Tools and Materials Needed
Assembly
Assembling Vent Panel
Select the required panels.
- For window openings shorter than 23″, trim panel A to fit the opening.
- For longer window openings, assemble and adjust the panels to fit the window opening. Use type J screws (included) to fix the panels together at the proper length.
Hard Foam Shims (For Some Installations)
To determine whether you need to install the hard foam shims, place the panel
assembly in the bottom sash channel and slide it until it sits tightly against
the exterior side of the channel. Close the sash until it holds the panel
assembly in place. Align the vent hose with the panel opening. If the inside
window frame interferes with the proper alignment of the vent hose, follow the
instructions below to install the hard foam shims. Otherwise, continue to step
3.
To install hard foam shims: lf any extension panels are used, attach foam seal(s) H to the bottom side of extension panels B or C to minimize gaps. Then attach the hard-foam shim(s) G along the bottom side of the window panel assembly to allow the vent hose to clear the window frame. (See image in step 3.
Attaching Foam Weather Seals
Attach the foam weather seals D to the top and bottom sides of the panel
assembly. Attach the short foam weather seals F to the right and left sides of
the panel assembly. (Attaching the foam weather seals to the panel assembly
rather than the window sash and frame makes for easier cleanup when removing
the panel assembly.)
NOTE
Take care not to block drain holes in the exterior sill. If necessary, cut
slots in the foam seal to allow any moisture to drain out the window sill
drains.
Inserting Panel Assembly
Insert the panel assembly in the bottom sash channel as in step 2. Use care
when installing the assembly, which will now fit very tightly in the opening.
Close the sash tightly against the top of the panel assembly. For a tighter
seal, use “no residue” duct tape (not included) to seal any gaps around the
installed panel assembly.
- If needed, install the included security bracket with a type K screw.
Sealing Gap between Sashes
Measure and cut the included non-adhesive foam E to fit the window opening.
Stuff it between the window sashes to prevent air and insects from getting
into the room.
- Tip. For a tighter seal, use “‘no residue” duct tape to seal the gap between the sashes.
Connecting Vent Hose
Align the tabs on the diffuser end of the vent hose to the slots in the panel
assembly opening. Insert the diffuser and rotate it to lock it in place.
- If disconnected, reconnect the other end of the vent hose to the product by inserting the vent hose into the product with the mounting ring facing out.
- If the hose doesn’t snap into place, rotate it slightly so the 2 lines at the front align.
Positioning Vent Hose
For best results, keep the vent hose as short and straight as possible.
However, shape the diffuser end of the vent hose into an inverted U shape just
inside the window to allow any rain or condensation to drain out the window
