Reznor 64676 LP Burner Orifice

The Reznor 64676 LP Burner Orifice meters liquid propane gas into the burner assembly in HVAC systems, controlling the fuel flow entering the combustion zone. Its calibrated opening regulates the volume of propane passing through the burner inlet for the specified fuel application. The orifice mounts at the burner gas connection and directs metered fuel toward the combustion area for mixing with combustion air. This configuration maintains the intended fuel-delivery path within compatible heating equipment. The orifice establishes the gas-flow restriction required for the corresponding LP burner arrangement.
