B a c k C o v e r. Suburban DYNATRAIL furnaces installed in recreational vehicles are classified as Direct Vent Sealed Combustion Furnaces. A forced draft furnace utilizes a sealed combustion chamber which is vented to the outside atmosphere.
The intake air for combu stion is al so taken from outdoors and is com pletely isolated from the room air. A motor is used to drive an impeller wheel to draw intake air into the chamber to support combustion and force the exhaust gases through the furnace cham ber to the outside at mos phere. A second im peller wheel (driven by the same m otor yet totall y isolated from the combustion air) is used to circulate room air across the furnace chamber where it is heated. The blower then forces the hot air into the li ving area either through a du ct system or throug h a front grille on the furnace cabinet on direct discharge models. Suburban furnac es operate on 12-volt DC pow er which is supplied either by a 12-volt batt ery or a converter system.

T he se are designed and tested under the same standards as the 12-volt models. Suburban forced draft combustion furnaces used in recreational vehicles are designed for use with Propane gas.

You shouldn't need the inverter on, most of the RV furnaces run on 12VDC, not on AC power. Has the furnace sat for long time? Does the fan come on? Or, nothing happens? If nothing, then verify the 12V is getting to the furnace. Verify the thermostat is closing.
If the fan comes on but no heat, you may have a stuck sail switch. Inside the furnace is a flap that moves when the fan runs. It makes sure the fan is running before the propane is allowed to flow.

Try blowing air through the fan vent outside of the van. A vacuum cleaner outlet makes a good air source. An air hose can work, but it can make enough air pressure to damage the furnace, so be careful. Blow in the bottom hole - stand aside, alot of dust may come out. Good luck, Mike.
On my van the only shutoff valve is at the propane tank. Mike If that's the case and I have the propane valve open, inverter on, breaker on and thermostat on with temperature set should it fire up? Am I missing something? You should hear the fan come on. Once air flow is established by the internal sail switch the internal gas valve will open to allow gas to flow. At the same time the spark igniter fires lighting the gas. If the gas does not ignite the furnace keeps running but with no heat coming out.
I always travel with the main propane valve in the closed position. If the van has been sitting for a long time the propane will have leaked out of the pipe. If this is the fan is running and there is no heat after about a minute I set the thermostat to low wait of the fan to turn off and then set the thermostat back to the desired temperature. It usually takes the furnace two or three times to get started. You can speed up the process by also turning on the one of the stove burners. You shouldn't need the inverter on, most of the RV furnaces run on 12VDC, not on AC power. Has the furnace sat for long time?
