The damper support pair at the front of the rebox
opening will be set into the 4” x 6” steel angle from Step 7
(Figure 56).
Since the inside corner of the steel angle is rounded,
it is a good idea to round the bottom front corner of the
damper support to match the steel.
With the bevel cut ends of the damper support pairs
meeting at the middle of the rebox, the bevel joint should be
an even and good t. The damper supports overall installed
length should be 85 1/2”.
Notes:
A. Do not join the damper supports with a butt joint. The
bevel joint discussed above is the REQUIRED type of joint
for the damper support.
B. The bevel angle of 15˚ is a convenient angle and is given
as a suggested angle. The angle of bevel could be different
just so the angles cut in the adjoining damper supports join.
C. The angle of the bevel cut could be greater just so the
bevel cut in each damper support joining pair is the same
angle in order to have a good t at the joint.
Step 11:
Damper support (left), part M64L and damper
support (right), part M64R, one each required. To be used “as
is”.
Set the damper support (left) and the damper support
(right) into place on top of the rebox side walls in between
the front and rear damper supports.
Each of the damper supports, right and left, is
designed specically for its own side of the unit. When
properly set, each damper plate side piece sits ush with the
outside face of the rebox side wall. The interior bottom edge
of the damper support end pieces align with the angle of the
interior of the rebox side wall (Figures 56, 57).
For the MAGNUM Model 72 the smoke dome
components stack two tiers high giving a smoke dome of
approximately 32 inches in height.
Step 12: Smoke dome top large, part 13, six required, to
be “eld modied”; smoke dome top medium, part 11, two
required, to be “eld modied”; smoke dome top sloping,
part 34, four required, to be used “as is”.
Begin building the MAGNUM model 72 replace
smoke dome by cutting the haunch off of one end of each of
the four smoke dome top large components, part 13. After
cutting the bottom length of the piece will be 49 3/4”.
When cutting the haunch off be sure to follow the
angle of the sloping end in order to get the proper slope angle
to the cut (Figure 58).
