3. NOTE: Fiberglass insulation may irritate
your skin. Always wear gloves when handling.
The berglass insulation provided is heat
resistant. Your particular model may leave
some of the insulation exposed to the inside of
the replace. This is normal and should not be
of concern. This berglass is designed to
protect the metal nish of your frame. Both the
2” and 3” Fiberglass Pieces (J & K) will
separate into three strips each by peeling
them from one end as shown in Figure 3.
Measure all dimensions of the back channels
on your Glass Door. Cut insulation to length
with scissors and place in back top and back
side channels as illustrated.
NOTE: The insulation does not need to ll the
channels to their full depth. Should you prefer
additional insulation, you may purchase it from
your local home improvement center.
4. The lintel bar is the “L” shaped angle iron that
supports the bricks along the top of the replace
opening. This bar is built into your masonry
replace when originally constructed. Measure
the width of the lintel bar. If the lintel bar is less
than 3” or more than 4” wide, refer to the
Alternative Mounting Method Instructions
(Page 8) and skip steps 4-6 in this section.
To determine the proper bracket assembly for
your replace, measure the distance from the
bottom of the Lintel Bar to the bottom of the
replace. Use this measurement to determine
where the Lintel Bar will line up with the slotted
brackets on the back of your frame. If the
measurement reaches the top of the slotted
brackets, follow Bracket Assembly A. If the
measurement is not the same height as the
slotted brackets, follow Bracket Assembly B.
Assemble the Key Bracket (E) to the lintel clamp
(D) with the 1/4-20 x 1/4” Machine Screw (A).
Do not tighten. Thread 1/4-20 x 2” Thumbscrew
(C) into lintel clamp. Do not tighten.
