I had a radon mitigation system installed in my house prior to

Is it OK to have the radon pipe running next to the water heater
flue? I checked with the city, but they claim the code only says to
"install per manufacturer's instructions." Elsewhere I have heard
there should be 2" of clearance between the flue and anything
flammable. Is the PVC pipe considered flammable?

Thanks in advance!

From the photos, there have been some water laks in that area. If
they're not old ones, best keep watch on the situation.
