Atwood AFMD30121 Exhaust Vent
Hello, I have been fighting a shooting issue with my furnace since I purchased my trailer. I’ve replaced the orifice and the heat exchanger thinking a clog of some sort. When I had everything disassembled I noticed the exhaust vent tube is for an AFSD20 series not an AFMD30. My guess is that the ring inside the tube has too small of a hole to let enough air through to achieve the proper air/fuel mixture. Does anybody know if the correct vent tube is available for my furnace? I believe it is Atwood part number 30583. Does anybody know the correct tube opening for the larger furnace? I’m sure I can have it machined if needed.
Thanks
