The following chart gives important dimensions needed
when laying out two-story stacked fireplace units. Chart
dimensions assume that both the upper and lower
fireplace units sit on the same centerline.
NOTE:
Widths of both Isokern Standard and MAGNUM
fireplaces are the same. Only the depth of the firebox
and the height of the finished opening differ.

Chart Dimension Description
A:
Outside width dimension of the Fireplace model
chosen for the upper unit.
B:
Distance (taken in the direction of the chimney offset)
from the centerline of the lower fireplace to the outside
face of the eight-inch (8”) thick bearing wall underpinning
the upper unit’s floor system.
C:
Distance (taken away from the direction of the
chimney offset) from the centerline of the lower or the
upper fireplace, whichever is the larger, plus eight inches
(8”) to the outside of the eight-inch (8”) thick bearing wall
for the upper unit’s support slab.
D:
Outside-to-outside dimension of the two eight-inch
(8”) thick bearing walls underpinning the upper unit’s
support slab. “D” is also the width of the upper unit’s
support slab and includes the additional space for the
width of the DM chimney as it bypasses the upper unit.
“D” is also the sum of “B” plus “C.”
E:
Height of the Fireplaces chosen for the lower unit and
includes the Isokern three-inch-thick base plate.
F:
Distance from the top of the support slab of the lower
unit to the top of the floor of the upper unit.
IMPORTANT:
If raised hearths are planned for the lower
unit, then “F” dimension will increase by the height of
the raised hearth at the lower unit.
