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.
