Secondary Installation
Note: The Adjustable Surround can only be installed onto the Colonial or Classic Surrounds, it is not
intended to be installed on its own with the Sonnet unit.
ASSEMBLY:
1. Line up the two (2) screw holes in the left hook bracket with the second slot in on the back of the left
trim side (refer to Figure 58). Center the bracket between the top and bottom of the trim (approximately
1⁄8” (2.5mm) from either end) and fasten the bracket in place using two (2) #8 screws.
2. Install the right hook bracket onto the right trim side using the same method used in Step 1.
3. Only if installing Adjustable Surround: Slide one mounting bracket back into the inner wide slot, shown
in Figure 53, of the left and right trim sides and slide two (2) into the top trim.

4. Attach the left side trim to the top trim using two (2) corner brackets
(see Figure 58 & 59) to secure pieces together. There are two (2)
main pieces to each corner bracket (see Figure 60). When installing
the corner pieces into the trim the “B FACE” sides must face each
other and the screw heads are to face out. With the bracket in place
and the top and a side trim snug together use a flat head screwdriver
to turn the two (2) screws in each corner bracket to tighten them into
the side trim first, then the top trim.
5. Attach the right side trim to the top trim using the same method used
in Step 4.
6. For 4-Sided Trim Only: Slide two (2) corner brackets into place at
either end of the bottom trim and attach the bottom trim to the
left and right trim using the same method used in Step 4, except
tightening the side trim first, then the bottom trim.
7. Ensure that the complete trim is square; if it is not, loosen the
corners, adjust the trim, and re-tighten the corners.
8. Only if installing Adjustable Surround steps 8-10: On the back side
of the trim, mark out the offset distances required for the adjustable
surround corners to create the required size. Marking the trim will
help you install the surround corners so they will be even and square.
Refer to Figure 61 and Table 7.
a) Decide how big an area the
adjustable surround will need to
cover. From this decide which size
of the adjustable surround will
meet your need. Refer to Table 1
for the Adjustable Surround ranges.
In the Table 7 example, we want to
cover an area of 25 1 /
16
” (637mm) x
391⁄4” (997mm); this falls into the
large adjustable surround range.
Note: The bottom of the keystone
and surround corners can be
trimmed to make the surround
smaller.
