Water heater flue - is this allowed?

[Mike G. Krueger, 2344]

Other than the improper slope of this flue (a ¼ inch per foot). Is this small flue to large flue acceptable? Any other issues with this?

Thank you

PS Thank you very much too all the vets!!! I appreciate the sacrifices you made. I enjoy my freedom too!

A 90 degree turn at the outlet of a fuel burning appliance is never a good thing. Is the c vent portion too close to combustible piping (<6")?

The c-vent is about 5" from the pvc and about 7 to the floor joists.

Thank you Rick
