Why line chimney?
I understand it is safer and more efficient. Just for knowledge reasons I am asking. We converted to natural gas and lined the chimney. The old boiler had about 3 feet of vent pipe. It went up 2 feet and elbowed 1 foot into the brick chimney that went up the center of the house. When we first moved in I installed CO/smoke alarms in every room that the chimney traveled through just in case of cracks or leaks in the chimney walls. When we converted I was told natural gas must be piped up the chimney. I'm curious is co from natural gas different from co from oil? isn't carbon monoxide the same either way? Would have every one in the house slept "very well" if you know what I mean if we had vented the new boiler the same as the old?
