I didn't smell anything... but did smell a very slight odor when I took a sniff under the cushion on the water heater side. Turned it off of course and the detector reset. Went for a wonderful walk on the beach for a couple hours - returned and tried it again. After the water heater was turned on the detector went off again after 5 minutes or so.
I don't know if it is the water heater, the line or the connection - have emailed ETI for guidance. Anyone have this happened?
When I had the 17, I had the propane detector go off during conditions where the wind was blowing into the water heater. With the 21, I've had both the propane & CO detectors go off during the same windy conditions.
With the CO detector, I first thought it was bad, but after the second time decided it was the water heater. I switched to a separate CO detector that has a read out & it stayed on 0 on a calm day, went to 300 during a windy one.
