Step 3. INSTALLING VENT SYSTEM 5” - 32” WALL THICKNESS
(12.7 cm - 81.3 cm)
a) Use only factory supplied parts. Do not attempt to modify in any way. To do so could cause a system imbalance resulting in poor
performance and/or unsafe operating conditions.
b) Slide collection box pipes through cutout & secure collection box to inside wall. Anchors (not supplied) may be required.
See Figure 5.
c) From outside house, mark collection box pipes and cut off 1/2” beyond outside wall.
d) Slide vent cap pipes onto collection box pipes and push in until flange is flush against house. Secure vent cap assembly to outside
wall with a slight downward slope. This will prevent water from entering and allow condensation to drain. Caulk around the edges
of the vent cap mounting plate.
NOTE: It may be necessary to build a metal or wood frame to provide a flat surface for the mounting plate to be flush against or
to attain the 5” minimum wall thickness.
