The motorized damper closes when the appliance is off to keep conditioned air from escaping, then opens automatically just before the burner fires. It is matched to RSD250 chimney fans. It is engineered as part of a mechanical draft system that delivers steady, reliable venting for fireplaces and gas appliances where natural draft falls short. It is sized for 12\" applications to ensure a precise, secure fit.\u003c\/p\u003e\u003cp\u003eMotorized flue dampers are an easy energy-saving upgrade for fireplaces equipped with chimney fans. They also keep rain, debris and pests out of the chimney when the appliance is idle. Select the version that matches your flue size, fan series and system voltage. Adding mechanical draft components to a Mason-Lite fireplace is a proven way to eliminate smoke problems and enjoy a cleaner, more comfortable fire.\u003c\/p\u003e\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eGas Flue Damper\u003c\/li\u003e\n\u003cli\u003eAdaptor\u003c\/li\u003e\n\u003cli\u003eActuator\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eGFD Mechanical Flue Dampers close when the appliance is not in use to prevent conditioned air from escaping through the chimney, and open right before the appliance burner fires up\u003c\/li\u003e\n\u003cli\u003eSeals the flue when the appliance is off\u003c\/li\u003e\n\u003cli\u003eReduces heat loss and cold drafts\u003c\/li\u003e\n\u003cli\u003eOperates automatically with the chimney fan system\u003c\/li\u003e\n\u003cli\u003eSized for the listed flue diameter\u003c\/li\u003e\n\u003cli\u003eImproves home energy efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:16px\"\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eMason-Lite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:16px\"\u003eItem Number\u003c\/th\u003e\n\u003ctd\u003eGFD.212\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:16px\"\u003eSize\u003c\/th\u003e\n\u003ctd\u003e12\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align:left;padding-right:16px\"\u003eProduct Type\u003c\/th\u003e\n\u003ctd\u003eGas Flue Damper\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eDocuments \u0026amp; Files\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0772\/9646\/8151\/files\/Mason-Lite-20pg-Product-Catalog-v3-MAR22-WEB-1.pdf\" target=\"_blank\" rel=\"noopener\"\u003eProduct Catalog\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Mason-Lite","offers":[{"title":"Default Title","offer_id":57897959555255,"sku":"GFD.212","price":1543.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0772\/9646\/8151\/files\/Image_Coming_Soon.webp?v=1793087173","url":"https:\/\/www.efireplacedirect.com\/products\/mason-lite-kw-12-gas-flue-damper-adaptor-and-actuator-for-rsd250-chimney-fan","provider":"efireplacedirect","version":"1.0","type":"link"}
