ABSTRACT:
Inlet air for a water heater used in a trailer home or camper is provided through an air tube passing through the floor of the camper to the heater within the camper. The lower end of the air tube terminates short of the ground beneath the camper and includes a cup assembly arranged to rotate about the axis of the air tube. The cup assembly has a front opening and a rear rudder. Wind blowing under the trailer home or camper will orient the cup assembly so that the front opening faces the wind so that the inlet air is passed up through the air tube. Excess air can pass out a rear opening in the cup assembly.
