{"product_id":"superior-50-piece-bulk-outside-air-kit-collar-only-kit","title":"Superior 50-Piece Collar-Only Outside Air Kit","description":"\u003ch3\u003eDescription\u003c\/h3\u003e \u003cp\u003eThe Superior AK4B is listed in the manufacturer's price book as Material #F1094, described there as \"50 piece Bulk Outside Air Kit - Collar Only Kit\", and is grouped under the Outside Air Kits section of the catalog alongside the other parts sold for this line of fireplaces. Some fireplace and log set installations draw their combustion air from indoors rather than through a sealed direct-vent system, and an outside air kit is what lets that same appliance instead pull its combustion air from outdoors, through a dedicated duct run. That matters most in tightly sealed, well-insulated homes, where an appliance drawing combustion air from the room can compete with other exhaust appliances - range hoods, clothes dryers, bathroom fans - for the same limited supply of indoor air.\u003c\/p\u003e \u003cp\u003eAt $730, the AK4B 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. An outside air kit installs at the collar built into the back or side of the appliance, with the flexible duct run to the exterior sized and routed according to the installation manual for that specific fireplace. Local code in many jurisdictions requires an outside air supply on solid-fuel and some gas appliances installed in tightly sealed new construction, so it is worth checking local requirements before deciding whether this kit is optional or required. Because the kit is sized to a specific appliance's air intake collar, confirm the exact model number of the fireplace or stove it will be installed on before ordering.\u003c\/p\u003e \u003ch3\u003eWhat's Included\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eOne Superior AK4B - 50 piece Bulk Outside Air Kit - Collar Only Kit\u003c\/li\u003e \u003cli\u003eMaterial #F1094, supplied in the manufacturer's packaging\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eKey Features\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eGenuine Superior air 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\u003eAK4B\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003cth style=\"text-align: left; padding-right: 16px;\"\u003eMaterial #\u003c\/th\u003e\n\u003ctd\u003eF1094\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003cth style=\"text-align: left; padding-right: 16px;\"\u003eDescription\u003c\/th\u003e\n\u003ctd\u003e50 piece Bulk Outside Air Kit - Collar Only 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\u003eCombustion Air 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\u003eOutside Air 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":48312859459742,"sku":"AK4B","price":730.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0703\/9542\/9022\/files\/iqz80p1flgxobgjfhuwc.png?v=1790589307","url":"https:\/\/usfireplaceshop.com\/products\/superior-50-piece-bulk-outside-air-kit-collar-only-kit","provider":"US Fireplace Shop","version":"1.0","type":"link"}
