Component Access and Removal

Manifold System Components:

Gas Valve, Gas Valve Orifice, Gas Tubing, Manifold,
and Regulator Removal
NOTE: The following components will need to be
removed in order to gain access to the components of
the manifold. Refer to the appropriate component
access removal section for proper removal instructions
of these components.
Preliminary Steps
• Disconnect power cord from electrical supply
source.
• Remove grates
• Remove control knobs
• Remove burner heads with caps
• Remove venturi
• Remove electrodes and inner distribution rings
• Remove cooktop pan
Gas Valve Removal
The gas valves are mounted to the manifold pipe with
bolts that pass through a bracket on the side of the
pipe, and are threaded into the body of the valve. To
remove the gas valves, follow the preliminary steps list-
ed at the beginning of this section first. Next, remove
the ring light and valve switch. Disconnect the flexible
gas tubes from the valve and extract the bolts from the
valve body and mounting bracket. Now, pull or twist the
valve off of the manifold pipe. (See Figure 4-11).

Gas Valve Orifice

Each gas valve has two by-pass screw orifices installed
into it. To remove these orifices, turn off the gas supply
source. Next, follow the preliminary steps listed at the
beginning of this section. Then, using a small flat blad-
ed screwdriver, insert the screwdriver down along the
opening through the control panel glass and cooktop
pan. (The by-pass screws are located on the left side
of the valve.) Now, turn the by-pass screw orifice coun-
terclockwise to remove and lift the orifice out of the
valve. (See Figure 4-12).
