The DM 54 outer casing block, properly set is intended to be flush with the back face of the firebox Outer smoke dome assembly (Figure 99).
  • Page 44 DM 54 Offset Chimney Block: For vertical DM 54 chimney to bypass overhead obstructions the Isokern offset chimney block is used. Offset blocks are six inch (6”) thick, single module chimney com- ponents, measuring twenty-one and one-half inch (21-1/2”) wide by twenty-five inches (25”) long.
  • Page 45 All support columns must bear onto proper noncombustible foundations. Isokern Offset Chimney Block Installation: Isokern offset chimney blocks are stacked in a stair step fashion with each successive block overhanging the previ- ous offset block by three inches (3"), allowing the flue to rise at an angle of thirty (30°) degrees off of vertical.

  • Page 49 DM 54 chimneys. Load Capacity for DM 54 Brickledge: The sources of load delivered into the Isokern brick- ledge are: (1) the total physical load of brick, stone or other masonry veneer on the brickledge, and (2) loading due to the force of wind delivered against the exposed height of the chimney mass.
  • Page 50 The small crown cap is intended for use where DM 54 chimneys are to receive thin veneers and cultured stone that do not require the installation of the Isokern brickledge. The small crown cap is also suitable where DM 54 chimneys are to receive a stucco finish.
