Your furnace is propane and has a 12 volt blower motor. You can run it plugged into power or just on your battery. Just set the stat to auto/ heat, and raise the temp. On the stat. Hope this helps

Hi Lori, Welcome!

Most furnaces in newer units (last 20 years) are pretty much automatic.
You'll need to have the propane system turned on and have propane in the bottle.(s)
You'll need a source of 12v. Either a fully charged battery or plugged into shore power as your on-board converter also supplies 12v and charges the battery.

Once you turn on the furnace, (at the thermostat) it will begin a series of automatic lighting procedures.
First the blower fan will come on and blow a few seconds. This is to prove to the furnace control board (mounted on the furnace) there is adequate 12v. Once it proves out, the furnace control board then opens the gas valve (propane) and the electronic igniter tries to light the gas. It will try to light up to three times and if unsuccessful, it will put the furnace into 'lock-out' mode and you will need to turn the furnace off and then back on to restart the procedure.

It's always best when turning on the propane system for the first time after being off for a while, to 'purge' the lines in your camper by lighting a stove burner. This assures you have removed all the 'air' from the line and appliances like the furnace, refrigerator and water heater will have ample propane supply to light within the three tries.

Also, most all appliance manuals are available online somewhere.
Take the make/model number of the appliance and do a Google search for a manual and you'll find lots of references.

Enjoy!

Lori Roy.....

Just so you know....

The blowers on most furnaces make a fair roar of a sound. It’s just the nature of the beast, so don’t think yours is the only one that makes that much sound. Also, the furnace fan uses 12 volt power and generates heat from the propane. Furnaces can kill a battery if it’s not in really good shape, and know that furnaces use propane at a fairly high rate depending on how often the furnace needs to run. The colder the camping weather, the faster the consumption.

Make sure to flow 5picker’s instructions to fire it up the first time.

Any more troubles.....just ask.

"Most" RV furnaces are Suburban, but not all. If your thermostat says Suburban on it, then your furnace is almost certainly a Suburban.

If you can find your furnace , you can verify the manufacturer. To find it, go out side and find the intake/exhaust port. Looks like this:


Then go inside to the same location. The furnace is usually under a dinette seat, maybe in a closet, sometimes under the sink.

Under the assumption it's a Suburban, I've attached a manual that covers a lot of their models.
