FRY TOP RANGES: Fry Top Plate Adjustment: Leveling bolts are at the rear of the range under the fry top plate. Adjust leveling bolts so that the plate is pitched to the front to provide for grease runoff.

Page 9 SERVICE FRY TOP AND OVEN THERMOSTATS The bypass (minimum burner flame) has been adjusted at factory and should require no further adjustment if the gas manifold pressure is correct. THE BYPASS FLAME MUST BE RECHECKED WHEN PERFORMING CHECKOUT OF RANGE PRIOR TO PLACING EQUIPMENT IN SERVICE. THE BYPASS MUST BE SET CAREFULLY AND ACCURATELY.
