    The manufacturer strongly recommends that wherever possible, all combustible framing materials be kept a minimum of 1-1/2” clearance from the Isokern fireplace unit at the side walls and back walls. It is the responsibility of the General Contractor to insure that listed clearances to combustible framing and to insulation are maintained throughout the construction of the project...

  • Page 19: Required Clearance To Combustible Framing

    Do not frame a wall in front of the Isokern fireplace unit. When sheathing is installed directly to the front face of the Isokern fireplace unit, be sure that when the required noncombustible finished facing materials are applied that no gaps or voids are left behind the finished facing materials.

  • Page 20: Required Clearances To Insulation And Vapor Barriers

    When STANDARD fireplace installations are surrounded by walls that are to be insulated, the walls must have enough clearance to the Isokern unit in order to maintain the three inch (3”) minimum clearance to insulation. (Figure 33) Never spray the STANDARD fireplace with any type of sealer, insulation or other material.

  • Page 33 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 components, measuring twenty-one and one-half inch (21-1/2”) wide by twenty-five inches (25”) long. The fourteen inch hole passes through the block at thirty (30°) degrees.
  • Page 34 (Figure 57) Offset block Support Foundations: It is required that every third Isokern offset chimney block in the sequence be supported down to footings via concrete block or steel support columns. (Figure 58)

Be sure to align the four 2-1/2” holes in the brickledge with the matching holes in the outer casing block below it.

  • Page 37: Brick Ledge Installation

    All DM 54 chimneys that include the DM 54 brickledge must be reinforced as described above. CAUTION: When using the Isokern brickledge it is required that the Standard firebox/smoke dome assembly include the placement of a 4” by 4” by 3/8” minimum steel angle across the firebox opening.
