Natural gas or propane? Doesn't really matter - When you press the pilot light button and release it does the pilot stay lit?

ok, first thing that comes to mind is pressure. does the pilot light make any noise sort of like the whooshing from a propane torch tip? If it does then the regulator is set too high. The flame should sort of just dance on the tip of the pilot orifice. Next will be the air/gas ratio. Too much gas the flame tips will be yellow or orange. Natural gas or propane should be a nice blue color when the air/gas ratio is right.

Ok Know How Do You Adjust The Regulator, Because Somtimes When I Watch The Flames It Turns Orange Thanks For Your Reply

the regulator is something that isn't field adjustable. natural gas is adjusted for a 4-5 in water column and propane is a 10 inch water column. the main valve mixes air with the gas to give a burnable flame. the pilot flame is of a very low pressure so it just sits there burning. the force of the air/gas mixture that comes out of the main burner shouldn't be that great that it blows out the pilot flame. another thing that may have something to do with it is a high velocity draft through your chimney. the draft is nothing more than a vacuum up through your stack.
