Intermittent, sub-30ppm CO readings?
Apartment has a gas furnace and water heater. My carbon monoxide monitor is a Kidde Nighthawk. Occasionally (maybe once a month) I'll noticed a reading in the 10-25ppm range stored in memory. Is this anything to be concerned about?
(My stove is electric, but I feel like I've noticed these after cooking. Not sure if stuff burning off of the heating elements would cause them though).
