Suburban Copreci Range Manifold Kit | 521323 | SRNL Brushed Nickel

Restore reliable gas distribution to your Suburban SRNL Series RV range with the Suburban 521323 Copreci Manifold Kit. This complete Copreci-style manifold assembly is a genuine Suburban replacement for SRNL model ranges — featuring round-tube manifold construction, cylinder-style brass oven thermostat, and a premium brushed nickel thermostat knob that complements stainless steel and modern RV kitchen interiors.

For Suburban SRNL Model Ranges

The 521323 is specifically engineered for Suburban SRNL model RV ranges. Verify your existing range model on the manufacturer label before ordering — Suburban makes multiple range model lines, and the manifold kits are not interchangeable across model series.

Cross-Reference: Replaces 521179

The 521323 is the direct replacement for the earlier Suburban 521179 manifold kit. If your existing kit shows part number 521179, this 521323 is the current production successor — same Copreci-style design and same fitment for SRNL ranges.

Premium Brushed Nickel Finish

One of the standout features of the 521323 is its brushed nickel thermostat knob — a premium finish upgrade that:

• Complements stainless steel appliances and modern RV interior finishes
• Updates the look of older Suburban ranges that came with black or white knobs
• Provides a contemporary aesthetic consistent with current RV kitchen design trends

Complete Kit — Manifold, Thermostat, and Burner Valves

The 521323 arrives as a complete drop-in assembly with everything needed:

• Copreci-style manifold assembly with round-tube design
• Cylinder-style brass oven thermostat (without microswitch)
• Top burner valves
• Brushed nickel thermostat knob

That's a meaningful detail — many manifold replacements require sourcing valves and knobs separately. The 521323 ships as a single complete kit.

Considering Other Suburban Range Manifold Kits?

The 521323 is specifically for SRNL ranges. 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, sibling to this 521323 in the brushed nickel finish family)
• Suburban 521325 Manifold Kit — for 22" Suburban Conventional Burner Ranges with black oval-style thermostat knob

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

⚠️ 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.
