DM Chimney Installation - Offset Run & Brick Ledge
Offsets to the Left or Right:
When offsetting chimneys to the left or right of the firebox, it is not possible to build a support column directly under
the third offset block.
To create proper support, construct a support column against the firebox from bearing up to the level of the smoke
dome. Bridge from the column over to bearing on the smoke dome with two pieces of four inch (4”) by four inch (4”)
by five-eighths inch (5/8”) steel angle
(Figure 38)
.
On the steel angles build a masonry or steel support column up to the underside of the third offset block in the
sequence
(Figure 38)
.
NOTE:
For offset chimney block sequences that clear the side wall of the firebox below, it is allowable to support the
first offset block that clears the firebox side wall and then to proceed with supports at each third offset block thereafter
(Figure 38)

DM Brick Ledge
The DM brick ledge is a 31½" x 31½" x 3” thick, 32½” square, steel reinforced, concrete and pumice slab. It provides a
5” ledge at all four sides of the outer liner block and is designed to support masonry veneers to DM chimneys starting
below the rafters and continuing to termination
(Figures 39 & 40)
.
The component is cast with an octagonal hole in its
center so that the DM octagonal inner liner can pass through it.
The brick ledge has four 2½” holes through it that align with the hole in each of the four corners of the DM outer
