The NORGAS vl0500 is a vent limiter designed for use with NORGAS N5C and N5D indoor gas appliance regulators. A vent limiter restricts the vent opening on a gas pressure regulator, limiting the amount of gas that can escape to the atmosphere in the event of a diaphragm failure. This is a required safety component in many indoor installation scenarios where the regulator vent cannot be piped to the outside. Licensed gas fitters and HVAC technicians handling indoor gas piping systems are the primary installers of this component.
This vent limiter is intended for indoor installations where applicable gas codes require the regulator vent port to be fitted with a listed vent limiting device rather than a full vent pipe to the exterior. It is compatible with NORGAS N5C and N5D series regulators. Indoor commercial and residential gas systems operating in confined or semi-enclosed mechanical spaces are the typical application environment for this part.
Compatible with NORGAS N5C and N5D indoor gas appliance regulators.
Installation must be performed by a licensed gas fitter or qualified HVAC technician in accordance with local gas codes and the applicable provisions of the IFGC. Shut off the gas supply and verify zero pressure at the regulator before removing or installing any vent port components. Do not install this vent limiter on regulators located in areas with inadequate ventilation without first confirming code compliance for the specific installation.
