I know that this chimney is against codes and furnace manufacturers instructions. I don't have any before pictures but an old gas furnace, sharing a flue with a gas water heater, was replaced with a 90+ furnace . The pvc flue, instead of running to the outdoors, was ran into the old metal b-vent stack. The lower portion of the b-vent was was rusted through (no pic). The first pic is the "fix". Just replace the rusted metal.
I am not an inspector and have no authority but am trying to get this to be made safe. The manuals were not left with the unit so I don't know how to show why a condensing furnace needs to be run in pvc to the outdoors and not in metal to rust again.
That is on top of the numerous other issues:
1) Lack of "combustion air" in the room.The intake should be run to outdoors also. no make up air for water heater also.
2) The "nice" silicone joint in the 30g metal not fire rated.
3) Water heater needs to be lined or properly sized now the the furnace is vacated.
etc.
Any links to show how to vent this furnace properly would be appreciated. The people looking at this don't understand that a condensing furnace condenses.
Thanks
