Product review (1 stars): Pain
Let me tell you.  The vent is a pain.  They don't supply the extension, for free, that is necessary for masonry placement.  The vent has to be painted before placement (UV light will make plastic brittle).  It must be silicone sealed (additional expense) on the outside wall for weather tightness. It has mounting holes too close to the edge and will snap them off if one isn't careful (especially in cold and/or masonry where precise placment of the six screws can be dicey).  The vent has to be mounted precisely vertical.  The base is open-- not screened or with some sort of mesh for the prevention of critters attracted by warm air.  The installation took two hours as opposed to fifteen minutes for a typical vent and six days if you count the painting and wait for the extension.  Finally, the connection to the vent pipe is awkward AND a lint trap, that once installed, is not easy to get to, at best, at the outside wall.  That product needs big time help in installation engineering.  The Heartland people are pleasant but not helpful.  Now I admit that this vent is a good idea, but it is also a rip off with little support and NO HELP from Heartland.  Be careful when buying this it will break your spirit.  Truth is I had an existing vent hole but this took a whole bunch more work.  I had the tools to make a safe and secure install including vent pipe crimpers, but the typical homeowner will be throwing money away unless they have a good installer and/or the specialty tools and there is the very real possibility they can have a hole in the wall to boot.  Don't even think about this in masonry without a hammer drill, sharp masonry bit, and a bit of luck in the location, hardness and joint placement of the brick or block in the outside wall.  The Heartland people need to do several installs before putting this vent out to the uninitiated home installer and they will soon change their product.  The vent dryer/vent connection needs work. The vent should be pre-primed and all of the installation parts should be in the package (or free on request).  This item is a good idea but in my opinion was not thought through for convenience of installation or safety.  This is a lesson on how to make a good product bad.
