Assembly Instructions - 60”
The MAGNUM Model 60 is a custom unit made of
standard parts that are cut and fitted together in the field. The
following cut and assembly instructions identify the parts by
name and by part number, the quantity required, the field cut
dimensions for each modified component and the placement
of each part in the assembly.
Note:
At all component placement, be sure to mortar all
contact surfaces with Earthcore Mortar. Check for complete
sealing of each contact joint while assembly progresses (see
“General Isokern Assembly Instructions” on page 14 of this
manual for mortar information and instructions).
Step 1:
Base plate, part M91, two required; All require field
cutting.
Set the un-cut M91 base plate components on an
appropriate masonry foundation. Cut one base plate to 30
1/2”. (Figure 22) Set the two pieces so that the line of the
grouping is a butt joint. (Figure 23). Set the cut M91 pieces
into place. This makes for square ends. The overall length
of the base plate assembly should measure 73-1/2” and 28"
deep.
Step 2:
Side wall, part M90, eight pieces required, used
“as is”. The fire box side wall components are used without
modification. The side wall pieces stack four high on both
the left and right hand ends of the base plate arrangement
(Figure 24)
The stack of four fire box side wall components
will be assembled in conjunction with the firebox back wall
components described in the following steps.
Step 3:
Back wall, part M67, eight pieces required, to be
“field modified”. Cut the tongue off one end of each of the
four M67 back wall components as shown.
After cutting, four of these cut pieces should
measure 38 1/2” from the cut end to the shoulder of the un-
altered end (Figure 25).
The other four cut pieces should measure 22 1/4”
from the cut end to the shoulder of the unaltered end. (Figure
26)
Step 4:
Build the MAGNUM Model 60 firebox by setting a
38 1/2” M67 back wall (from step 3) on the base plate with
it’s tongue end interlocked into the firebox side wall at the
end of the baseplate.
The square cut end of this a 38-1/2” M67 back wall
component sits flush with the back of the base plate with
its cut end past the centerline in the base plate arrangement
(Figure 27).
Next set the 22-1/4” 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 22-1/4” M67
should make a snug butt joint with the square cut end of the
38-1/2” M67 component (Figure 28).
