Replace Atwood 8535 Furnace With Bottom Vent In 2011 Jayco Jay Flight With New Dometic 12V Furnace
Published 08/25/2025
Question:
My 2011 Jayco Jay Flight has an Atwood 8535. The ducts come out of the bottom of the furnace. Does the DMC74MR have bottom vent knockouts too?

Expert Reply:
Michael, yes it does. The Dometic 12v RV furnace # DMC64MR includes knockout options on the bottom as well as the sides, so you can duplicate your Jayco’s original duct layout. That’s one reason it’s such a popular swap for Atwood models.
Others - if you’ve swapped an Atwood 8535, did you keep the bottom vents or reroute to the sides? Did you use additional 4" ducting for this swap?
