That is pretty ridiculous. The screen I had put on the intake/exhaust of mine has at least 10 times the open area of the air intake itself. It was put on after dirt dobbers or something built a nest inside the intake where it couldn't be seen and caused the side of the trailer to be smoked up. As a safety concern, there is more danger from a malfunction caused by the bugs than the screen. Also, if Atwood can't design their furnaces to operate properly with something to exclude bugs they aren't very smart.
