Manifold Assembly Kit With Gas Proportional Valve (For LP)

Rheem LP Manifold Assembly Kit – OEM Fuel Delivery System for Tankless Applications

The Rheem RTG20329E is a factory-assembled manifold kit that includes a gas proportional valve and is configured specifically for use with Rheem tankless gas water heaters operating on liquid propane (LP). This assembly plays a critical role in modulating gas input based on water flow rate and temperature demand, ensuring accurate burner performance and system stability.

Engineered as a direct replacement for the original manifold, this kit is ideal for restoring proper fuel delivery in cases of valve failure, ignition irregularities, or burner performance degradation. The integrated gas valve modulates LP flow proportionally, maintaining combustion efficiency while meeting safety parameters.

Contractor-Focused Advantages

• OEM Precision – Direct-fit replacement manifold with LP-configured proportional valve; ensures compatibility with factory specifications.
• Efficient Combustion Control – Valve responds to demand in real time, reducing cycling and supporting system efficiency.
• Reduces Error Codes – Addresses faults related to fuel metering and combustion instability.
• Factory-Calibrated Components – No field adjustment required; engineered for plug-and-play installation with approved models.

Technical Specifications

• Part Number: RTG20329E
• Gas Type: Liquid Propane (LP)
• Component: Manifold assembly with integrated gas proportional valve
• Application: Rheem tankless LP gas water heaters (model compatibility must be verified)

Installation Guidelines

This manifold assembly is a gas-handling component and must be installed by a licensed technician. Improper installation can result in combustion issues, performance loss, or safety hazards. Ensure gas supply is shut off and unit is de-energized before replacement. After installation, a complete gas leak test and functional system check are required per Rheem guidelines and local codes.

Field Use and Maintenance

• Service Tip: Replace the manifold if combustion diagnostics point to fluctuating or insufficient gas delivery or if the existing valve has failed electrically.
• Best Practice: Always confirm the correct gas type (LP vs. NG) and part number before installation. This part is LP-specific.
