Next set the 34-1/2” inch cut # 67 piece so that its tongue
end interlocks with the side wall component at the opposite
end of the base plate.
The square cut end of the 34-1/2” # 67 should
make a snug butt joint with the square cut end of the 38
1/2” # 67 component. (Figure 43)
Step 6:
Continue stacking the remaining three courses of
back wall. Be sure to reverse the positions of the 38 1/2” #
67 and the 34-1/2” # 67 in each successive course. In this
way, the butt joint where the two # 67 components meet are
staggered from course to course.
The overall width dimension at the back of the
firebox should be 85 1/2”. (Figure 44)
Step 7:
Steel angle of 4” x 6” x 5/16”, one required, 85
1/2” long to span firebox.
This steel angle sits on top of the
uppermost side wall component with the four inch leg in
the horizontal position. To avoid a thickness problem with
the placement of the steel angle it is necessary to cut a
notch in the top side wall component where the angle is to
sit.
This notch should be cut approximately 5/16”
deep. The notch should start at the front face of the side
wall component (at both the left and right hand walls) and
run to a point four inches back toward the firebox.(Figure
45)
The steel angle sits in this notch. The six inch leg
of the steel angle is in the vertical position and is to be
located in alignment with the front of the firebox. The ends
of the steel angle should not protrude beyond the outer
firebox side walls. (Figure 45)
Mortar between the steel and the notch in the top
of the side wall is not needed.
Step 8:
Damper support (front & rear), part # 69, four
required, to be field cut to fit.
Bevel cut one end of each of two # 69 damper
supports to 44” in length from the long point of the bevel
cut to the un-cut square end. The long point of the bevel cut
is to be at the top of the damper supports (Figure 46).
For best results a 15˚ bevel angle is suggested.
Step 9:
Bevel cut one end each of two # 69 damper supports
to 41 1/2” with the long point of the bevel at the bottom of
the damper support. The bevel angle must be at the same
angle in this case, 15˚ - to match with the bevel angle of the
other damper supports already cut in Step 8. (Figure 47)
Step 10:
Set the cut damper supports along the front and
along the rear of the firebox using one of each of the cut
pieces (one with the long point at the top of the piece and
one with the long point at the bottom of the piece) together
as pairs.
