we are on site at the moment enjoying a break, but...our CO alarm is going off intermittently. 4:00 AM this morning the last time! We are running no gas appliances and have the Alde heating system and fridge on mains hook-up. Overnight only the fridge and
water heater are operating. Van was serviced 2 weeks ago and this has not happened previously, only change to the van has been to install better speakers into the stereo but they are further away from the alarm than the originals. Anyone for any ideas, I know
the potential dangers of CO and have vents open overnight?
