Me too, three vents in all (2 lower cabins + heads) on one diesel heater. Just be aware that adjusting the outlets to reduce flow in desired areas will affect the back pressure in the ducting and potentially make the heater stop with an error code (overheating). Ducting increases the back pressure (diameter + distance + number of bends + vents,.)
My upper cabin has it's own diesel heater with very short ducting and one vent - never fails.
All those little bits you speak of are easily available on ebay
