SPILL-PROOF SEALED BURNER
Brackets are mounted to the under side of the cooktop by T-15 Torx screws.
The screw heads are located under burner head (these screws must be removed
before lifting the cooktop). Screws and bracket ensure proper alignment for gas
to be injected into the burner head. It is critical that brackets are aligned correctly
and screws fully torqued down during final assembly.
REPLACING ORIFICE HOLDER AND TUBING
The Orifice Holder and Supply Tubing are one assembly.
To replace the assembly:
• Follow the instructions under To Remove the Cooktop.
• Remove the 5/8" nut securing the orifice holder being replaced to the bracket.
Use a 5/8" open ended or adjustable wrench to loosen the nut.
• Loosen the 1/2" nut securing the tubing to the valve.
TO REMOVE COOKTOP
• Remove grates, burner caps, and heads.
• Remove T-15 torxs screws - 3 under each burner head.
• Disconnect electrode leads.
• Disengage 2 front clips using a flat blade screw driver located between cooktop
and manifold approximately 2-1/2" from each side.
• Lift top up at front.
• Shift top left or right to disengage hinge pins at the rear.
IMPORTANT: Before lowering the top onto the front clips, line up the burner bracket
with the cooktop to replace screws.
NOTE: When reinstalling top, position top to be the equivalent of 1/2 way lowered
before attempting to insert the top hinge pins into the corresponding slots on the
backguard.
SPARK MODULE LOCATION
The spark module is located inside the backguard. The module is mounted by two
tabs which snap into correspoinding slots.
To remove the module from its mounting, use a small, flat bladed screwdriver to
bend the mounting tab toward the module body, freeing the tabs from their slots.
TO REMOVE CONVECTION MOTOR
1. Remove oven door.
2. Remove Phillips head screws from fan

igniter. the round Carborundum igniter CANNOT be substituted for the rectangular
Norton Igniter.
• Remove the burner from the oven. See Bake Burner Removal in this manual.
• Remove the 1/4" hex head screws securing then igniter to the burner.
• Remove the old igniter.
