Maxitrol 325-5L600-3/4-LIM Gas Regulator

The Maxitrol 325-5L600-3/4-LIM is a high-performance line pressure gas regulator specifically engineered for 2-PSI and 5-PSI piping systems using natural gas or LP gas. As a veteran in the field, you know the importance of a lever-acting design; this unit delivers precise control from full capacity down to pilot-flow, ensuring positive dead-end lockup. With a 3/4" NPT connection and a robust 425,000 BTU/hr maximum capacity, it is the standard for upstream installation before appliance-level regulators in residential or commercial mechanical rooms. The integrated Overpressure Protection Device (OPD) and factory-installed vent limiter eliminate the need for costly vent piping to the outdoors, provided the regulator is mounted in the horizontal upright position. This CSA certified (ANSI Z21.80/CSA 6.22) component serves as a critical 2-PSI to inches water column interface, maintaining a stable 7-11" wc outlet pressure even under fluctuating inlet conditions up to 5 PSI.

• Internal Safety: Factory-assembled Overpressure Protection Device (OPD) limits downstream pressure in the event of a primary regulator failure.
• Ventless Installation: The included 12A39 vent limiter allows for indoor application without external vent lines, saving labor and material costs.
• System Versatility: Compatible with CSST, semi-rigid copper, and black iron pipe systems for multi-appliance gas distribution.
• Superior Regulation: Advanced lever-acting mechanism ensures stable delivery and exceptional lockup characteristics for modern high-efficiency boilers and furnaces.

Can this regulator be used for both Natural Gas and Propane?
Yes. It is rated for a maximum 5 PSI inlet with natural gas and 2 PSI for LP applications, effectively dropping "pounds to inches" for downstream equipment.

Is outdoor mounting permitted with the vent limiter?
The 12A39 vent limiter is designed for indoor use. For outdoor settings, a vent protector must be used to prevent the ingress of moisture and debris into the breather hole.

What is the proper mounting orientation for this model?
When utilizing the vent limiter, the unit must be installed in a horizontal upright position to ensure the internal ball-check mechanism functions correctly.
