So we had our first good snow and cold and very wind nights in Texas panhandle. I have some issue/question with propane heater. 99% of time works great but it seems when we have high winds from a certain direction things change. The heater works but I get a loud popping noise, seems to me that all fumes not exhausting and getting a flash boom. I don’t see anything when I’m outside so can’t confirm this. Anyone else had anything like this happen ? Or know any solutions ?

Have you for certain confirmed that the popping is coming from the furnace? I ask because many people, myself included, have experienced popping noises from the landing gears when there are extreme temperature changes.

Does the popping stop when you turn the furnace off?

There is a fix to deal with it by putting an additive into the hydraulic fluid.

Yes. Not the jacks I’ve already crossed that. It does stop and only does when heater is on.

Interesting, that's the first I've heard of anything like this.

Seems when we have 30-40 mph winds at that certain direction maybe it’s blowing in exhaust tube so some unburned gas is reigniting and getting the boom. I was thinking maybe putting a turtle vent in terms over to block the wind out . Just was curious if anyone else had this problem or heard of. Something new for me

I haven't heard of this happening before either. Perhaps Suburban can help with troubleshooting this for you. One possibility might be partial blockage in the heat exchanger/ burner tube and exhaust. Either from an insect like a mud dauber or similar wasp. Might not be visible as it could be inside a ways. Higher winds could be responsible though.

Had exactly this problem a few days ago on our trip south. The high wind was coming at a 45 degree angle and the furnace went out then popped when it tried to restart with propane still running. I fabbed a right angle cardboard piece, loosened the screws on the exhaust side, not the ones close to the exhaust/intake, then pushed the cardboard in to hold it. I checked to ensure the cardboard didn't get too hot, furnace ran well overnight. The screws I'm talking about are the 4 screws on the extreme edges of the furnace cover

Maybe not totally related, but I talked to a guy parked next to us one day with a window awning on his Montana over the fridge vent. He said it was to prevent the wind from blowing out his fridge. Makes sense now, but at first I thought he had a basement with windows.
