Norgas n5a-0750-s-vl0125 Gas Regulator 0.75 in Npt 2 Psi

Product Description

The NORGAS n5a-0750-s-vl0125 is a 3/4-inch NPT gas pressure regulator rated at 2 PSI with CSA certification and an integrated vent limiter. It delivers capacity up to 340,000 BTU/h, making it suitable for medium- to high-demand gas appliance installations. The 7-11 inch spring range allows field adjustment of outlet pressure within that band. Licensed gas fitters and HVAC technicians install this regulator as part of a gas train serving furnaces, boilers, unit heaters, and similar natural or LP gas equipment. The vent limiter is factory-installed and limits venting requirements in accordance with applicable gas codes.

This regulator is well-suited to residential and light commercial gas systems where a 3/4-inch line size is present and where outlet pressure must be regulated and held steady under varying load conditions. At up to 340,000 BTU/h capacity, it covers a wide range of single-appliance and small manifold applications. The integrated vent limiter reduces the need for remote venting of the regulator body, which simplifies installation in tight mechanical rooms or indoor environments where full vent piping is impractical.

Key Features

• 3/4-inch NPT inlet and outlet for direct in-line installation in standard gas piping
• 2 PSI maximum inlet pressure rating with CSA certification
• 7-11 inch water column spring range for outlet pressure adjustment
• Up to 340,000 BTU/h capacity supports high-demand appliances and small manifolds
• Factory-installed vent limiter reduces remote vent piping requirements
• CSA-certified construction meets gas code requirements for residential and commercial use

Compatibility

Designed as an OEM-style replacement or new-installation gas pressure regulator for 3/4-inch NPT gas lines serving natural gas or LP appliances requiring a 2 PSI, 7-11 inch water column regulated supply.

Installation Notes

Installation must be performed by a licensed gas fitter or qualified HVAC technician in accordance with IFGC, local gas codes, and the appliance manufacturer's instructions. Shut off the gas supply at the service valve and verify zero pressure with a manometer before opening the line. Install the regulator with flow direction matching the arrow cast on the regulator body, and pressure-test all joints after reassembly before returning the system to service. Do not exceed the rated inlet pressure or remove the vent limiter assembly.
