I may be wrong, but the exhaust air venting to through the roof is incorrect. I dont think you're supposed to use the existing metal vent with Rinnai venting. The home owner should check the instruction manual or call Rinnai customer service. I have an indoor Rinnai tankless, and it clearly states, "Do Not combine vent components from different manufacturers. " Do Not connect the venting system with an existing vent or chimney."

Rinai system call for Ranai vent pipe all the way through the roof. This could work for a part time; but could fail and cause error codes. But I am curious if this is allowed in Texas by code. But was interesting to watch

They should also insulate the lines. Those could easily freeze in an unconditioned attic (yes, even in Texas). You might even want a warming wrap.

What do you do with the discharge line off the old tank water heater? Mine has 2 water lines, gas line and a discharge on the side of the tank close to the top

That’s the pressure relief valve. It’s relocated on the bottom for the tankless water heater.

Fernco connected to galvanized steel on a tankless heater? Better make sure they have a carbon monoxide alarm in that attic

With high natural gas prices they are a no brainer
