				Orifice (Manifold)
Gas Type	Main Orifice I.D.	Pilot Orifice I.D.	Supply (Inlet) Pressure	Pressure
Natural	0.0935” (2.3749mm, #42 drill)	0.018” (0.46mm)	4-7” W.C. (9.95-17.4mbar) *	3.5” W.C. (8.7mbar)
Propane	0.0520” (1.3208mm, #55 drill)	0.018” (0.46mm)	11-14” W.C. (27.4-34.9mbar) *	10.5” W.C. (24.9mbar)

*The gas supply pressures shown are for ovens installed in North America. The required gas supply pressures of other locations are dependent on the local gas type and on all applicable local codes.

IMPORTANT

Additional electrical information is provided on the oven's serial plate, and on the wiring diagram inside the machinery compartment.
