It manages ignition sequencing and burner operation to keep the boiler running safely and within its operating parameters. The module runs on 120 volts AC input with a 24-volt AC control circuit at 60 hertz, and carries a 0.5-amp current rating. It meets UL 353, ANSI Z21.20, and CSA C22.2 standards, making it a code-compliant replacement for licensed technicians working on residential or light commercial heating systems.\u003c\/p\u003e\n\u003cp\u003eThis control module is rated for natural gas applications and is used on gas-fired water boilers, specifically GWA model and brand 2 systems as noted by the manufacturer. It is a direct-fit control replacement suited for boiler service calls where the existing module has failed, is fault-locked, or is showing erratic ignition behavior. HVAC and plumbing technicians handling boiler service work are the primary installers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e120-volt AC input power with 24-volt AC control voltage at 60 hertz\u003c\/li\u003e\n  \u003cli\u003eRated for natural gas applications\u003c\/li\u003e\n  \u003cli\u003e0.5-amp current rating\u003c\/li\u003e\n  \u003cli\u003eMeets UL 353, ANSI Z21.20, and CSA C22.2 standards\u003c\/li\u003e\n  \u003cli\u003eOEM-specified control module for gas-fired water boiler systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on GWA and 2 model gas-fired water boilers as specified by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or plumber familiar with gas-fired hydronic heating systems. Shut off all electrical power and close the manual gas shutoff valve before removing the existing control module. Follow IFGC and NEC guidelines as applicable for gas appliance controls. Confirm all wiring connections are secure and the gas supply is leak-tested before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInput Voltage\u003c\/strong\u003e: 120 volts AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eControl Voltage\u003c\/strong\u003e: 24 volts AC at 60 hertz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Rating\u003c\/strong\u003e: 0.5 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGas Type\u003c\/strong\u003e: Natural Gas\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: UL 353, ANSI Z21.20, CSA C22.2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WILLIAMSON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: WI-381330014WT\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WILLIAMSON","offers":[{"title":"Default Title","offer_id":51344253419826,"sku":"WI-381330014WT","price":239.26,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/381330014wt_1.jpg?v=1782032575","url":"https:\/\/voomisupply.com\/products\/williamson-wi-381330014wt-gas-boiler-control-module","provider":"Voomi Supply","version":"1.0","type":"link"}
