carbon Monoxide alarm going off

[Snomas]

Our first trip w/ our new travel trailer (2 months old) the carbon monoxide alarm goes off when I run the hot water heater on gas. The alarm is located 6" off the floor on the opposite side of where the hot water heater is located. Why is gas coming inside a new trailer? The alarm is a dual alarm for both propane and carbon monoxide. Its obvious that the mfgr has a problem w/ the heater installation that allows CO2 to come inside the tlr.

I'm pis#$ off and just venting.

Check your batteries voltage when it goes off as it has three detectors...one for low voltage.

It would be next to impossible for CO to find its way inside the rig from the water heater. You would need to have a huge hole somewhere in the sidewall, a large gap around the water heater mounting flange itself, or some off the wall condition where its coming in through a window or vent. I would guess a defective alarm as the ones used by the OEMS are the cheapest obtainable.

You don't have a farting dog in the rig do you?

Chemical odors in the new rig from items like the carpet.
Rig needs to get aired out good. Open vents, windows and put fan inside to circulate the air.
