8. IN CHANNEL SURFACE INSTALLATION
Always apply an anti-seize on the stainless
steel fasteners.
1- Frames are usually shipped unassembled.
The first step is to place the bottom section of
the frame (sill).
2- Start by precisely measuring and marking the
exact center of the sill.
3- Place the sill on the channel floor, making sure
to align the center to the center of the channel
that was previously marked on the concrete.
(Figure 6)
4- Level the sill with a calibrated 24” or 48” spirit level. Use
stainless steel shims to adjust the level as needed. For
frames having a free opening width exceeding 1500mm (60”)
use a calibrated laser level.
5- Mark and drill the 2 anchor holes of the sill at the extremities
(closest to the side wall of the channel). Install these 4
anchors.
6- Bolt the 2 frame sides to the sill and tighten the bolts firmly.
The 2 frame sides may comprise more than one section.
Sections can be bolted together and the bolts firmly tightened.
7- Place a plumb line on both side of the channel near the frame
sides. Check and adjust verticality of the frame sides in both
axes along the whole channel depth. Tolerance on verticality
is ± 3mm (1/8’’) on the channel depth. Maintain the frame
sides in position using the crane or other method depending
on the available tools. (Figure 6)
8- Make sure to maintain a minimum gap of 16mm (5/8")
between all parts of the frame and the sidewalls to allow
enough clearance to pour the grout. If needed, reposition the
gate while maintaining the sill level and verticality of the
sides.
9- Mark and drill the remaining anchor holes on the bottom frame (sill). Install and tigthen the anchors
(see figure 6)
Apply anti-seize on each anchor rods.
10- Check straightness of the bottom frame (sill) using a straight-edge or a tight string from one corner to
the other. A maximum variation of 2mm or less is acceptable. Correct if needed by tightening the
intermediate anchor(s) and/or adding shims.
11- Drill the 2 anchor holes, on each side of the frame, closest to the top of the door. Install the anchors.
