How can I convert my free standing natural gas heater Model RN300TQ ,Serial#RTO3140576 over to propane?

Natural and propane are two different types of gas. Natural gas is NOT propane. Many heaters cannot be converted. Some heaters are dual fuel, meaning there would be two different hookups depending on which fuel supply you use. I am not familiar with this brand of heater, but I do work for a propane company.

Given that natural gas IS propane, not much. It just a question of finding the proper adapter.

If you want to convert to BUTANE, then, you need to increase the air to gas proportion by about 1/3.
