door to rise
13.3 Re-close the doors and check that they run parallel and evenly to the top and bottom tracks
13.4 Once you have adjusted the doors, make sure that each toe and heel plate is tight to the glass in each door, this will prevent the doors from settling over time
14.1 Check the top and bottom tracks are parallel, open all the door leaves completely
14.2 At this point, the pins in the centre of the top guide wheel should be fairly flush with the visible face of the guide wheel (FIG 14A)
14.3 Move the doors along the track whilst monitoring the pins in the top guide wheels. If the top and bottom tracks are parallel, the visible pin should remain the same as at the start
14.4 If the visible pin decreases at any point, the top track will need repacking to raise it up at these points, or check the bottom track is not bowed
14.5 If the visible pin increases at any point, the top track will need repacking to lower it at these points
14.6 Trim and reinstall the track gasket once adjustment is complete or check the bottom track is not bowing
NOTE: The bottom track must be well supported and level for the description above to be correct.
14.7 When the lead door is closed, there should be a visible gap of 4mm between itself and the jamb or locking style, adjust as follows if necessary*
14.8 Remove the two centre and top fixings and the top from one jamb - should be done after side jambs have been adjusted
14.9 Repack the top of the jamb to give a 4mm gap between the edge of the lead door and jamb both inside and outside
14.10 Replace the fixing in the top of the jamb and remove the bottom fixing from the jamb
14.11 Repack the bottom of the jamb to give a 4mm gap between the edge of the lead door and jamb
14.12 Replace the fixing in the bottom of the jamb, then pack and replace the remaining two fixings, keeping the even 4mm gap - ensure that the jambs are not twisted and have a continuous 4mm gap both inside and outside
*This is temperature dependent. When installing in particularly hot weather, the gap along the slam and rebate may need reducing slightly. In particularly cold weather, this gap may require increasing slightly. This accounts for the minimal potential expansion and contraction with the aluminium profile.
