With 20,000 Btu of heat, we recommend this built-in furnace for RVs about 20' long. It will get your RV nice and toasty far quicker than a space heater, and it includes a door so the unit can be serviced from the outside.

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.
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.

Hello, neighbors and friends. Steven here with etrailer.com. Let's take a look at our Dometic RV furnace running on LP gas with an automatic pilot light that runs on 12 volts of DC current. The whole unit's rated at 20,000 BTUs. And as you can see, this particular model comes with the black access panel door. Now, we'll remove that here so we can show you some quick dimensions here.
(metal clanking) So, overall you got 12 inches wide on the front by 20 inches deep or long, however you wanna word it. And this guy is 7 inches tall overall. Now, keep in mind with those dimensions to make sure it's gonna fit your particular needs. Now, going back up close to the door. So, it does come as a two piece.
You get the plastic trim piece that will go on first, follow up by that metal black finished door, and then final with that metallic exterior piece there that has the words "hot" molded into the metal and everything. So, I wanna keep that door off so you can see the access panel and everything inside. But more importantly, a furnace is gonna quickly and efficiently heat the interior of your RV or camper, and it does replace, upgrade, or just simply add a furnace if you need one. And you'll notice as I'm spinning all these access ports, the included duct adapters would go into there. Now this is a compact design so you can mount it horizontally like we have it today.
Or vertically. It's totally up to you. It's very flexible as far as mounting. Now, it is run on propane. You got your wiring up here, two blue for thermostat, a positive and negative for 12 volt.
And under this black rubber cap is where the threaded part is to hook up the LP gas connection. This unit features a automatic DSI gas pilot light, so it's gonna reduce the risk of gas leaks and increase fuel efficiency at the same time. And it's gonna automatically relight until the heater is switched off. Now again, folks, since it's gas powered, you can use it for boondocking, it's gonna be great. You don't have to worry about being hooked up to shore power or anything like that. The blower motor and everything is a low air turbulence, so it's gonna provide quiet operation. And on the front here, there's a little LED light down in here on the control module board. That can flash if you have any faults. It would flash D, diagnostic codes rather. And then, per the instructions on the troubleshooting, you can look up what those flashing sequences mean and then troubleshoot it that way. And that being said, as far as installation, you would need a thermostat sold separately. That's a mechanical thermostat. It's not digital or WiFi or anything. It's just a basic thermostat. And I'll put that number on the screen for you. You would also need some butyl tape or RTV sealant. That's sold separately as well. And per the instructions, you could possibly need some number 6 or number 8 screws. Like a pan style head AB style self-tapping of that nature. Again, just depends on your particular installation needs. Now over here on the side I've got the two mounting brackets and hardware that comes with the mounting brackets, and that all would be accessed up here on the mounting tabs up front. So once again, folks, rated at 20,000 BTUs. It's ETL certified. This is a great addition or replacement. Dometic RV furnace black access door rated at 20,000 BTUs. I'm Steven. Thanks so much for your time. Thanks for watching and have a great day.
Installed and working hours after delivery! Worked great in 1999 Dutchman .
It was easy to get all the info I needed to select the correct heater for my 5th wheel.
etrailer was extremely helpful in navigating the myriad of choices available and determining the correct unit to purchase. We provided the BTU output and dimensions with the ductwork configuration that allowed the salesman to accurately sell the unit that (1) fit in the space provided without modifications (2) matched the BTU output (3) provided auto ignition and worked from the existing thermostat and (4) required minimum modifications for the ductwork.
The old furnace suffered from a cracked heat exchanger which set off the carbon monoxide alarm inside the camper. Carbon monoxide is deadly and could cause a fatality. We took the furnace apart and sent the heat exchanger to a welding shop for repair. The crack was repaired, but other holes were found during pressure testing. The heat exchanger was a
discontinued item for manufacturing and therefore lead to the decision to replace.
The unit cabinet required modification to accommodate a horizontal installation with a floor duct inlet that was different than the configuration provided by the factory. A new duct outlet was cut using a template from the old furnace and using sheet metal shears. The gas line required a slight modification to reroute from a side entrance to the top. The plastic connector and wiring harness were removed from the old furnace and installed on the new furnace with heat shrink connectors. The modifications took a couple of hours to complete, however the unit is installed and working as expected.
The furnace after installation is performing very well. The unit operates from the original thermostat. We have stayed in the camper for a week with temperatures dipping down to 25 degrees Fahrenheit with extremely good comfort. etrailer is highly recommended for anyone shopping for a new RV furnace.
