Ever Hear of this Happening? Smoke alarm question

First time out in brand spanking new RV. Camped in the White Mountains National Forest in New Hampshire. Came to bed time, set the thermostadt to 55 degrees and went to sleep. 2:00 AM the furnace comes on. 2:02 AM the smoke alarm comes on. Not a pretty sight me hopping up to shut down the furnace and open the roof vents and turn on the fans. The unit was not filled with smoke, no odors I couldn't believe were just because 'new'. Aired out by 2:10, went back to sleep as the interior temperature approached 38 degrees. Turned thermostadt back on, same results, same comic episode.

Tried again at 7 AM, same. Got home after 250 mile drive. Same.

id assume its from either the crap they leave in the vents or something is in the furnace that should not be there. Dealer time!!

Sounds like it could be a defective smoke detector that is sensitive to the heat or possibly the dust that the furnace stirred up when it went on. I would replace the smoke detector first and see what happens.

your dealer should have told you to run the furnace for awhile, before you went out.

this should be standard recommendations, since the new furnace needs to burn off residues.
i was told this by my dealer and it's discussed many times on RV forums.

what you experienced is common for new owners that don't do this.

by the way, next time you should post this type of question in the General Tech and Repair section here at FRF. not under the Travel Chat section.
you'll get more responses for this type of issue.

you also want to burn off the oven. ours smoked really good. I was lucky enough to do it at my house when I was working on the camper, I took the batteries out of the smoke detectors and turned on the bath fan.

Thats normal - we had the same thing happen and I should have thought of it. I work for an HVAC company and everytime we install a new furnace or replace the heat exchanger in one, we have to burn off the heat exchanger. The heat exchanger when it manufactured has some oil residue on it from the manufaturing process. When it gets hot it burns off slowly. Open all your windows and pull the smoke detector and crank the stat and run for a while after the smoke stops.

Dealer have burnt the furnace in for an hour or so to burn oil out of the furnace. Part of the PDI we pay for. Our Edgewater when we got it the dealer forgot and it scared the bejeeze out of us. I made sure and asked them about it when we did the walkthrough on the V-Lite and they showed us it is part of the check list for them to do.

Yep, run furnace and oven for a while with windows open. When we took our unit home last spring we ran the furnace and oven to clean out the junk. Are you sure its the smoke detector and not the CO2 detector going off?

Thanks everyone! I opened all the windows, started all the fans, set the oven to 500 degrees (more like a kiln), and set the thermostadt to 83 degrees. The smoke detector chirped a few times and fell silent after 10 minutes. After 40 minutes I started closing windows and shutting down the fans. Left the furnace and oven on for an additional 20 minutes and not a peep. Shut everything down and repeated an hour later. No more smoke alarms! Won't experience this again until my wife makes her famous casserole.

Saved me bringing the RV back to the dealer and all the drop off pick up hassle.
