• Helps prevent flame irregularities and cycling issues caused by improper gas metering
• Used where a #45 natural gas orifice specification is required by the appliance

• Turn off gas supply and electrical power before servicing; follow all safety and local code requirements
• Install only if the #45 NG size is specified for your appliance; do not file or enlarge the orifice
