Notes:
1. “B” includes the 3” thick base plate. “B” is reduced by 3” if the base
plate is eliminated to create a “ush hearth”.
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
1-1/2” clearance at the sides of the Fireplaces.
4. Rough framing dimension for depth “C” allows for the required
1-1/2” clearance at the back of the Fireplaces.
The following chart of dimensions is intended to aid in the positioning
of a replace in a corner condition where the DM 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 6)
Set a DM 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 chimney through the overhead framing.
More offset blocks can be used - if necessary to align with
overhead 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 (see pages 33 & 34).
