Dometic RV Furnace - LP Gas - Automatic Pilot - 12V DC - 40,000 Btu - Black Door

Video Transcript for Review of Dometic RV Furnace - Black Door - DMC48RR

Hello, neighbors, Steven here with etrailer.com. Let's take a quick look at our Dometic RV Furnace running on LP gas with an automatic pilot light of 12 volts DC current, rated at 40,000 BTUs with a nice black access door panel. Now, I will remove this panel so we can take a look at the inside, and also so I can give you some dimensions. You got a nice heat shield here. Comes with a nice length of tubing. The nice metal door's been black powder-coated, nice, shiny finish.

Some foam insert there, and before that door goes on, you would actually put this plastic fascia behind the door as well, and it's got some foam and some inserts there and everything as well. So, I just wanna give you a quick look at that. I'm gonna put that to the side. Now some quick dimensions. 16 1/2 inches wide, nine inches tall, and 20 inches deep or long, depending on how you have it configured.

You can do it horizontally like we have now or vertically, so you have that flexibility of installation. And with this furnace, you can quickly and efficiently heat up the interior of your RV or camper. You can replace an old one that's broken or just upgrade, or maybe just simply add one if you don't already have one. Now, it does use what's called a DSI gas pilot. So, with the propane connection that's hidden under here and the propane hookup, that DSI gas pilot will reduce the risk of gas leaks, and also increase the fuel efficiency of the unit.

It's gonna relight automatically until the heater is switched off. It does feature a low-air turbulence, so that's gonna provide quiet operation. On that panel down there at the bottom, there's an LED light in the middle of that control board. That may flash in the future, and what that does is it's giving you a fault reading or a diagnostic code. So, per the instructions under Troubleshooting, let's say this thing was flashing, I dunno, two or three times every so many seconds, it may be telling you, "Hey, you have a bad ground", or "Hey, your gas is empty" or something of that nature.

So, just follow the instructions for any kind of fault codes to remedy that quick and easy. You have four wires here on top for wiring it up. Two blue for thermostat, red for 12 volt power, and black for 12 volt ground. So, again, great for boondocking, 'cause it runs on propane, but you only need the battery power to quickly, easily ignite that. Now, as you can see there are a lot of pop-outs along the sides, tops and bottoms. That's gonna be used with these three included duct adapters. So, depending on your needs, you'll pop them out and put your ducting in place. Two mounting brackets with some screws, and also four screws for the front fascia when you're covering it. Now, some things that I read in the instructions when I was looking at this unit that aren't really mentioned a lot online in anyone's things that I found was, you may possibly some butyl tape to put on the backside of this guy whenever you're mounting it on the exterior of the RV. That way you got a seal around this guy that's watertight, weathertight from the outside going in. That's not included. You will for sure also need a thermostat. We sell white or black. Now, these are what we call mechanical thermostats, meaning they're not digital, there's no Bluetooth, Wi-Fi access, that kinda stuff. Just a basic thermostat to control the heater on and off, and then how hot or how much heat you want out. Another thing you might possibly need, it'd be maybe some number six and number eight panhead-style screws, self-tappers that are about a 1/2 inch long. And again, that's for mounting it in place per the manufacturer. Everyone's RVs are different wall thicknesses, those kinda things, different applications, so again, read the instructions clearly before you start, and I don't think you'll have any problems. So, once again, folks, 40,000 BTUs. The whole unit's pretty light, about 35 1/2 pounds, and again, this is the 40,000 BTU with black access door. I'm Steven, thanks for watching.
