INSTALLATION - CONTINUED
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 and secure collection box to inside wall. Anchors (not supplied)
may be required. (See Figure 8).
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 and 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.
