Decorative media - glowing embers, volcanic stone, crushed glass or mosaic brick - is what finishes the look of the firebox floor and fills in the visual gaps around the log set or burner, and it plays a real role in how convincing the finished flame pattern looks once the fireplace is lit. Glowing embers and volcanic stone suit the traditional, log-set look, catching and reflecting the flame the way a real ember bed does, while crushed glass and mosaic brick liners are used on contemporary and linear models where the flame is meant to be seen rising through the media itself rather than around a log set.\u003c\/p\u003e \u003cp\u003eAt $224, the RIVROCK-25PK 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. Media is placed directly in the firebox by hand, following the layout diagram in the appliance manual, and should never be piled over or against the burner ports, pilot assembly or ignition components, since doing so can disrupt how the fire burns. Glass and stone media are typically sold by the bag, sized to cover a specific firebox area, so ordering more than one bag is common on wider fireplaces - check the coverage area against the size of the firebox being filled. Because media sits directly in the flame path, only media rated for use in a gas fireplace should be used; general household decorative glass or stone is not rated for the sustained heat a firebox reaches.\u003c\/p\u003e \u003ch3\u003eWhat's Included\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eOne Superior RIVROCK-25PK - River Rock, 25 Piece Kit\u003c\/li\u003e \u003cli\u003eMaterial #F3775, supplied in the manufacturer's packaging\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eKey Features\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eGenuine Superior decorative fire media\u003c\/li\u003e \u003cli\u003ePlace media only as shown in the appliance manual\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\u003eRIVROCK-25PK\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003cth style=\"text-align: left; padding-right: 16px;\"\u003eMaterial #\u003c\/th\u003e\n\u003ctd\u003eF3775\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003cth style=\"text-align: left; padding-right: 16px;\"\u003eDescription\u003c\/th\u003e\n\u003ctd\u003eRiver Rock, 25 Piece Kit\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\u003eFireplace Media\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\u003eFloor Media 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":48312807948446,"sku":"RIVROCK-25PK","price":224.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0703\/9542\/9022\/files\/RIVROCK-25PK.webp?v=1790318215","url":"https:\/\/usfireplaceshop.com\/products\/superior-river-rock-25-piece-kit","provider":"US Fireplace Shop","version":"1.0","type":"link"}
