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.
1. 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 7 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 (with a
minimum 300°F continuous exposure rating) caulk. Ensure all
gaps and holes are filled so a sealed envelope is formed. See
Figure 2.6 and Figure 2.7.
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.
5. NOTE: Outside flanges of the#HTK-FEK must not have any
pressure on them from the finishing materials. This could cause
the opening left after finishing to be too small.
6. After the #HTK-FEK has been installed and the finishing of the
wall is completed, apply a bead of silicone (with a minimum of
300°F continuous exposure rating) to the #HTK-FEK around the
entire metal flange where it would make contact with the #HTK-
EXT.
