More detailed pics would be great. But I can tell you right now, there's an issue with clearance to combustibles. Is that top vent connector a B-vent (double walled)? It should be!
Also, that charred OSB is definitely yelling for help. The vent connectors are either getting extemely too hot because of the "horizontal" installation
(that you described) or the pipe that is penetrating the sheathing to the exterior is not installed to the 3-2-10 rule, and is causing the exhaust fumes to be blown right back into this area.
What is this vent connector exhausting?
This chimney definitely needs attention!
