    Installed Fantastic fan in kitchen and guess what?

    Turned on the fan and felt air coming from under the butler cabinet, that's what I call it , so I pulled out the drawers and found a HUGE opening to the area where all the plumbing and duct work is located which would defeat the purpose of running the fan to remove heat build up as it would allow it to draw air from outside the boundaries of the living space. Here a couple pics of before and after. I just used cardboard to block off the opening which is about 95% effective.Click image for larger version.

    If I remember correctly, this is where the furnace gets its return air from, someone smarter than me can say for sure. Not sure I'd want to block it off for the cooler months if that is the case.

    You could be right, I will call Tech support on Monday and find out, even if it is it is easily removed as it is only stapled up. Thanks

    Yep, that's the only opening to return room air to the furnace.

    I think the air goes on floor level under the cabinet. Don

    I remember Janice specifically stating that the opening is for the cold air return

    My 337 is basically the same as the 303 except a little more room in the kitchen and a slide out bed. I looked behind my drawers in the kitchen today. No opening.

    I don't believe that large an opening is for return air. Very inefficient because with all of the drawers usually closed the air flow would be minimal. If they wanted to use that for return air, there would be a vent opening under the bottom middle drawer and a chase running to a smaller opening in the wall.

    The recess below the bottom drawer has no top. It provides a
    23"x 3" opening below the drawer for return air.

    Yes there is an opening but that entire space I show in the picture is open to the pass thru storage, I don't see how it could be a return air. By design return air is supposed to only recirculate air that is used for living spaces and I don't think the pass thru storage qualifies as such. If in fact they use it for that then there is a serious design flaw. I'll be on the phone with Tech support tomorrow A.M.

    The picture that you show is an opening into the utility area where the furnace is located...that area is separated from the pass-thru storage and it is pulling room air from the living space from the opening under the middle drawers of the hutch. This set-up is very typical of RV furnace installation...never heard of a ducted cold air return in a RV. They always provide some type of opening, grill, whatever to allow room air back to the area where the furnace is located and the circulating fan's open intake.
