1. Cut a square hole for the tailpiece through the wall to the minimum dimensions given in Table 3, "Installation Hole
Dimensions" (note that the tailpiece is offset from the actual termination).
2. Apply a bead of the supplied silicone sealant to the back, top and sides of the riser section mounting flange.
Mount power vent to the wall. Make sure to pass the flexible conduit and pressure tubing through the wall. Make
sure to keep the outer pipe centered in the hole. (See Figure 6)
3. The power vent must be secured to the outside wall with stainless steel or galvanized lag screws (not included) or
other appropriate coated weatherized fasteners. Flash and seal the edges of the power vent mounting plate to the
wall with exterior sealant as necessary to prevent water entry behind the riser.
WARNING: DO NOT enclose or restrict the outside power vent body. This results in reduced cooling which
can create a fire hazard! Wood or vinyl siding should be cut so that the unit mounts directly on the wallboard to
provide a stable support. If the siding is greater than 1/2" thick use a spacer plate or board behind the power vent
mounting plate. (See Figure 5)
Two-Piece Backing Plate Installation:
a. Position Upper Backing Plate Half on the inside wall. Place plate half on inside wall and up to the vent body. At
the same time. Put the air pressure sensing tube through small slot and flexible conduit through larger slot, as
shown in Figure 7. Install an appropriate fastener in the upper right corner hole in the plate half.
b. Cut off or bend the two tabs of Lower Backing Plate Half inward (See Figure 8) and position it on inside wall as
shown in Figure 9. Install appropriate fasteners through the upper left and lower right corner holes in both plate
halves.
c. Install an appropriate fastener in the lower left corner hole.

Determine wall material type Combustible or Non Combustible.
(Maximum wall thickness: 8")

Combustible Wall Material: cut a square hole through the wall 2"
larger than the outer pipe diameter of the power vent. When installing
through combustible wall with insulation, the insulation must be
physically secured 1" away from the power vent wall liner.
 Non Combustible Wall Material: Cut a square hole through the
Figure 4
wall 1" larger than the outer pipe diameter of the power vent.
