I want to convert this heater to natural gas. Raypak 266K BTU Digital Propane Pool Heater - P-R266A-EP-C - 009225. What parts do I need? Can I use a convertion kit for the gas valve?

ahh its a pool heater .
cant find a user manual for it
.gas
if not sure dont light it up ..till you know its safe

check your gas pressure most houses have too small gas meters add all gas powered appliances give the number to the gas company they probably will up grade yuor meter to a larger one this should take care of your problem

This issue sounds tricky. I recommend you call the Raypak technical support line at 800-947-2975 or 800-627-2975 and they should be able to help you figure this issue out. I hope this helps.

Please vote on this answer. Thank you.

Good question. Did you ever get an answer? if so, please pass on!

You would need to change the gas valve and the orifice in the pilot assembly.

If you run a search for Rheem or RayPak the site should bring you to a menu that will have most manuals.

This link may help but I think it goes to an older heater, but it will give you a start.
