{"product_id":"superior-24-rigid-direct-vent-for-secure-vent-4-5-7-5-vent-system","title":"Superior 24\" Rigid Direct-Vent for Secure 4.5\/7.5 Vent System","description":"\u003ch3\u003eDescription\u003c\/h3\u003e \u003cp\u003eThe Superior SV4.5L24 is listed in the manufacturer's price book as Material #77L72, described there as \"24\" Rigid DV Vent\", and is grouped under the Secure Vent 4.5\/7.5 Rigid Vent System section of the catalog alongside the other parts sold for this line of fireplaces. A direct-vent fireplace draws every cubic foot of combustion air from outdoors and exhausts every cubic foot of exhaust back outdoors again, through a sealed, co-axial pipe system rather than an open masonry flue. These rigid and flexible pipe sections, elbows and fittings are the components that make up that sealed run between the fireplace and its termination. Rigid sections give the straightest, most efficient run and are the standard choice wherever the vent path allows it, while flexible sections and adapters let the same system route around framing, joists or other obstructions that a rigid run cannot pass through directly.\u003c\/p\u003e \u003cp\u003eAt $135, the SV4.5L24 is priced as a standalone factory part, separate from any fireplace it is ordered with, and it is listed as fitting Secure Vent 4.5\/7.5 Vent System. Vent lengths, elbows, firestops and support components are all sized to the same nominal diameter as the fireplace collar they connect to, so the first step in ordering any of them is confirming which vent system - and which diameter - the fireplace in question actually uses. Firestops and radiation shields are required wherever the vent passes through a combustible wall, floor or ceiling cavity, and are not optional extras - they are the components that keep the surrounding framing at a safe temperature during normal operation. Because a direct-vent run is only as good as its weakest joint, every component in the system should come from the same manufacturer and be rated for the same pressure class; mixing vent brands or types on a single run is not supported by Superior or by most local codes.\u003c\/p\u003e \u003ch3\u003eWhat's Included\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eOne Superior SV4.5L24 - 24\" Rigid DV Vent\u003c\/li\u003e \u003cli\u003eMaterial #77L72, supplied in the manufacturer's packaging\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eKey Features\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eGenuine Superior venting component\u003c\/li\u003e \u003cli\u003eSized to the vent system it belongs to\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\u003eSV4.5L24\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003cth style=\"text-align: left; padding-right: 16px;\"\u003eMaterial #\u003c\/th\u003e\n\u003ctd\u003e77L72\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003cth style=\"text-align: left; padding-right: 16px;\"\u003eDescription\u003c\/th\u003e\n\u003ctd\u003e24\" Rigid DV Vent\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\u003eDirect Vent Component\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\u003eSecure Vent 4.5\/7.5 Rigid Vent System\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":48312826101918,"sku":"SV4.5L24","price":135.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0703\/9542\/9022\/files\/SV4.5L24.webp?v=1790588517","url":"https:\/\/usfireplaceshop.com\/products\/superior-24-rigid-direct-vent-for-secure-vent-4-5-7-5-vent-system","provider":"US Fireplace Shop","version":"1.0","type":"link"}
