Ventahood mystery solved (attention all VAH owners)
See my earlier thread for background: http://ths.gardenweb.com/forums/load/appl/msg101923329543.html?21
The distributor was very, very helpful and after receiving their first call about my problem on Thursday sent an actual VAH rep this morning. Yesterday was a holiday here.
I know there are quite a few of you with similar issues of the internal dampers not opening fully. Turns out that when the unit settles into place the box shifts a bit, meaning that the little plastic dampers were catching on the lip of the duct opening.
I scored about 1/4" off the side of each damper with a utility knife and that was that. They now open fully (i.e. swing 6" all the way up until they are vertically pinned in their housing) on both low and high.
I love easy solutions and I love good customer service. Everyone who owns a VAH should get out a flashlight and look up at your dampers when the fan's on. If they're not opening all the way they're not performing optimally.
Now if I could only get my Wolf sorted out.
