Direct from the manufacturers legal department. Some idiot apparently asphyxiated themselves using a gas dryer in a mobile home. That seems like something one would really have to work at but you have no shortage of morons out there. Mobile homes I have ever been familiar with were far from an energy efficient, draft free, airtight box with no air infiltration.
Your RV furnace has similar specifications. There is a minimum square inch requirement for both the output ducting and the grate to let air into the cabinet. Air must move for these things to operate.
You are comparing Apples and Oranges. RV furnaces really have no similar requirements. The Combustion air intake and exhaust is completely handled by the outside vent/s. The Interior air is just recycled air that flows over the burner chamber. Now RV OVENS and Ranges do have interior fresh air requirements. They are exhausted INSIDE the RV. Doug
