This orifice is the replacement for the gas metering component used in a number of compatible Enviro gas appliances, fitting 3 compatible models on record. The Enviro Orifice #55 Bullet (part 50-4584) replaces the worn bullet orifice that controls gas flow in compatible Enviro gas stoves and fireplaces.

Purpose

A bullet orifice restricts and meters the flow of gas into the burner system, shaped to seat directly into the gas line. When this component wears or becomes damaged, gas flow to the burner can become inconsistent.

Key Benefits

• Restores factory-calibrated gas flow for consistent flame performance
• Helps maintain intended heat output and combustion efficiency
• Genuine Enviro part, not an aftermarket reproduction
• Direct-fit design for compatible models, no modification needed

Other Notes

Gas metering components should not be ignored once flame quality or heat output seems off. Installation and adjustment of gas orifices should be performed only by a licensed gas technician, in accordance with local codes.

When replacing this orifice, it is worth having a technician inspect the associated burner assembly and gas valve for wear, since these components work together to regulate flame and heat output.
