INSTALLATION OF WELDED FRAMES
PRIOR TO INSTALLATION
The installer shall perform the following prior
to installation:
The area of floor on which the frame is to
be installed and the path of the door swing
shall be checked for flatness and levelness.
Permissible tol-erance is +/- 1/16 in. (1.5mm). If
the floor exceeds this, it is the general
contractor’s responsibility to correct the area
that is out of tolerance before the frame is
installed.
Frame shall be checked for correct size, swing,
fire rating and opening number.
Remove temporary steel spreaders. Spreaders
can typically be removed with cold chisel and
hammer. With frame standing on concrete,
position cold chisel at weld joint of spreader
and jamb and strike chisel with hammer.
TYPICAL INSTALLATION PROCEDURES
Position frame in the correct location. Brace
the
frame as shown, Figure 1. Do not brace in the
direc-tion of intended wall.
FIGURE 1
FRAME BRACING
With frame in position, install the temporary
wood spreaders. The wood spreader, Figure 2,
m
ust be square and no less than 1 in. (25 mm)
thick. Correct length is the door opening width
between the jambs at the header. Cut
clearance notches for frame stops. Spreader
must be nearly as wide as frame depth for
proper installation. Install a spreader at the
bottom of the frame and a second wood
spread-er at the mid or strike point to maintain
a proper door opening and to prevent bowing
of the jambs, Figure 3. Clamp or wire spreaders
to frame to hold spreaders in place until the
frames are set perma-nently in the wall.
