Space between water heater flue and water pipes

I hope someone can explain something to me. I am in the process of selling my mother's house. The buyers had a home inspection done and one thing, among others, that the inspector noted was about the pipe insulation used at the water heater. To quote him "Plastic insulation was used on the supply lines at the top of the water heater near the opening of the flue. No combustible products can be used within 6" of the flue opening." The distance between the cold water line and the hot water line is about 8" with the flue in between the lines. The insulation used looks like a type of foam and wraps around the pipe (reminds me of a pool noodle). The water heater is in the garage and I do not think it would be a good idea to leave the pipes uninsulated. So how would the lines be insulated and still meet the 6" requirement?

I am new here, so I cannot post any photos. Thanks for this opportunity to learn a few things.

is the inspector going to make you pull the plastic rings off the pipes as well (right at outlet fitting on top are usually factory plastic grommetts)? also, the water heater comes with the insulation to be installed on the lines off the top of heater. if the manual says to butt the insulation directly to top wtr thr, it would supercede code since manufacturer specification.
you could also replace the insulation with fiberglas insulation, but even that has a paper wrap on the outer surface.

Remove the insulation.

Is there a requirement to have insulation on the pipes?

Insulation is for heat retention/minimize heat loss.

Insulation saves you money by retaining the heat in the pipe. It is negligible in your situation. The insulation does little to protect the pipes from freezing imo. It buys you a little time. If there is plumbing in an area below 32° you are asking for problems
