    For all “raised hearth” construction - even where concrete blocks are used to create the raised platform, it is still mandatory to use the Isokern base plate. Be sure to Earthcore Adhesive the concrete block platform together. All CMU used for base plate support should be rated ASTM 90.
  • Page 21: General Assembly Instructions

    Earthcore Adhesive is then squeezed from a grout bag onto the contact surfaces of the Isokern components as they are fitted together. NOTE: It is important that a ½” bead of Earthcore Adhesive is piped onto all the components’ contact surfaces, about ½” in from all edges (Figure 9).
  • Page 22: Isokern Xcelux See-Thru Installation

    1) Apply Earthcore Adhesive to the joints between each baseplate part and ensure to set each base plate in a full bed of Earthcore Adhesive on a level support surface (Figure 11). See page 17 for information regarding the supporting floor system.
  • Page 23 Earthcore Adhesive already applied to the proper areas on the base plate. 3) Continue assembly of the consecutive courses of the firebox side walls. Apply Earthcore Adhesive to the top of each layer of side wall components before setting the next course in place (Figure 13). Look for some Earthcore Adhesive to squeeze out along the joints of all contact surfaces as a sign that the joint is thoroughly sealed with the approved Earthcore Adhesive.
  • Page 24 When properly installed, the angle iron will protrude ½” beyond the front edge of the side wall components (Figure 12). NOTE: It is not necessary to apply Earthcore Adhesive between angle and Isokern sidewall components. NOTE: The steel angle should not be longer than the width of the firebox.
  • Page 25 Begin by setting the rear Damper Beam components into place. Next, set the Damper End Blocks into place atop the sidewalls in a bed of Earthcore Adhesive. Be sure to apply Earthcore Adhesive to the contact surfaces of each Damper End Block component where it will meet the front and back damper beam lintel components. Next, set the front Damper Beams into place.
  • Page 26 February 2025 Isokern XCELUX SEE-THRU Installation 7) Set the rear smoke dome component(s) across the damper beam in a bed of Earthcore Adhesive and flush with the back face of the rear damper beam lintel. Apply Earthcore Adhesive along the top of the front damper beam along its entire length; bead should be 3” from the front edge.
