Width - A
Height - B
Depth - C
Model 28

61 ½”
29 ½”
Model 36

Model 42

Model 48

NOTES:
1.
“B” includes the 3”-thick base plate.
2.
“Raised hearth” requires additional rough opening height
at “B” equal to the height of the raised hearth detail.
3.
Rough framing dimension for width “A” allows for the
required 1½” clearance at the sides of the Fireplace.
4.
Rough framing dimension for depth “C” allows for the
required 1½” clearance at the back of the Fireplace. 29½"
is only for an interior wall as most exterior wall framing
have insulation, even if the wall is 2 x 6, the foam they
spray expands, so typically 31" is allowed on an exterior
wall

Corner Installation Framing Dimensions
The following chart of dimensions detail the positioning of
an MAGNUM Series fireplace in a corner. It also
details the positioning of DM chimney where it must turn
45° degrees, if alignment is needed to overhead framing

To turn flue 45°, first set starting inner liner onto the top
plate of the fireplace.
Next, set a DM outer casing onto the inner liner so that
the outer casing is at 45° to the firebox and square to the
overhead framing system. Run the vertical DM chimney
through the overhead framing.
Offset blocks can be used, if necessary, to align with over-
head framing before running the vertical DM chimney outer
casing and liner.
NOTE:
Support the third offset down to footings and at
each third offset block thereafter.
