Question about Heating & Cooling
I have been told that you can change a heater to accept natural gasby changing an orifice . is this true?
Yes. the orifice has a tiny hole in it.It is located at the tip of the pilot before the flame, and at the tip of the injectors. Natural gas and propane molecules are different sizes in the vapor state. The orifice regulates how much vapor comes out. You need to change the orifice in the pilot and the burner injectors for it to work properly. If you don't you will get a very large flame or a very small one, depending which way convert from. If you have the papers from the company that made the heater, they should be able to help you changer over. You also may need to make some adjustment if you are at high altitude, 2,000' or more, as the air is thinner (less oxygen) so the regulator needs to be set to higher volume.
