Specialty Applications - Two Story Stacked Installations (cont.)
The following chart gives important dimensions needed
when laying out two story stacked MAGNUM fireplace units. Chart
dimensions assume that both the upper and lower fireplace units sit
on the same centerline.

Chart Dimension Description:
(Figure 123)
“A”
is the outside width dimension of the MAGNUM fireplace
model chosen for the upper unit.
“B”
dimension represents 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 support slab.
“C”
dimension is the 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”
is the 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 54 chimney as it bypasses
the upper unit. “D” is also the sum of “B” plus “C”.
“E”
is the height of the MAGNUM fireplace chosen for the lower
unit and includes the Isokern three inch thick base plate. “E” is
seventy inches (69 ½” actual) for all of the MAGNUM models.
“F”
is the dimension from the top of the support slab of the lower
unit to the top of the support slab of the upper unit. “F” dimension is
equal to “E” dimension plus six inches (6”) for the thickness of the
upper slab, plus six inch (6”) thickness of every offset block needed
to make the required horizontal travel distance.
Notes:
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.
In the interest of clarity the drawings on pages 58 and 59
(Figures 121 & 122) of the offset chimney sequence do not show the
offset block support columns as required for offset sequences. See
page 47 for complete offset support instructions.
Consult local structural engineer for support slab load
calculations.
