I don't have good news.
You are attempting a conversion that local technicians are refusing to do.
There is a reason why we service guys steer clear of some things: liability and continual problems afterward.

Contact Bosch and find the service bulletin for that procedure.
After all this is a highly technical and finicky machine hooked to a gas line located in proximity to people.

If this procedure is going to cost more than $400-600, and remember there is a risk it will not work afterward or will be a continual problem, then consider installing tank-type LP water heater from local box store. I recommend this.

For others in same situation: NG to LP conversions are not supported or recommended by every manufacturer. This applies to tank and tankless.
Also check there is a qualified service technician in your area before installing tankless.
Read the manual before buying.
Tankless gas savings are $1-8 per month, but all costs are energy.
Tankless cannot be exposed to more than 11 grains hardness in the water.
Tankless are maintenance heavy, and with expected repairs, maintenance and cost of parts, cost of machine and replacement cost, a simple tank-type water heater is cheaper by far.

Upvote the help.

    (1) I found service bulletin for replacing 2700ES gas valve: (2) I'm not sure what sensors have to be changed or if the PC board is changed (3) (4) When copy-pasting links from fixya, the site will sometimes add a space to end of link > here's how to fix the fixya glitch: paste link into url, highlight link so extra space can be seen, remove extra space, then link is good.

I have been getting both the FA and F7 fault codes come up day after day. I don't think it's the wiring, and I don't think both the gas valve and Ionizing components are both faulty, especially since it...

You would need to check that you have the correct burner pressure that would be part of the conversion. Its NOT all ways pre-set as some think to the correct pressure .

I need to convert this water heater to natural gas. Is there a kit available to do this?

No kits are available to convert his unit to NG. This is because the LP uses copper pipe and is within code, the NG uses black pipe and each unit is specifically designed, entirely, to use the gas associated with the unit.

My old Aquastar tankless natural gas water heater used 1/2" gas line. My new Bosch 2700ES -NG says it requires no less than 3/4" inside diameter gas line. Do I have to replace all the gas supply lines...

None !!
3/4 pipe from gas meter or regulator. At low pressure there may not be enough gas flow through a smaller pipe for the boiler when on full bore.
The boiler input pipe will be 1/2" needing a reduction from 3/4 so there is some leeway.
I have about 8' of 1/2 pipe on mine [Bosch Worcester] from the reg. and it is ok.
You could use the existing 1/2 and try. No harm done if insufficient-just replace. If you have some other gas takeoff on the same line a 3/4 pipe up to that take off is most likely.
