Furnace Jet engine whir noise

[gunrock]

Hello, I have a 2023 Rockwood 2606ws. It's not as loud inside, but outside it's very noticeable. When the furnace runs, it almost sounds like a jet turbine. Is this normal on newer furnace units? If so, I won't worry about it. Thanks.

Yep...seems so.
My new CC 315IK furnace sounds just like it and my buddy's Montana furnace is even louder!
When we camp together I can hear his fire up every cycle inside our R/V.
Neither of us have screens.

the propane nozzle of your furnace is just like a mini jet engine many times when camped with other folks I have said to my other half its either their furnace or water heater that just started when she mentioned the sound.

Yeah thought there was a post on here asking for the model, I don't have the specific model, but it's a Suburban 35K BTU furnace. It worked fine otherwise, all week. Heats fine, cycles fine. The gas regulator has not been an issue. Someone on Facebook mentioned flame adjustment. I might ask the dealer about it when I go in, but based off comments here and others, I assume the high output of the Suburban is where the noise is from. I can faintly hear it on my in-laws 2020 5th wheel Rockwood. It's Suburban also. I assume it's not as loud due to acoustics. If i find anything out from the dealer, I will keep you posted. Thanks all.
