I'm not sure what the best way to describe this is, but here goes...
I have 2 problems with the heater boxes and cables in the RV-14.
1) The doors don't seal well, so definitely take the time to put a very thin RTV seal bead on the firewall when you are building, to help those vents seal when closed. Mine leak and in the summer it isn't great because when it's 90F outside the last thing you need is more heat coming in.
2) Now that I'm into the season when I need to use cabin heat, I'm glad that it does seem to work well as far as the amount of heat available. But what isn't working for me is the push-pull cable. The way the heater boxes work, if you have the vent door 1/2 open, the airflow will try to shut your vent for you. The push-pull cable detents aren't enough to keep the vent in mid-travel position. Does anyone know a way to "tighten" that up? I don't think there's any adjustment but can something be wrapped around the shaft or maybe shoot some type of glue into the cable detent area that may help add some friction? It wasn't even that cold out the other night but ever 3 minutes I had to pull the heater open again to keep the cabin temp up. If there was some sort of friction adjustment, I think it would have been fine.
I'm going to have to get a fix for that in place within a month or it isn't going to be fun to fly up here in WI.
