Maxitrol 325-5-1 Regulator

The Maxitrol 325-5-1 is a high-performance 1-inch NPT gas regulator engineered for residential, commercial, and industrial pounds to inches reduction. Featuring a lever-acting design with a high-leverage valve linkage, this unit provides the positive dead-end lockup required for modern high-efficiency appliances. It handles a 10 PSI max inlet pressure and manages a 325,000 BTU/hr capacity, making it a reliable choice for main burner and pilot load applications. The factory-set 4-12" w.c. outlet pressure range, controlled by a violet spring, ensures precise regulation across a variety of fuel gases, including natural gas and LP gas-air mixtures. Constructed from durable aluminum with corrosion-resistant internal components, this appliance regulator supports multi-positional mounting. To maintain ANSI Z21.18/CSA 6.3 certification, ensure the vent remains unobstructed or utilize a vent limiting device where local codes permit. This gas pressure regulator is a staple for contractors requiring consistent lock-up pressure and stable flow control.

• Broad Compatibility: Optimized for use with natural, manufactured, mixed, and liquefied petroleum gases.
• Precision Control: The lever acting design enables accurate pressure management from full flow down to pilot levels.
• Durable Construction: Features a rugged aluminum housing and corrosion-resistant parts for long-term field reliability.
• Flexible Installation: Supports multi-poise mounting to accommodate tight manifold configurations.
• Safety Compliance: Engineered to meet strict utility specifications for positive dead-end lock-up performance.

Can the 325-5-1 be installed outdoors?
Yes, provided it is protected from the elements. A 13A15-5 vent protector is recommended to prevent rain, ice, or insects from obstructing the vent port. If installed in a flood-prone area, the vent must be extended above the expected water level.

Is a vent limiter included with this model?
No, the Maxitrol 325-5-1 does not include a 12A39 vent limiting device by default. If your application requires indoor venting without a dedicated line to the outdoors, this component must be purchased separately.

What is the difference between a line regulator and this appliance regulator?
While often used interchangeably in the field, this model is certified as an appliance regulator for pounds to inches reduction. It is designed to be the final stage of pressure control before the gas reaches the burner assembly.
