That grate is both combustion air intake and exhaust, but it NEVER blows any air into the camper. If the intake gets blocked, the furnace sail switch won't close and the gas will never turn on.
Inside air is run through a sealed heat exchanger so that outside and inside air never mix. Pretty good design, actually!
