2.4 Installation Instructions
NOTE: A #HTK-FEK Finishing Extension Kit will be needed for
installations with exterior finishing materials greater than 1" thick.
Order with the appliance and venting system. It will be used to ensure
that the finishing is done to appropriate size for the #HTK-FEK to be
installed properly.
1.
Remove the cover assembly (6) screws for installation of the
#HTK-EXT base. See Figure 2.4.
2.
Remove the shipping bracket by removing (2) screws on the
backside of the assembly (Figure 2.5). Remove the two screws
that attach the bracket to the inside of the HTK-EXT assembly
(Figure 2.6). Discard shipping bracket (Figure 2.7).
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 3. If installing the #HTK-EXT
with 1" or less finishing material, proceed to Step 8 on the next page.
3.
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 2.8.
4.
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 2.9 and Figure 2.10.
5.
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.
6.
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.
7.
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.
