Notes:
A. “B” includes the MAGNUM 3” thick base plate. “B” is reduced by
3” if the base plate is eliminated to create a “ush hearth”.
B. “Raised hearth” requires additional rough opening height at “B”
equal to the height of the raised hearth detail.
C. Rough framing dimension for width “A” allows for the required
1-1/2” clearance at the sides of the MAGNUM replace.
D. Rough framing dimension for depth “C” allows for the required
1-1/2” clearance at the back of the MAGNUM replace.
The following chart of dimensions is intended to aid in the positioning of
an MAGNUM replace in a corner condition
where the DM 54 chimney must turn 45° degrees to align with overhead
framing.

To turn ue 45°, rst set one offset block on the rebox so that
the chimney offsets 3” toward the back of the rebox. (Figure 5)
Set a DM 54 outer casing onto this offset block so that the outer
casing is at 45° to the rebox and square to the overhead framing system.
Run the vertical DM 54 chimney through the overhead framing.
More offset blocks can be used - if necessary to align with
overhead framing - before running the vertical DM 54 chimney outer
casing and liner.
Note: Support the third offset down to footings and at each third offset
block thereafter (see page 47).
