Question 1

Is it better to mount it low or high when establishing a transfer with the basement stairs?

Accepted Answer

I would imagine if it's for basement stairs, it wouldn't really matter. I'm not a professional though.

Question 2

I received the product and the baffle is made out of cardboard. How am I supposed to clean cardboard? This could also lead to mold/ mildew issues.

Accepted Answer

Compressed air would be suffencent to blow through and remove any contaminates.  Card board is on sheet rock in the walls already and with all the airflow I seriously doubt mold would ever be an issue. Typically mold requires moisture and restricted or no air flow to thrive

Question 3

Is this a Through Wall install to be used between rooms?

Accepted Answer

Unless one room only has a supply vent and the other room only has a return vent, there wouldn't really be a benefit of installing this item in a wall between said rooms.  The only exception would be if a whole closed-door room is an obstacle out to the open area.  Then you'd need two of these to install on opposite walls to create a full pass-through.  At any rate, most cookie cutter houses have supply vents in every room, and only one large return out in a hallway or common area.  So, this product is more so intended to be installed through the wall between a positive pressure area (such as a bedroom with only a supply vent and door) and a negative pressure area (such as the hallway or open area where the return is).

Question 4

Where are the installation instructions in the box? I can't find what size openings to cut, how to align both cuts, where to locate the vent, etc.

Accepted Answer

To my recollection, instructions were not included. I chose an approximate desired location in my wall, located studs with a stud finder, and outlined the hole using one of the flanges and a level. Once cut though on one side, I marked the inside of the wall for the second cut. If you do not feel comfortable with the project, contact a handyman … shouldn’t take more than an hour per vent.
