I have a Marey 10l on demand hot water heater and I need to convert it from lp to natural. Can you help me find the parts I need? Please, we are having a hard time finding.

Contact the company and see if they have any local distributors, https://marey.com/english/contact-us and see what they recommend. In addition, almost any local plumbing contractor can steer you in the right direction and order the kits/parts for you.

Have your model and serial numbers handy and ready.

This is how it's done, https://www.youtube.com/watch?v=h07cdIQGj_c

You could also call your local gas company. Gas control valves are pretty much standard between brands. Years ago (many years) when I had to do that, the gas company sent someone out to do it far me. No charge if I remember correctly.

Go directly to the source: the Manufacturer. Here is their contact info:
