Suburban RV Range Manifold Kit | 521325 | 22" Range | Replaces 521103

Restore reliable burner and oven operation to your Suburban 22" RV range with the Suburban 521325 RV Stove/Range Manifold Kit. This genuine Suburban replacement is engineered for 22" Suburban conventional burner ranges featuring a black oval-style thermostat knob — providing a complete oven burner tube kit and updated manifold for proper gas distribution to your burners and oven.

For 22" Suburban Conventional Burner Ranges

The 521325 is specifically engineered for 22" Suburban Conventional Burner Ranges with:

• Oven Burner Tube Kit configuration
• Black Oval-Style Thermostat Knob

Verify your existing range dimensions and configuration before ordering — Suburban makes multiple range sizes, and the manifold kits are not interchangeable across sizes.

Cross-Reference: Replaces 521103

The 521325 is the direct replacement for the earlier Suburban 521103 manifold kit (SRNA/SCNA Copreci style). If your existing kit shows part number 521103, this 521325 is the current production successor — same Copreci-style design, same fitment.

Considering Other Suburban Range Manifold Kits?

We also carry Copreci-style manifold kits for other Suburban range types:

• Suburban 521324 Manifold Conversion Kit — for 17" Suburban ranges (BSI oval-knob to Copreci conversion)
• Suburban 521322 Manifold Kit — for 17" Suburban short range with brushed nickel knobs (direct Copreci replacement)
• Suburban 521323 Manifold Kit — for SRNL model Suburban ranges with brushed nickel thermostat knob

Match the manifold kit to your specific Suburban range model — they're not interchangeable across model series.

ISO 9001:2015 Certified

The 521325 is manufactured under ISO 9001:2015 quality certification — Suburban's commitment to consistent quality standards in propane appliance components.

Complete Kit — Includes Valve and Knob

The kit ships with the full assembly ready to install:

• Manifold assembly
• Valve included
• Knob included

That's a meaningful detail — many manifold replacements require sourcing the valve and knob separately. The 521325 arrives as a complete drop-in assembly.

⚠️ Professional Installation Required

Range manifold installation involves propane connections, gas distribution adjustments, and burner setup. Improperly installed propane components are a fire and explosion risk. Installation should be performed by a qualified RV service technician. Always leak-test all connections after installation.
