STEP 23:
Install the lower fireback. Cut 2
each, 7” strips of ¾” square kaowool. Place the
kaowool strips between the outer ribs of the reverse
side of the fireback (left and right) as shown in
Fig.A-7. Place the lower fireback into position
against the combustion package assembly, aligning
the drillings in the lower fireback with the tapped
holes in the right and left air/wear plates. Secure
with 2 each, hex head cap screw (¼-20x1”) and 2
each, standard flat washers (¼”).

STEP 24:
Assemble the damper and the upper fireback. Place the re-gasketed
damper into its mating recess in the upper fireback. Insure that the damper
seats properly. Secure the damper shafts with 2 each, new damper tabs
and 2 each, hex head cap screw (¼-20x ½”). Insert the torsion bar through
its drilling in the upper fireback and swing the opposite end of the torsion
bar into its recess in the centre of the damper. Secure the torsion bar to the
damper centre with 1 each, new damper tab and 1 each, hex head cap
screw (¼-20x ½”). Secure the torsion bar to the upper fireback with 1
each, torsion bar clip and 1 each, hex head cap screw (¼”-20x ½”) and 1
each, standard flat washer (¼”). Operate the damper through its full range
of movement using the end of the torsion bar. If binding occurs, correct
by filing or grinding. Do not bend the torsion bar, tabs, or clips.
STEP 25:
Install the upper fireback and damper assembly. Start the left end into
position first; insuring that the torsion bar end is above the opening in the
left air/wear plate. Push the entire assembly upward into its cement
channel in the stove top. Align the drillings in the upper fireback with the
tapped holes in the right and left air/wear plates. Secure with 4 each, hex
head cap screws (¼-20x1”) and 4 each, standard flat washers (¼”).
STEP 26:
Install the damper actuator link and the damper handle rod. Place the long
end of the actuator link (with the short curved end pointing towards the
stove front and down) onto the end of the damper torsion bar. Move the
bar behind the ear of the damper linkage access opening in the left
air/wear plate. Place 1 each, narrow flat washer (3/8”) on the long end of
