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.
Orifice change must be completed by a qualified installer or service technician. 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.
