Working at a house this week & they’ve just installed a log burner in the living room, the metal flue goes up the inside of the existing chimney breast. I know there is a Carbon Monoxide detector required in the living room, but the breast & flue also runs through a bedroom in the room above the living room, although it’s been framed & sheeted. Am I correct in saying I need a Carbon Monoxide detector in this room as well?
