Adding a Filter to a Dometic Propane Furnace

[teslasmuse]

I get not wanting to restrict airflow, but is there any sort of filter for this style furnace? It really pulls dust and dirt in when it's running. Not the end of the world, just wondering if anyone has heard of such a thing. Thanks in advance

You would need something that's metal due to fire issues like on a stove hood. But I think restricting the flow of heated air it may also cause the furnace to over heat. I would leave it as is.

Agree with MO. I checked suburban's site and they don't show any optional part to filter either the intake or the outflow. If you're actually getting visible dust coming from the outflow (cabin) grate/vent you might try taking off the vent and vacuuming the inside of the unit.

You need to inspect your furnace and ducting because the heated cabin air only comes from the cabin and the combustion air's intake and exhaust is outside air. If the ducting is faulty or the heat exchanger rotted, you can get dangerous CO leaking into the cabin air. It's dangerous.

the furnace works great and isn't leaking propane, they had to pull it out to install the solar controller so it's been thoroughly inspected for leaks

The issue is not leaking propane, it's if your heater is drawing outside air that would likely contain exhaust fumes from your heater (carbon monoxide). A properly functioning heater would recirculate only cabin air, but it seems like yours draws dusty outside air. My concern for you and your family is because carbon monoxide cause more than 400 accidental, non fire related, deaths in the US each year. My uncle Emile died of CO from a faulty camper heater.

fascinating assessment based on such limited information, what exactly do you think the two vents on the outside of the van are there for, decoration?

 

[rogerstg]

I know the vents' purpose, and if you knew, you'd understand my concern. Please make sure your CO detector is working.

spare me the fear mongering, thanks

Indeed, but we don’t know what Teslasmuse does inside RV, perhaps he/she generates a lot of dirt and dust with no fear.
