Next set the 34-1/2” inch cut M67 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” M67 should make
a snug butt joint with the square cut end of the 38 1/2” M67
component (Figure 51).
Step 6:
Continue stacking the remaining three courses of
back wall. Be sure to reverse the positions of the 38 1/2”
M67 and the 34-1/2” M67 in each successive course. In this
way, the butt joint where the two M67 components meet are
staggered from course to course.
The overall width dimension at the back of the
firebox should be 85 1/2” (Figure 52).
Step 7:
Steel angle of 4” x 6” x 5/16”, one each required, 85
1/2” long.
A 4” x 6” x 5/16” steel angle needs to span the top
of the MAGNUM Model 72 firebox opening.
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 53).
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 53)
Mortar between the steel and the notch in the top of
the side wall is not needed.
Step 8:
Damper support (front & rear), part M69, four
required, to be field cut to fit.
Bevel cut one end of each of two M69 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 54).
For best results a 15˚ bevel angle is suggested.
Step 9:
Bevel cut one end each of two M69 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 55).
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.
