2.4 Installation Instructions
NOTE: If your installation has exterior finishing materials greater than 1" (25mm) thick, a #HTK-EXT-FEK Finishing Extension Kit will
be needed. The extension kit must be installed to allow for thicker exterior finishing materials for proper installation and fitting of
the #HTK-EXT. Order with the appliance and venting system.
NOTE: It may be easier in certain installations to attach the insulated flexible pipe to the HTK-EXT before securing the HTK-EXT to
the exterior of the building. If attaching the insulated flexible pipe to the HTK-EXT first, the pipe would be inserted through the
framed opening during installation of the HTK-EXT. See Step 11 on page 10 for more information.

Remove the cover assembly (6) screws for installation of the #HTK-EXT base. See FIGURE 2.4.
NOTE: If you are using exterior finishing material thicker than 1" (such as stone) then you will need to use #HTK-EXT-FEK Heat
Transfer Finishing Extension Kit. Start with Step 2. If installing the #HTK-EXT with 1" or less finishing material, proceed to Step 6
on the next page.
2. Place FEK box over the framed opening in the wall. Ensure the FEK is level to ensure precipitation does not build up in the
HTK-EXT termination cap when it is installed. Attach it to the building. Verify the box remains square so the HTK-EXT can be
installed correctly. See FIGURE 2.5.
3. Seal all corners, joints, and bend lines with silicone caulk. Ensure all gaps and holes are filled so a sealed envelope is formed.
See FIGURE 2.6 and FIGURE 2.7 on the following page.
4. The wall is now ready to be finished. Finishing materials such as stone, marble, or brick can then be applied up to the flanges
of the #HTK-FEK that protrude perpendicular to the wall. This will ensure that the cap will fit into the opening after finishing
has been completed. NOTE: Outside flanges of the #HTK-FEK must not have any pressure on them from the finishing materi-
als. This could cause the opening left after finishing to be too small.
5. After the #HTK-EXT-FEK has been installed and the finishing of the wall is completed, apply a bead of silicone to the #HTK-FEK
around the entire metal flange where it would make contact with the #HTK-EXT.
