Overview

The Marshall 1652-CFF is a robust second-stage regulator designed for LP gas systems, providing dependable downstream control after a first-stage regulator. Its backmount layout keeps critical components aligned in tight spaces, while the 11-inch water column output helps maintain steady pressure across compatible appliances. This regulator is built for reliability in residential, commercial, and outdoor installations where consistent gas flow matters.

With its clear inputs and outputs, the 1652-CFF supports practical configurations without sacrificing ease of installation. The design emphasizes straightforward connections and a compact footprint, helping installers keep lines neat and accessible for maintenance or adjustments over time.

Key specifications

  • 11" Water Column Output
  • 1/2" Female NPT Input x 3/4" 90 Degree Female NPT Output — Backmount Design
  • 10 PSI Required Input: Must be used in conjunction with a First Stage High Pressure 10 PSI regulator at the tank
  • Adjustable Output: 9" – 13" Water Column
  • 1,000,000 BTU Max Capacity
  • Replaces: Rego LV4403B46R, Fisher R652-CFF, Cavagna 998LP-03

Usage and compatibility

  • Backmount configuration keeps lines organized and accessible in constrained spaces
  • Designed to work with standard LP systems, pairing with a compatible first-stage regulator at the tank
  • Safe installation practices are recommended; verify proper connections and pressure ratings before operation

Practical scenarios

Ideal for setups requiring a dedicated secondary regulator downstream of a 10 PSI first stage. The adjustable 9–13" WC range enables tuning to match the needs of grills, space heaters, or outdoor cooking stations, while maintaining steady output as loads vary.

Installation and maintenance

Plan for a clean mounting area and secure connections to minimize leaks and vibration. Periodic checks of fittings and seals help ensure ongoing performance, and keeping spare parts on hand can reduce downtime during routine maintenance or replacements.
