outer edge, with the top of the door tilted toward the center
of the firebox.
2. Swing the lower outer corner of the door over the hole in
the lower frame of the firebox opening, and insert the lower
pivot pin into the hole (Figure 5 and Figure 6).

5. Repeat the procedure outlined in Step 1 through Step 4, to

ALIGNING THE BI-FOLD DOORS
The doors are properly aligned when the top door trim is in a
straight, level line, and the vertical gap between the doors is even
from top to bottom.
1. Grasp one door handle, and loosen the lower door pivot pin
using a 3/8 in. open-end wrench.
NOTE: The upper door pivot pins can be loosened for
adjustment purposes. However, it is easier to loosen the
lower pins.
2. Slide the door panel on the pivot pin until the gap between
the upper door trim and upper frame is even.
NOTE: A bi-fold door adjustment kit, with washers for the
bottom pivot pins—four (4) washers per kit—is included to
assist door adjustment. The washers raise a sloping door for
a more even, horizontal trim. In some cases, adding different
quantities of washers to each bottom pivot pin results in
the best results. Install one (1), two (2), or zero (0) washers
on each bottom pivot pin, as necessary, for the desired
appearance.
3. Retighten the lower door pivot pin.
4. If necessary, repeat this procedure for the opposite door.
