BURNER FLAME
All orificing and pressure setting was done at the factory and, with correct supply pressure will provide a safe, efficient source of heat. If installed above 2,000 ft. elevation, the main burner orifice must be changed. See orifice chart on Page 10 for correct size. If there is any question about the manifold pressure, have a qualified serviceman check using a manometer. The manifold pressure should be 3.0” w.c. for natural gas and 10.0” w.c. for L.P. gas. A proper burner flame will have a soft blue outer mantel approximately 3.5 in. tall with a darker blue inner mantel approximately 1/4” tall.
