Norgas N5BN-1000-Y-VL0375 Gas Regulator 15 Psi Vent Limiter

Product Description

The NORGAS N5BN-1000-Y-VL0375 is a second-stage, self-operating gas pressure regulator from the N5 Series, designed for reliable pressure regulation in residential, commercial, and industrial gas distribution systems. It features a 1-inch FPT x FPT pipe connection with a top outlet and an integrated vent limiter that allows indoor installation without the need to run external vent lines to the outside. Certified to CSA 6.22 and ANSI Z21.80, this regulator is built to meet the demands of professional gas system installations. The extended corrosion resistance of the N5 Series makes it suitable for a range of application environments where performance and durability are required.

The N5BN-1000-Y-VL0375 is suited for second-stage regulation on natural gas and LP gas systems in residential homes, light commercial buildings, and industrial facilities. It handles a 15 PSI inlet pressure and delivers a regulated outlet pressure in the 12 to 14 inches water column (WC) range, which is standard for downstream appliance supply in typical gas distribution configurations. The built-in vent limiter eliminates the need to pipe vent lines outdoors, making this regulator particularly practical for installations in mechanical rooms, utility spaces, and other interior locations.

Compatibility

Designed as an OEM-style replacement or new-installation second-stage gas pressure regulator for residential, commercial, and industrial gas distribution systems requiring a 1-inch NPT connection and 15 PSI inlet rating.

Installation Notes

Installation should be performed by a licensed gas fitter or plumber in accordance with local codes and the International Fuel Gas Code (IFGC). Shut off the gas supply completely and verify zero pressure in the line before removing or installing any regulator. Inspect all fittings and apply appropriate thread sealant rated for gas service before making connections. The integrated vent limiter must not be blocked or modified after installation.
