This will replace your broken or worn out Dometic RV furnace. This doesn't include a backing plate or access door needed for a new installation. With 40,000 Btu of heat, we recommend this for RVs about 40' long.

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.

(alarm sounding) Hello, neighbor, Steve here with etrailer.com. Today we're taking a look at our Dometic RV furnace running on LP gas with an automatic pilot, 12 volts of DC current for that pilot light. This whole unit's rated at 40,000 BTUs and it's what we call a Doorless model or it doesn't come with an access door. Now, some quick dimensions on this guy, it is 16 and a half inches wide, nine inches tall overall, and it's about 20 inches deep or long depending on how you wanna word it. Now, this is gonna be great to quickly and efficiently heat up the interior of your RV or camper. It can replace, upgrade again or just add a furnace as needed and it is a propane-powered unit.
The propane connection's (object knocking) underneath this rubber tab here for shipping, and it is gonna be great for like boondocking because you won't have to worry about shore power. You just simply need 12 volts of power for the automatic DSI gas pilot ignition that's in there in the back. Now, that is also going to help reduce the risk of gas leaks. It's gonna increase your fuel efficiency and it relights automatically until the heater is switched off. The blower is a low-air turbulence and it's gonna provide quiet operation.
And as you can see, again, it's a doorless compact unit. It does have this little heat shield, (shield scraping) if you will, that goes on the outside of your camper, RV, fifth wheel, whatnot. And you would wanna put some butyl tape behind this point whenever you're putting it on the outside of your camper or RV or whatever. Now, that being said, if you want to purchase a door sold separately, you could do that, and it also would require the use of a thermostat to control the furnace, itself. Those thermostats that we offer in black and white are what we call mechanical thermostats.
So, they're not gonna be digital or anything like that, so just keep that in mind. You get the four wires here, two blue for the thermostat, red and black for power and ground. And on the front panel down here, there's a control panel module board. That has an LED light that can flash if it has faults, and it would give you a diagnostic code, like a certain flash sequence. And that will tell you in the instructions what to do if you get a certain sequence, whether it's, I'm outta gas or I'm not getting 12 volts of power, I'm not grounded, something of that nature.
Now again, it is ETL-certified. (object knocking) It can be mounted like it is now horizontally, or you can flip it and mount it vertically. It has that flexibility, totally up to you. You are gonna get three of these vent duct adapters. You got two on each side, two on the top, two on the bottom, three on the back as far as punch outs, depending on what your needs are. And as you can see, you've got these little L installation brackets that come with it for mounting it, and those would most likely go on these top tabs here. Well folks, I think that's gonna wrap it up, just a quick look at our Dometic 40,000 BTU-rated Doorless furnace. I'm Steven. Thanks for watchin' and have a great day.
Installed and working hours after delivery! Worked great in 1999 Dutchman .
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.
It was easy to get all the info I needed to select the correct heater for my 5th wheel.
