Valve Surface Surface Gas Valves & Air Shutter Orifice Gas Air SAFE SERVICING PRACTICES Air Shutter adjustment Burner Shutter Valve Orifice To avoid the possibility of personal injury and/or property damage, it is important that safe servicing practices be observed. The following are examples, but without Venturi Hood Oven Air Valve Burner limitation, of such practices. Wire Manifold Gas Safety Shutters screw Burner 1. Before servicing or moving an appliance remove power cord from electrical leads to Valve Support outlet, trip circuit breaker to OFF, or remove fuse. Spark Gas Valve 2.

Ground leads are not to be used as Fig. 4 Fig. 5 switches current carrying conductors. It is extremely important that the service technician reestablish all safety grounds prior to completion of Surface Burner Flame Adjustments service. Failure to do so will create a potential safety hazard. Pin Spud 4. Prior to returning the product to service, ensure that: 1.
