          What are the outside dimensions of item no. 30839 coleman ducted grill and what comes with it ?

Asked by: Ernie Zwiener
Without measuring it, about 16 inches on each side square, Holes in 4 corners just inside 14 inch standard opening in your ceiling. Metal frame and 4 long bolts included to attach the AC to your roof. Follow instructions. Metal panel to plug cold air side to force air into your camper ductwork. Insulated inch thick plug to separate intake and output air path. Get some foil tape to seal airflow between in and out air. Again follow instructions. I ALSO SEALED SERIOUS air gaps around camper ductwork with foil tape so do not lose cold air into the ceiling. Air filter included is thin flimsy junk but I used it anyway. Did make and add 1/2 inch hardware cloth wire grill to keep filter in place. Bout 6 by 14 inches attached with 4 small screws to metal mount frame. Surprise was included control box to be operated by your wall mount Coleman thermostat. Camping World did not have this control box in stock when I ordered this grill and didn't know it comes with the grill. That extra item does explain $145 price for the grill kit. They also did not have my thermostat, ordered from another supplier. Digital thermostat needs 6 strand control wire. My camper came with 4 strand control wire. I found 7 strand wire at Lowes. Pulled it through with difficulty. Not included were 4 screws 1 inch long to attach plastic grill to your ceiling . Grill does not attach to metal frame as I expected but completed install looks good and is very quiet compared to original AC unit. It also cools very well. Good luck.
