Can anyone tell me what chimney type this is and if the exterior is the correct match for the type. It looks like the exterior has been partially replaced.
I am also curious why they have a column supporting the chimney here, obviously the support needs to be removed but will this chimney fall down?

Does this come from a wood stove or a gas fired appl.

From the first pic, it sure looks like a typical flue pipe. What was it attached to?

It is attached to an oil fired furnace and there is also an LP water heater venting into it.

That looks to be a typical flue with a creative flashing at the roof level.

a draft test must be taken while the unit is running. It should be no less than a negative 2 {-.o2 }

Call for a Level II: That factory chimney is re-using an old larger roof flashing that was caulked in tight so it doesn't ventilate. The first pic shows single walled connector improperly penetrating a combustible ceiling with some sort of trim ring instead of a listed support box for the factory chimney with a listed transition to single walled pipe and maintaining clearances to combustibles including that ceiling. The combustible post (18" clearance) is probably because some genius stacked factory chimney right on the ceiling, punched the hole for the single walled connector and called it a day. Fire and collapse hazard. You can be sure improper chimney support, clearances, and attic insulation shield. Must have two point stability on chimney and the contact point with the boot flashing does not count.

No tape on pipe--blocks view for inspection and is not approved for that application. Any pics in the attic? That's where the real scary pics would be taken.

Very short stack, which might not generate sufficient draft. Doesn't appear to meet 3/2/10.

Is this common vent and connector sized for both appliances per the IRC? Pics of the rest of the connector and appliances?
