Maxitrol 325-7A-1 1/2-12A49 Regulator

The Maxitrol 325-7A-1 1/2-12A49 Regulator is a high-performance lever acting design gas regulator engineered for precision in residential, commercial, and industrial 2 PSI piping systems. This model is factory-equipped with a 12A49 vent limiter, facilitating indoor installation by eliminating the requirement for external vent piping. It manages a massive 1,250,000 BTU/hr max capacity, making it ideal for high-demand gas appliance pressure regulation where maintainable positive dead-end lock-up is critical for safety. This specific configuration features 1 1/2 inch NPT connections and is calibrated for a 4-12 inch wc outlet pressure range using the violet spring. Designed to handle a 5 PSI max inlet pressure for natural gas and 2 PSI for LP, this line pressure regulator ensures stable delivery from full flow down to pilot flow. The rugged aluminum housing and certified internal components provide reliable performance for licensed contractors managing complex fuel gas piping systems.

Key Benefits

• Integrated Vent Limiter: Includes the 12A49 device, allowing for compliant indoor mounting without the need to run vent lines to the building exterior.
• Positive Dead-End Lock-Up: The lever-acting design ensures a secure seal during static conditions, preventing downstream pressure equalization.
• Dual-Fuel Compatibility: Certified for use with natural gas, LP, and mixed gas-air systems, providing versatility for various job site requirements.
• High Capacity Output: Supports large-scale equipment with a 1.25 million BTU/hr rating and a broad 4-12" w.c. field-adjustable range.
• Precision Control: Maintains steady outlet pressures even at low differential pressures, ensuring consistent pilot light and main burner operation.

Common Questions

• Do I need to vent this regulator outside? No, this model includes the 12A49 vent limiter, which is CSA certified for indoor use without an external vent line, provided it is mounted in the upright horizontal position.
• Can I use this for both Natural Gas and Propane? Yes, it is suitable for both. However, the max inlet pressure ratings differ: 5 PSI for Natural Gas and 2 PSI for Propane.
• Is this regulator suitable for outdoor use? While the standard aluminum housing is durable, for outdoor installations subject to the elements, the "Imblue" coated version (suffix B) or a 13A25 vent protector is typically recommended.
