Get the Btu sizing that you need

Bigger isn't always better. Getting a furnace that's bigger than you need can cause problems. A major one is that it will burn even more propane than you need.


You really only need about 1,000 Btus for every foot of RV length. For example, a 20,000 Btu furnace would be good for a 20' trailer or motorhome. That's why we'd recommend this one for a 40' trailer.


Door or doorless?

If you're installing a new furnace, the decision between door or doorless furnace will depend on where its installed and how you can get to it for maintenance or repair. With a doorless version, only the vent plate will be visible on the outside of your RV. This gives you a cleaner look, but it also means that you must be able to access the furnace from the inside of your RV.


The doored version isn't really a door, but more of an access panel that is screwed in place. You shouldn't need to access your furnace regularly, but when you do, you will need that access panel if the furnace is mounted in a place that you can't easily get to inside your RV.

Video Transcript for Review of Dometic RV Furnace - White Doored - DMC68RR

Hello neighbors, Steven here with etrailer.com. Let's take a quick look together at a Dometic RV furnace, rated at 40,000 BTUs with a white access door panel covering. It runs on LP or liqui propane gas, with an automatic pilot light that runs on 12 volts DC current for ignition. Now folks, give you a quick closeup of this. I'm gonna go ahead and remove the front door fascia. This is the heat shield.

Then you have the white metal door that has a white powder coat finish, has some foam there on the inside for cushioning, and before that goes on, you would actually put this plastic guy on first and then the door would go on last. Now I'm gonna put this to the side so I can throw up some dimensions real quick for you. Overall, it's 16 and a half inches wide by nine inches tall and 20 inches deep or long, depending on how you want to word it. Now, because this can be mounted like I have now, horizontally or vertically, you could change that, flip it over, whatever you need for your needs. Now this furnace will quickly and efficiently heat up the interior of your RV camper, fifth wheel motor home, travel trailer, et cetera, and it can replace or upgrade or just simply add a furnace if you don't have one.

Again, it is propane ran. So underneath this rubber seal here for shipping only, the connection point for the LP gas is under there and back inside and it's gonna be perfect for boondocking so you don't have to worry about shore power, those kind of things. Again, it runs on 12 volts, so you got two blue wires for wiring the thermostat up, red for power 12 volt and black for 12 volt ground. So very simple to operate, very simple to install. It's also got an automatic DSI gas pilot light, so that's gonna reduce the risk of gas leaks and also increase fuel efficiency.

It re-lights automatically until you switch the heater off and the air turbine here is a low air turbulence, providing quiet operation. Down there on the bottom, you got a nice control board that has an LED light on the middle of it. That can flash and what that would be doing if it's flashing is it's flashing faults and showing you that there's a fault, maybe it's not got a good ground or power, or it's outta gas or something, and that would give you a diagnostic flashing. You know, maybe it's two flashes every so many seconds. And then you would just refer to the owner's manual, read up on troubleshooting what those codes mean, and then you could quickly remedy that fault code and get you back going, as far as heating everything.

You're gonna get the included mounting brackets here and the screws for mounting them, along with four screws for the front fascia of the unit. Now, you might possibly need sold separately some butyl tape for putting these outside panels on to keep moisture, water and that kind of stuff in between the outside wall and the unit. You might also need per the instruction, some number six or number eight panhead style screws, maybe self-tappers even, something of that nature. You will need a thermostat to control the furnace. These are mechanical thermostats, meaning they're not digital, they're not wifi, they're just a basic thermostat. We offer them in white or black. Now as you can see, you've got two pop outs here on the front, two on the side, three along the back, two on the other side, and two on the bottom I believe. And with those, you're gonna get three of these included duct adapters, and all you'll basically do is use these when you pop out wherever you need, it pops out. And then attach your duct work in there for running your heat through the ventilation system in the RV, camper, et cetera. Once again, folks, 40,000 BTU, this is the Dometic RV Furnace, again with the white fascia door access door. I'm Steven, thanks for watching.

  • Replacement for AFMD35121 Furnace in 2018 Keystone Cougar 27SAB
    Hi Harvey; the DFMD35 series (same as your AFMD35121) has been discontinued. This leaves you with two options. You can either downsize to a 30k Btu unit or move up to the 40k unit. The 30k will fit in your existing space but you will have a little less heat. If you go up to the 40k unit it will probably require enlarging your opening since it is 2" taller. You also need to match door for door or doorless for doorless when choosing the replacement. The 40k units measure 20" deep x 9" tall...
