Weber 64564 LP Manifold & Control Valve Assembly for GENESIS 325 & 335 Series Gas Grills – 2022 & Newer

What Problem This Part Solves

The manifold assembly is responsible for delivering and regulating fuel to the grill burners. Problems with the manifold or valves can cause:

• Burner that will not light
• Burner that will not stay lit
• Uneven or restricted gas flow
• Control valve that is difficult to turn
• Valve that no longer regulates flame correctly
• Gas leakage around a valve or manifold connection
• Damaged manifold tubing
• Broken valve stems
• Problems resulting from physical or corrosion damage

If only the igniter is malfunctioning, inspect the ignition system before replacing the manifold because ignition components are listed separately in Weber's schematic.

Important: LP Only

Weber 64564 is specifically an LP / liquid propane manifold assembly. It should not be installed on a natural-gas grill.

Gas manifolds are fuel-specific because valve and orifice requirements differ between propane and natural gas. Do not attempt to convert a grill simply by swapping manifolds unless the conversion is specifically approved by Weber for that exact grill.

Installation / Use Instructions

1. Shut off the propane cylinder completely, disconnect the regulator, and allow the grill to cool before service.
2. Remove the control knobs and control panel as needed, disconnect the gas connections, and replace the original manifold with Weber 64564 according to the factory configuration.
3. Reassemble the grill and leak-test every disturbed gas connection with an approved leak-detection solution before lighting the grill.

Because this repair involves the fuel-delivery system, use a qualified gas-grill technician if you are not experienced servicing gas valves and manifold assemblies.

FAQ Section

What is Weber 64564?
It is the genuine Weber LP manifold assembly for select 2022 GENESIS 325/335 Series gas grills. Weber's factory schematics describe it as “LP manifold assembly, Genesis 325 (2022).”

Is Weber 64564 for propane or natural gas?
It is for liquid propane only. Do not use it as a replacement manifold for a natural-gas GENESIS grill.

Does Weber 64564 fit the GENESIS E-325s?
Yes, on compatible LP versions. Weber's official schematic for GENESIS E-325s model 35310001 lists 64564.

How many control valves does Weber 64564 have?
Replacement-parts documentation describes it as a four-valve assembly for compatible GENESIS 325/335 models with the additional sear or side-burner control.

Does Weber 64564 include the control panel and igniter?
Those components are shown separately in Weber's parts diagrams. For example, Weber lists the 64483 control panel assembly and ignition components separately from 64564, so they should not be assumed to be included.
