Hi , I have two co 1 alarms on nb, this year, I had problems with Morso stove. Kept on getting smoke blowing back into boat.
tried a few different ways to stop it. Eventually found the problem , and sorted it with a cowl on top of chimney. All good.
however when trying to sort it unsuccessfully initially, my alarm went off during the night. Well one did the other didn’t but was showing a lower reading. Since then I have been keeping an eye on the more sensitive alarm. It reads between 18 and 27, the higher reading causes headaches and I have to open windows overnight, 18 is usually the morning reading.
is this normal .?
should it be 0 all the time ?
Had the stove 9 years, never noticed a problem before, but never monitored it before.
would be interested in others findings and views.
