A configuration kit adapts a vent-free fireplace system to the specific installation it is going into - vent-free appliances can typically be installed in more than one way, and the configuration kit is what supplies the parts particular to the option chosen. Because vent-free systems draw their combustion air from, and return their combustion by-products to, the room itself, the exact configuration chosen affects both the required room size and the ventilation guidance in the appliance manual.\u003c\/p\u003e \u003cp\u003eAt $449, the HTFLO-EK-4.5 is priced as a standalone factory part, separate from any fireplace it is ordered with, and it is a shared component used across a wide range of Superior appliances. Configuration kits are installed as part of the initial setup of the appliance, before it is first fired, following the specific configuration instructions in the manual for the option chosen. Because vent-free installation requirements - minimum room size, required ventilation, glass media loading - vary by configuration, always cross-reference the kit against the appliance manual for the exact model it will be used with. Confirm the exact model number of the vent-free system before ordering, since configuration kits are matched to a specific appliance rather than sold as a universal accessory.\u003c\/p\u003e \u003ch3\u003eWhat's Included\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eOne Superior HTFLO-EK-4.5 - HeatFlo Flex Extension Kit, 60\" length\u003c\/li\u003e \u003cli\u003eMaterial #F4578, supplied in the manufacturer's packaging\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eKey Features\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eGenuine Superior configuration kit\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eSpecification\u003c\/h3\u003e \u003ctable\u003e \u003ctbody\u003e \u003ctr\u003e\n\u003cth style=\"text-align: left; padding-right: 16px;\"\u003eModel #\u003c\/th\u003e\n\u003ctd\u003eHTFLO-EK-4.5\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003cth style=\"text-align: left; padding-right: 16px;\"\u003eMaterial #\u003c\/th\u003e\n\u003ctd\u003eF4578\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003cth style=\"text-align: left; padding-right: 16px;\"\u003eDescription\u003c\/th\u003e\n\u003ctd\u003eHeatFlo Flex Extension Kit, 60\" length\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003cth style=\"text-align: left; padding-right: 16px;\"\u003eProduct Type\u003c\/th\u003e\n\u003ctd\u003eConfiguration Kit\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003cth style=\"text-align: left; padding-right: 16px;\"\u003ePrice Book Section\u003c\/th\u003e\n\u003ctd\u003eConfiguration Kits\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003cth style=\"text-align: left; padding-right: 16px;\"\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eSuperior\u003c\/td\u003e\n\u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e","brand":"Superior","offers":[{"title":"Default Title","offer_id":48312809881758,"sku":"HTFLO-EK-4.5","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0703\/9542\/9022\/files\/HTFLO-DV45_01.webp?v=1790330578","url":"https:\/\/usfireplaceshop.com\/products\/superior-heatflo-flex-extension-kit-60-length-configuration-kit","provider":"US Fireplace Shop","version":"1.0","type":"link"}
