I am getting ready to install an OAK on my P43, and I am looking at the Harman version. From what I can tell, the setup includes the outside vent cap and a 2 3/8" connection for the hose. Is there a face plate or something for the interior wall? That does not appear to very clear in any of the docs I can find. It appears there is not. It must be aesthetically pleasing for my wife, or I will not be popular. (Which is why hose will be painted black) Is there another OAK that is better? I am going right out the wall in the corner behind the stove, so a short distance. Exhaust vent exits through the vaulted ceiling. Any help is appreciated. Thanks.
