Hearth and Home Technologies PVLP-SLP Installation Instructions Manual page 16

If installing with finishing material less than
1 inch thick go to step 22.
Note: A PVLP-BEK kit will be needed for installations with
exterior finishing materials greater than 1 in. thick. Order with
the appliance and venting system. It will be used to ensure
that the finishing is done to the appropriate size for the low
profile power vent (PVLP) to be installed properly.
11. Assemble the PVLP-BEK kit. Bend the two sections
of the PVLP-BEK kit as shown in Figure 3.19.
12. Use the supplied screws to assemble the box as shown
in Figure 3.20. The return bend on section A should
be located on the outside of section B.
13. Place assembled box over the framed opening in the
wall with outside flanges oriented vertically and held
tight to the building exterior. See Figure 3.21.
14. Drive two of the supplied screws through opposite
ends of the two outer flanges. This will secure the
PVLP-BEK extension box to the building and allow
for squaring of the PVLP-BEK. See Figure 3.21.
15. Seal all corners, joints and bend lines with silicone
(with a minimum of 300° F continuous exposure rating)
caulk. Ensure all gaps and holes are filled so a sealed
envelope is formed.
16. If finishing material extends past the cap extension
box (BEK) more than one inch, an additional BEK is
required. Cap extension boxes may be stacked for
thicker wall applications:
• Attach first box to the wall.
• Assemble second box.
• Bend the two outside flanges of the second box
around to the inside of the box.
• Secure the second box to the first using four #8 x 1/2
sheet metal screws.
NOTICE: It is imperative that the PVLP-BEK kit be installed
squarely or the PLVP-SLP may not fit into opening left once
finishing has occurred. Also care should be taken to ensure
that PVLP-BEK is secured flat to wall.
17. 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 PVLP-BEK that
protrude perpendicular to the wall. This will ensure
that the cap will fit into the opening after finishing has
been completed.
NOTICE Outside flanges of the PVLP-BEK must not have
any pressure on them from the finishing materials. This
could cause the opening left after finishing to be too small.
18. After PVLP-BEK has been installed and the finishing
of the wall has taken place, apply a bead of silicone
(with a minimum of 300° F continuous exposure rating)
to the PVLP-BEK around the entire metal flange, as
shown in Figure 3.24 with the dotted line.
