Ignore the brick chimney on the right. It’s already a reported defect with an oil fired forced air furnace sharing the same flue as a supplemental wood fired forced air furnace. Creosote is type of liner, right?
I’m concerned at what height is a sectional chimney needs support? Guy wires or otherwise. This one measured from the high side is at 93". It’s a DLR (doesn’t look right) to me. Any suggestions? Thanks!
